DESIGN AND APPLICATION
MCX2D is an I/O expander dedicated to the RACS 5 system. The device, after connection to the MC16 access controller and the MCT series terminals, enables to control of 2 doors. The expander offers I/Os and distributes the power supply and the RS485 communication bus. The expander operates with a backup battery, which,,h depending on particular requirement, can be charged with 0.3A, 0.6A, or 0.9A current. The expander is equipped with removable terminal blocks, which facilitate electrical connections during installation and maintenance. MCX2D expander is offered separately as an electronic module for installation in a metal housing with a power supply or as a part of MC16-PAC-2-KIT.

Characteristics

• RACS 5 system I/O expander
• Power supply distribution for door devices
• RS485 bus distribution for MCT terminals
• 4 parametric (EOL) inputs
• 4 transistor outputs
• 6 power supply outputs
• Backup battery charging
• RS485 interface
• Removable screw terminals

Power supply
The expander requires a 13.8VDC power supply, and it is recommended to apply a PS2D power supply unit for that purpose. Due to the relatively high current between the expander and the PSU, all connections should be made using short cables with adequate cross sections. PSxD series PSUs (Roger) are offered with two 30cm/1mm² cables dedicated to supply the expander. Multiple MCX2D expanders can be supplied from the same PSU, and in such a case, each connection must be made with an individual pair of cables. When the expander’s supply voltage is too low, the battery cannot be fully charged, and when the voltage is too high, the battery can be damaged. MCX2D, which is supplied from a PSU equipped with its own backup (e.g., UPS), can be supplied with 12VDC, but then it cannot be equipped with its own backup battery.

Fig. 1 Two MCX2D expanders supplied from the same PSU

Backup battery
MCX2D enables battery charging with 0.3A, 0.6A, or 0.9A current up to the level of voltage supplied to the expander (nominal 13.8VDC). The current is selected with jumpers (fig. 2). When the battery voltage drops to approximately 10V, it is disconnected from the expander. The battery is reconnected when the 13.8V supply to the expander is restored. To ensure battery charging up to 80% level within 24h (according to EN 60839 standard) following current settings must be applied:

• 300mA for 7Ah battery
• 600mA for 17Ah battery
• 900mA for 24Ah battery

RS485 interface

• MCX2D is an addressable device connected to the RS485 communication bus of the MC16 controller. At the same time, the expander distributes the bus to MCT terminals at each door. The expander can be operated with the default ID=100 address, or it can be assigned with an address in the range of 101-115. All devices on the RS485 bus of the MC16 controller, including MCX expanders and MCT terminals, must have unique addresses in the range of 100-115. MCX2D is addressed during low-level configuration by means of the RogerVDM software or manually during the memory reset procedure.
• In most cases, communication works with any cable type (standard telephone cable, shielded or unshielded twisted pair, etc.), but the recommended cable is unshielded twisted pair (U/UTP cat 5). Shielded cables should be limited to installations subject to strong electromagnetic interference The RS485 communication standard used in the RACS 5 system guarantees proper communication a distances of up to 1200 meters,, as well as high resistance to interference If the expander and controller are powered by separate power supplies, it is necessary to short-circuit the expander’s power supply minus (GND) with the controller’s power supply minus (GND) using a separate wire of any small cross-section.

LED indicators
Expanders are equipped with LED indicators, which are used to signal integral functions. According to further mentioned procedures, the service mode is started by restarting the expander and placing a jumper on the MEM contacts.

Inputs
Expander offers DC and DR parametric inputs of NO, NC, 3EOL/DW/NO, and 3EOL/DW/NC type. Input types and electric parameters, such as response time and parametric resistors, are defined within the low-level configuration (VISO v2 or RogerVDM). Input functions are assigned within the high-level configuration (VISO). Multiple functions can be assigned to the same input at the same time. In the standard scenario of door control, DC inputs are dedicated to the connection of door contacts, while DR inputs are dedicated to the connection of exit buttons, and they do not require low-level configuration as they can be operated with default settings:

• DC inputs: NC type / 50ms response time
• DR inputs: NO type / 50ms response time

Table 2. Input types

• NO input can be in a normal or triggered state. In the normal state, CA contacts are opened. Input triggering is caused by CA contacts closing.
• NC input can be in a normal or triggered state. In the normal state, CA contacts are closed. Input triggering is caused by CA contacts opening.

• 3EOL/DW/NO input is operated in such a way that CA contacts closing is interpreted as triggering of the first input, while CB closing is interpreted as triggering of the second input. In the VISO software DW input type is represented by two independent inputs. Each can be used for a different purpose and assigned with different function.

• 3EOL/DW/NC input is operated in such wa way that CA contacts opening is interpreted as triggering of the first input, while CB opening is interpreted as triggering of the second input. Inthe the VISO software DW input type is represented by two independent inputs. Each can be used for a different purpose and assigned with different function.

Parametric resistors
The same values of parametric resistors are used for all inputs, i.e,. 1kΩ; 1,2kΩ; 1,5kΩ; 1,8kΩ; 2,2kΩ; 2,7kΩ; 3,3kΩ; 3,9kΩ; 4,7kΩ; 5,6kΩ; 6,8kΩ; 8,2kΩ; 10kΩ; 12kΩ. In case of 3EOL/DW (Double Wiring) input type, Alarm A resistor defines a value of resistor used to detect triggering of the first input, while Alarm B resistor defines a value of resistor used to detect triggering of the second input. Alarm A resistor value must differ from the value of Alarm B resistor at least by three positions in the list above. The total resistance of the wire used to connect the contacts to the input should not exceed 100 Ω. Default values of parametric resistors:

• Alarm A = 2,2 kΩ
• Alarm B = 5,6 kΩ
• Tamper = 1,0 kΩ

Response time
The response time parameter defines the minimal impulse time on the input that triggers the output. Each input can be configured individually in a range of 50 to 5000 ms within low-level configuration (VISO v2 or RogerVDM).

Transistor outputs
Expander offers LCK and BELL transistor outputs. Electric parameters such as polarity are configured in n the low-level configuration (VISO v2 or RogerVDM). Functions are assigned to outputs within the high-level configuration (VISO). Multiple functions with different priorities can be assigned to the same output at the same time. In the standard scenario of door control, LCK outputs are dedicated to control door locks, while BELL outputs are dedicated to control alarm signalling devices and/or door bells. In the standard scenario of operation, both LCK and BELL outputs do not require low-level configuration.

Power supply outputs
Expander offers 6 outputs in order to provide power supply to athe access controller, terminals, door lock, and other external devices.

VDR outputs
VDR power supply output is dedicated to supplying the door lock, alarm signalling device, and other door-related devices. The terminal VDR+ is protected with a 1.0A electronic fuse. The terminal VDR is internally shorted to ground (GND). The green LED indicator is located at the VDR+ terminal to signal the voltage at the output.

TML outputs
TML’s power supply output is dedicated to supplying readers at the door. The terminal TML+ is protected with a 0.2A electronic fuse. The terminal TML is internally shorted to ground. The green LED indicator is located at the TML+ terminal to signal the voltage at the output.

VOUT outpuThe t
The OUT power supply output is dedicated to supplying additional electronic modules, and it can also be used to supply the connected access controller. The terminal VOUT+ is protected with a 0.2A electronic fuse.. The terminal VOUT- is internally shorted to ground. The green LED indicator is located at the VOUT+ terminal to signal the voltage at the output.

• Note: If the MC16 access controller is supplied from the expander, then it cannot be supplied at the same time by its own PSU, and it cannot operate with its own backup battery.

AUX output. 
AUX power supply output is dedicated to supplying optional electronic modules. The terminal AUX+ is protected with a 0.2A electronic fuse. The terminal AUX- is internally shorted to ground. The green LED indicator is located at the AUX+ terminal to signal the voltage at the output.

 INSTALLATION

The expander should be installed in a metal enclosure with a door and a power supply. The enclosure must be earthed by means of PE wire. The manufacturer offers a range of enclosures designed for electronic modules and equipped with power supplies. The installation site should be away from heat and moisture sources and protected from unauthorized access. The connection between the power supply and the expander should be made using a cable with a minimum cross-section of 0.5 mm² and a length of up to 50 cm. The PSxD series power supply comes with cables with a cross-section of 1 mm² and a length of 30 cm, which can be used to power the expander. All electrical lines connected to the expander must run inside the building. All electrical connections should be made with the power off. The network circuit supplying the device must be equipped with an installation switch.. After completing installation and start-up, close the enclosure.

• Installation may only be performed by a qualified person with the appropriate permits and authorizations for connecting and intervening in 230VAC and low-voltage networks. It is not permitted to use the enclosure without a properly installed and technically functional electric shock protection circuit (PE).

OPERATION SCENARIOS

In a typical scenario of operation, MCX2D expanders are used in MC16-PAC-2-KIT two-door access control kits (fig. 4 and 6). In the alternative scenario of operation, multiple MCX2D expanders are connected to multidoor MC16 access controller (fig. 5). In such scenario the maximal number of expanders operated by MC16 controller depends on its type and it is limited by available range of addresses ID=100-115 on RS485 bus of MC16 controller where all MCX and MCT devices must have unique addresses. For example, in the case of read-in/out doors, it is possible to control max. 6 doors in such a setup as MC16-PAC-6 + 3 x MCX2D + 12 x MC, T, while in the case of read-in doors, it is possible to control max. 10 doors in such setup as MC16-PAC-10 + 5 x MCX2D + 10 x MCT. In both cases, 15 addresses on the RS485 bus are occupied. It is also possible to mix read-in and read-in/out doors within a single MC16 controller if the limitation related to the number of RS485 addresses is preserved.
