- 9600
- 19200
- 8400
- 57600
- 76800
- 115200
FAKATOKANGA: 115,200 baud rate can only be used with certain devices, such as the iVu® XT-RB router. It can NOT be used on the same MS/TP network with devices such as RTU Open controllers as they do not support this baud rate.
Mo te whirihora i te Reiti Baud me te Wāhitau MAC, whakatere ki nga Tautuhinga BAS i te Atanga Kaiwhakamahi ma te whakamahi i te Tahua / Tautuhinga / Tautuhinga Whatunga / BACNET. Tirohia te Whakaahua 3.

FAKATOKANGA: You must cycle power after changing any Network Settings. SystemVu can be connected to the following devices
- All i-Vu BACnet MS/TP routers
- All current i-Vu CCN devices
- Third-party BACnet MS/TP routers
- System Touch over MS/TP
- Equipment Touch over Rnet
- Carrier Rnet Zone Sensors
FAKATOKANGA: SystemVu is a BACnet MS/TP master controller. Valid MAC addresses for master nodes are 0 – 127.
FAKATOKANGA: If SystemVu cannot be communicated with over BACnet, then ensure that the protocol has been correctly set and the controller has been power cycled if the protocol settings were changed.
TE WHAKANUI KI TE BACNET MS/TP
- In general, all wiring and installation techniques should follow the Open Controller Network Wiring Guide, Catalogue No. 11-808-461-01, instructions. However, please note the following details and exceptions that MUST be observed on networks containing SystemVu controllers.
Tauera Whakawhitiwhiti me te Waea
- Ko te taura whakawhiti korero me te waea e whakamahia ana i roto i te whatunga ka kaha te pa ki te mahi o te whakawhitiwhiti whatunga i runga i taua waea. Whaia nga korero e whakaatuhia ana i te Ripanga 1 hei mahi pai mo te waea waea ki nga whatunga MS/TP BACnet.
Ripanga 1 — BACnet MS/TP Waea Whakaata

FAKATOKANGA
- Ko nga tohu me nga waitohu a te roopu tuatoru nga taonga a o raatau rangatira.
KI TE WAERE TE KAUPAPA KAUPAPA
- Partially cut, then bend and pull off 1 in. of the outer jacket of the cable(s). Do not nick the inner insulation. See Fig. 4.
- Strip about 0.25 in. (0.6 cm) of the inner insulation from each wire. See Fig. 4.
- If wiring two cables to the controller, twist together the shield wires from both cables.
- Insert the wires into the appropriate terminal block (see Figs 7 and 8 on page 6). Take care that the drain wire is electrically isolated, where exposed.
- All connections should be made with power turned off to all the network devices and SystemVu controllers.

WHAKATAHI
POSSIBLE COMMUNICATIONS FAILURE
- Do not allow more than 0.125 inch (0.3 cm) bare communication wire to protrude. See Fig. 5.
- If bare communication wire contacts the cable’s foil shield, shield wire, or a metal surface other than the terminal block, communications may fail.
- Best practice is to tape wires up to the BAS plug to prevent contact with any metal. See Fig. 6.

FAKATOKANGA: Do not ground the shield to earth ground or to the controller’s power ground. The PROT485 and the individual controllers allow the shield to float a limited amount so that there are no ground loops. If the voltage i runga i te whakangungu rakau ka nui rawa, e pa ana ki te whenua o te whenua, katahi ka nui atu te voltagka whakaheke toto ki nga taputapu whakamarumaru i runga i te PROT485, i runga ranei i nga kaiwhakahaere.
Hoahoa Whatunga
Me nga kaiwhakahaere rītaha-a-rohe, mo ia paerewa RS-485, ko te nui rawa o te maha o nga pona e taunakitia ana mo ia wahanga/katua e whakawhirinaki ana ki te reiti o te kupenga.
- 38,400 baud = mōrahi o ngā kōpuku 15 me tētahi pouara
- 76,800 baud = mōrahi o ngā kōpuku 31 me tētahi pouara
Please note that the SystemVu controller is a LOCALLY biased device as opposed to the OPEN product line, which are NETWORK biased device.
- Therefore, the BT485 device is NOT used in a SystemVu-only network, and NOT used in a network composed of SystemVu and OPEN products together.
- In addition, the end-of-line / end-of-net switches on OPEN products and routers are NOT used with SystemVu controllers on the bus. Since these switches may also add network biasing, they are not needed with a locally biased product. There are no end-of-line switches on SystemVu products.
- FAKATOKANGA: Kia mahara: Me whakamahi he parenga 120 Ohm hei whakamutu i te pahi i nga pito e rua i runga i nga whakaritenga paerewa RS-485. E taunaki ana te taputapu TERM485.
- With careful wiring practices, one network segment can use up to 4,000 feet of network wire. However, the best results are achieved when the total wire length on a trunk is limited to 2000 feet.
- In addition, the use of a repeater (the REP485 is the only currently allowed repeater) for network segments over 2000 feet of wire is encouraged, but not mandatory. Please refer to the Open Controller
- Network Wiring Guide for detailed REP485 installation instructions. Note that the REP485 counts as a node on both network segments it connects.
- Ko te whakamahinga o te taputapu PROT485 e tino taunakitia ana mo nga waahanga whatunga katoa me nga kaiwhakahaere SystemVu. Tena tirohia te Aratohu Waea Waea Whakatuwhera Kaiwhakarite mo nga tohutohu whakaurunga PROT485.
- Finally, please note that rigorous adherence to the wiring hygiene recommendations here and in the Open Controller Network Wir-ing Guide will produce the best network results.
- Ko nga kaiwhakahaere SystemVu me hono te waea BAS ki te taapiri, te iti, me te waea whakangungu rakau ki te COM pera i te Whakaahua 7 me te 8.


Topology Whatunga
- All BACnet MS/TP networks should be wired in a true “daisy-chain” configuration.
- BACnet MS/TP network best practices dictate that the MAC ad-dressing of the nodes on the network should be sequential with the physical location of the units. For exampe, ki te ko te pouara te kōpuku tuatahi i runga i te whatunga, me whai i te wahitau MAC iti rawa. Ko te waahanga e whai ake nei i runga i te mekameka daisy me whai wahitau MAC kotahi tau teitei ake, aha atu.
Whakapapa me te Polarity
- He mea nui te papa whenua kia pai ai te whakahaere o te waeine ME te mahi whakawhitiwhiti BAS tika.
- There is not one standard ground resistance threshold that is recognised by all agencies.
- However, the NFPA (National Fire Protection Association) and IEEE have recommended a ground resistance value of 5.0 ohms or less. The NEC has stated: “Make sure that system impedance to
- ground is less than 25 ohms specified in NEC 250.56.” In facilities with sensitive equipment, it should be 5.0 ohms or less. The telecommunications industry has often used 5.0 ohms or less as its value for grounding and bonding.
- If you suspect you may have grounding issues at a facility, specialised earth grounding testers are used by qualified electrical contractors to test for correct grounding.
- In addition, control power polarity should be maintained throughout the BAS network AND communication wiring polarity should be maintained as well. Per the recommendations in the Open Controller Network Wiring Guide regarding the PROT485, shield wires should NOT be grounded to any earth ground or to the controller’s power ground. The PROT485 and the individual control-lers allow the shield to float a limited amount so that there are no ground loops. If the voltage i runga i te whakangungu rakau ka nui rawa atu ki te whenua o te whenua, katahi ka nui atu te voltagka whakaheke toto ki nga taputapu whakamarumaru i runga i te PROT485, i runga ranei i nga kaiwhakahaere.
Wehenga Paeke
- Ko te puranga BACnet e whakamahia ana me te hua SystemVu KORE e tautoko ana i te wehewehenga paatete.
- Me whakaweto te wehewehenga i runga i nga taputapu tuatoru.
- Please be aware that the segmentation feature is NOT required for the current BTL (BACnet Testing Laboratories) certification.
i-Vu Integration Tips – Source Files me nga Rerekētanga Putanga
- The current SystemVu products are compatible with i-Vu versions 7.0 and later. Older versions of i-Vu software may not work cor-rectly with current SystemVu products.
- Me whakauru nga papanga i-Vu katoa i te wa e hono ana ki nga hua SystemVu. Ka taea te tiki mai i te waahanga "Tikiake Mana" o HVACPartners, mai i nga Mana Kawe webwāhanga pūmanawa pae.
- He maha nga wa e tika ana ki te taapiri a-ringa i te puna SystemVu files to the i-Vu server and place them into the appropriate folder.
- Kia mahara ko te puna files kei runga HVACPartners (Kei raro i te TUPAPA TAUTOKO > POST SALE SUPPORT > SOFTWARE SERVICE).
COV (Huringa o te Uara) me nga Pouara Tuatoru
- Ko te ahua COV i BACnet MS/TP e whakamahia nuitia ana e etahi kaihoko tuatoru.
- Heoi, he iti noa nga tohu COV e tautoko ana a SystemVu. Ko nga tono pouara mo nga tohu COV kaore i te tautokohia e te punaha SystemVu ka arahi ki nga hapa whatunga me te ngoikore o te mahi whatunga.
- Ko te whakaweto i te mahi COV i roto i nga taputapu-tuatoru ka taea te awhina i te wa e raru ana nga take hokohoko whatunga.
- Ko etahi waahi mahi, kaihoko ranei ka tono kia whakamahia te waahanga COV.
- Mena koinei te take, ka whakaatuhia e te Ripanga 2 nga tohu COV tika e tautokohia ana e te kaiwhakahaere SystemVu.

APDU Timing, Polling Rates, etc. with Third-Party Routers
- Ehara i te mea rereke te hiahia ki te whakatika i te maha o nga tautuhinga pouara e tino rerekee ana i ia mahi ki ia mahi.
- Kia aroha mai, karekau he uara "whakaturia ki roto i te kohatu" e mahi ana ki ia mahi.
- Kia mohio koe ko etahi o enei uara kei roto ko nga reiti waahi APDU, reiti pooti, me nga reiti waahi NPDU.
- In general, longer polling rates for BACnet objects are to be preferred (polling too frequently increases bus traffic). Polling/refresh rates should not be set below every 30 seconds. It is best to keep the polling/refresh rates between 1 and 5 minutes. In general, the recommendations in Othe APN022 application tip regarding read and write rates should be observed.
- It is a best practice to set timeout rates, such as APDU timeout rates at the highest timeout rate of any device on the network. Many devices default at 3000 milliseconds. SystemVu is defaulted to 6000ms and cannot be changed. When applying SystemVu controls on a BACnet bus with other devices, all devices should be set to match SystemVu at 6000ms. The SystemVu APDU segment length is fixed at 480 bytes. Since the BACnet stack used for SystemVu controllers does NOT support packet segmentation, some third-party routers may need to have the APDU segment size or RPM “chunking” or “bin packing” algorithms mare manually adjusted to properly work with features such as Read Property Multiples.
Reiti Tāpare me nga Pouara Tuatoru
- Many third-party vendors default their router “MS/TP Max Info Frames” value to “100”. This is too high for SystemVu nodes – a value of “20” will provide a more stable network.
- All legacy production SystemVu software versions have the “Max Info Frames” value default to “10”. Older versions defaulted to “1” which can cause network issues. If a network with an older SystemVu
- units is experiencing issues; upgrading to current production software is recommended.
- Ko nga waahanga hanga A2L o naianei he reiti anga ka taea te whakarite me nga uara rangatira.

Steps to Connect SystemVu and ZS Sensor Over Rnet Port
- Each ZS Sensor connected via the Rnet port must have a unique address, but addresses do not have to be sequential.
- Open the hinged cover on the sensor enclosure, and then use the DIP switches to set an address from 0 to 14. (1 is factory default.) Each DIP switch has the value shown in Figure 15 below. Turn on as many DIP switches as you need so that their total value equals the address.
EXAMPLE: DIP switches 1 and 4 below are on. Their values (1 + 8) total 9, so the sensor’s address is 9.
- . Connect the SystemVu Controller and Zone Sensor over the Rnet Port as shown in Fig. 16-17.
- On SystemVu User Interface, navigate to SETTINGS / NET-WORK SETTINGS / ZS SENSOR CFG and set the ZS Sen-sor address (see Fig. 18).
- SystemVu supports up to 5 Zone Sensors which can be connected over Rnet Port (see Fig. 19).
- Please note that there is a 500mA VA limit for the Rnet plug. Check the total VA consumption of the sensors prior to connecting them to the SystemVu board.

LED Tūnga Kākāriki
- The SystemVu controller has one Green LED. This LED (indicates Local Equipment Network) should always be blinking whenever power is ON. If LENLED is not blinking, check LEN connection for
- potential communication errors (MBB J15, J16, J17, and J2 on the Display).
- LED Tūnga Kōwhai
- Yellow LED is used to indicate Building Automated Systems (BAS) communication activity. The LED will blink when the MBB transmits a message on the BACnet bus.
TE WHAKAMAHI I TE RANGATIRATANGA BACNET MS/TP
BACnet MS/TP Whirihoranga
- SystemVu can use the BACnet MS/TP protocol for communications. This section in the document contains Carrier’s recommendations for configuring and wiring an MS/TP network that will provide the best network performance with Carrier controllers. However, Carrier controllers will work on any BACnet-compliant MS/TP network. Controllers can communicate on an MS/TP network at 9600 bps, 19.2 kbps, 38.4 kbps, 57.6 kbps, 76.8 kbps, or 115.2 kbps.
- For configuring SystemVu BACnet Baud Rate, navigate to the menu below in the user interface and select the Baud Rate. UI Menu > SETTINGS / NETWORK SETTINGS / BACNET
- Kia mahara ki taua puna files e hiahiatia ana mo te kimi tika i nga waeine SystemVu e te punaha i-Vu. Puna files are included in cumulative patches, OR can be manually imported into i-Vu. Source files and the process for importing them are located on HVACPartners.
i-Vu MODSTAT
- For additional debugging on iVu systems, use the MODSTA T command in i-Vu which, when requested, will trigger the System Software Information along with BACnet Firmware version as shown in the images below.
- Select the Controller listed under Router (see Fig. 21).
- Right click and select the MODSTAT (Module Status) command. (see Fig. 22). A new Pop up window will come with the list of Controller Software and BACnet firmware versions as shown in Fig. 23.

Kaiwhakahaere Whakatau
- Each SystemVu controller on the MS/TP network must have a unique BACnet MS/TP MAC address, which is set by the User In-terface Menu. Valid addresses are 1-99.
- BACnet MS/TP network best practices dictate that the MAC ad-dressing of the nodes on the network should be sequential with th e physical location of the units. I.E. If the router is the first node on the
- network, it should have the lowest MAC address. The next unit on the daisy-chain should have a MAC address one number higher, etc.
Nga aratohu raruraru
- Ki te kore e kitea he kaiwhakahaere SystemVu i runga i te whatunga MS/TP, tirohia nga tautuhinga whirihoranga katoa penei i te Reiti Baud, te wahitau MAC me nga tautuhinga Kawa BAS. I nga whatunga i-Vu, tirohia te puna files
- have been manually imported.
- NOTE: Use the same polarity throughout the network. Also, use a 120-ohm resistor at each end of the network.
- Network troubleshooting needs to be deliberate and sequential. In the event of rolling communication failures or no communications at all, the best approach is to start with the physical layer, then
- progress to the network layer, and finally the application layer.
Paparanga Tinana
- The use of an oscilloscope as described in the Open Controller Network Wiring guide is always the first step. If your wave-forms are not clean, packet collisions will occur, which will cause losses of communication. Waveforms should look similar to the one shown in Fig. 24, NOT like the distorted (noisy ) waveform shown in Fig. 25.

- He maha nga mea ka paheke te ahua ngaru i runga i te paparanga tinana. He kino te akuaku o nga waea, nga waahanga waea kua pakaru, kua pakaru nga iahiko whakawhiti RS-485 i runga i nga papa takitahi, me te pokanoa hiko mai i nga taiao "haruru" he iti noa nga take ka taea e te katoa te whai waahi ki te korikori paparanga tinana. Ko te wehe i nga waahanga o te waahanga whatunga ma te wehewehe i te pahi korero kia haurua, ahakoa he hoha, ko te tikanga pai rawa atu hei wehe i nga hapa o te paparanga tinana.
- Please note that collisions caused by incorrect network software settings can also lead to distorted waveforms. While not as common as physical layer defects, this should be taken into consideration – see section addressing the network layer.
- Manatokohia kei te whakamahia te waea tika me te hono tika ki ia taputapu me te pouara. Me noho nga parenga whakamutu i te timatanga me te mutunga o ia wahanga pahi. Me whakarite kia kore e whakamahia nga parenga rītaha whatunga i te mea kua rītaha kē a SystemVu i te rohe. Ko enei mea nga take e kitea ana i te wa e rapurongoa ana.
Apa Whatunga
- Once any physical layer issues are resolved, the next step is to analyse the network layer. The use of network bus traffic monitoring tools is very valuable when trying to isolate network problems. There are a number of tools available, such as Wireshark®1, which allows the diagnosis of issues such as COV over polling, APDU timing, duplicate MAC addresses, etc.
- The most common network layer issues are with APDU timeout, BACnet point writes, COV increments, and segmentation settings. SystemVu products are hard-set to a 6000ms APDU timeout; all devices on the same bus should be set to 6000ms for best results. COV should be disabled unless clearly being used. If COV is being used, ensure the refresh increments are set so that COV requests do not occur too frequently. The goal should be for COV requests to occur no more often than every 60 seconds. Ensure BACnet writes/refresh or broadcast rates are reasonable and not occurring too frequently. Usually, point writes should not be greater than once per minute. Lastly, ensure packet segmentation is disabled on the network bus.
PAHA TONO
- I runga ano i te pouara e whakamahia ana, i te wa kua whakatauhia te paparanga tinana me nga take paparanga whatunga, ka taea e te rangahau taipitopito o nga whakaoho me nga matohi kei runga i te pouara te whakaatu i te wa, te puna. file, me nga take rorohiko.
