DAC-NET Digital Audio Card
Instruction Manual
DAC-NET Digital Audio Card
The Model DAC-NET from Siemens Industry, Inc. is the CAN-BUS master for all CAN modules. One DACNET is required in each control panel and each transponder. It is the source point for eight digital audio channels and communicates audio data via ASIBUS to all digital audio cards.
There is one BACnet (Building Automation & Control Network) interface. It communicates all instructions and messages directly with the PMI/PMI-2/PMI-3 (CPC-DAC interface).
It provides network communication (D-NET) between control panels and transponders (nodes). The network can be wired either Class B or Class X. EachDAC-NET occupies one D-NET address. The DACNET contains various on board tones and audio messages.
The DAC-NET can contain an optional LPB (Local Page Board) which has to be mounted piggyback. This CAN module has a fixed CAN address (100) and provides two inputs. One is for the microphone located at the LVM and the other connects the internal telephone system. Additionally, the LPB provides one output for the monitor speaker located at the LVM. For more information refer to the LPB Installation Instructions, P/N 315-035200 / A24205-A334-B836.
The D-NET is supervised for open, short and ground fault. Each D-NET input / output is electrically isolated. Wiring can be either Class B or Class X with unshielded twisted pair. The maximum distance between two DAC-NETs is 300m with cat3 cable, 900m with cat5 cable or 700m with cable 1pr.
18B FPLR / 1pr. 16B FPLR / 1pr. 14B FPLR. A maximum wiring length can be up to 10 km throughout the entire network with a maximum of 32 DAC-NET nodes. Up to 99 CAN sub-modules are addressable. The system is able to handle eight independent audio channels. Software updates for µC and D-NET controller are downloadable. Tones and audio messages are downloadable. Diagnostic LEDs for troubleshooting are located on the front panel of the DAC-NET. Refer to Figure 1.
OPERATION
Each DAC-NET occupies one card slot in the CC-5/CC-2 card cage. Only the left connector of the CC-5/CC-2 contains the signals to the CPC-DAC interface. The connection from the PMI/PMI-2/PMI-3 to the CC-5/CC-2, in which the DAC-NET is mounted, must be on the left side of the CC-5/CC-2.
D-NET
The D-NET Main In / Return Out and Main Out / Return In are isolated from each other and from the DAC-NET. This allows the use of different power sources with different ground references. The DAC-NET is able to detect ground faults and data faults of each D-NET section. Each DAC-NET sends and receives a data stream consisting of digital audio stream and control data. The baud rate is 1.536 Mbps.
NOTE:
Class B/Style 4 = ULC DCLB
Class X/Style 7 = ULC DCLC
Class B
The node with the lowest node number (master) sends the data stream from Main Out to Main In at the next node. The last node combines Main In with Return Out and returns the data stream back. When the data stream comes back to the node with the lowest node number this node combines Return In with Main Out and sends it to Main In of the next node.
Figure 2 DAC-NET D-NET Class B
In a Class B configuration, two unshielded twisted pairs are required. They can be in one cable.
Class X
In a Class X configuration, the master sends the data stream by using Main Out / Main In in a loop. The Return Out / Return In loop contains only a test data stream for supervision.
Figure 3 DAC-NET D-NET Class X
Class X Fault Status
If there is a fault in the Main loop, the node before the fault point combines Main In with Return Out. The node after the fault point combines Return In with Main Out. Both loops are combined and the net is still running. In this situation there is no test data stream. After repair D-NET reconfigures automatically. If there is a fault in the Return loop the failure of the test data stream will be detected and notified.
Figure 4 DAC-NET D-NET Class X Fault Status
In Class X configuration, two unshielded twisted pairs between the nodes are required. The connection between Node 1 and Node 32 must be in a separate cable and must not share a conduit with any other cable.
Controls and Indicators
The front panel of the DAC-NET contains one reset switch and seven LED for the DAC-NET, and one D-NET address switch and four LEDs for the DNET.
For the optionally mounted LPB, there is one reset switch and eight LEDs as shown in Figure
A reset switch is located on the top of the front panel. Pushing the reset switch re-initializes the DAC-NET operation.
The LEDs follow the reset switch. Their functions are defined as follows:

PRE-INSTALLATION
The following components must be set prior to inserting the card into the CC-5/CC-2:
S4, Test Switch: These switches select programming and test functions. All switches must be set to the OFF position.
S6, Network Address Switch: Set the three-digit D-NET address for the DAC-NET using the three position switch located near the bottom of the front panel. (Refer to Figure 1 for the location of the switch.) The address at the DAC-NET front panel must be the same as the address selected in the Zeus Programming Tool. To increment each digit of the address, press the “+” button above the desired digit; to decrement each digit, press the “-“ button below the desired digit. The range of allowable network addresses is from 0 to 9 (left digit) and allowable node addresses is from 1 to 32 (two right digits).

Figure 7 DAC-NET Class X (ULC DCLC) D-NET Wiring
Each connection between two nodes has to be installed in separate cable routes.
All CAN cards and modules must be combined via CAN Bus. The CAN Bus requires a 120 Ohm termination resistor on both ends. Use a CAN terminator at CAN connectors and a termination resistor at screw terminals to fulfill it. They are shipped with DAC-NET. See Figures 9-14.
All digital audio cards and modules must be connected via the ASI-Bus (LPB, AIC, ZAC-40, ZAM-180, XDMC). The ASI-Bus consists of 4 pairs (Part of CC5). They require four 120 Ohm termination resistors on both ends. Use an ASI terminator at 60-pin connectors to fulfill it. They are shipped with DAC-NET. See Figures 9-14.The PMI/PMI-2/PMI-3 provides ASI termination at one end when used.
The Analog Audio Bus includes three audio signals with a level of 0dBu/+6dBu (LVM microphone, LVM monitor speaker, FMT Phone). The LPB supervises the microphone signal wiring. The supervision requires an EOL resistor 3.3K. The EOL resistor is integrated in the LVM.
If one LVM is mounted, the jumper P7 must be set in position 1 – 2.
LVM default factory setting: Jumper P7 in position 1 – 2
Connecting The Internal CAN, ASI And Analog Audio Bus
CAN BUS
Install the CAN cable into P3 of the CC-5/CC-2 or into P2 of the OCM-16 / SIM-16.
Install the other end of the CAN cable into the first CAN module on the inner door.
Observe the location of the CAN termination devices. Install a CAN terminator in the last CAN module on the inner door. Install the 120 Ohm CAN termination resistor into TB1 10 and 11 on the PSC-12.
ASI BUS with PMI/PMI-2/PMI-3
Install the 60-pin cable into P1 of the CC-5/CC-2.
Install the other end of the 60-pin cable into the PMI on the inner door. There is no need to install an ASI terminator at the PMI/PMI-2/PMI-3. The PMI/PMI-2/PMI-3 has it already inside. Install an ASI terminator into the 60-pin connector on the PSC-12.
Analog Audio BUS
Install the Analog Audio cable into the 10-pin connector of the PMI/PMI2/PMI-3.
Install the other end of the Analog Audio cable into one 10-pin connector of the LVM.
If there is a FMT install a further Analog Audio cable into the second 10-pin connector of the LVM and the other end into the FMT.
The DAC-NET must be installed into any open slot of the CC-5/CC-2 which is connected at the left side with the PMI/PMI-2/PMI-3.
Anti-Interference Capactitor:
It is a 6.8µF / 100V bipolar capacitor. In every Voice system must be one Anti Interference Capacititor.
It has to be connected between Ground and Earth. This capacitor is necessary to eliminate noise on the speaker lines.
