2.4 Extending Module Connection

The 2N IP Style functions can be extended by connecting any of the available 2N IP Verso extending modules via the VBUS connector. Choose the proper accessories for each type of extending module installation.

• 125 kHz RFID card reader
• 13.56 MHz NFC RFID card reader
• Secured 13.56 MHz NFC RFID card reader
• Induction loop
• Fingerprint scanner
• Wiegand module
• OSDP module
• I/O Module

Module Bus Interconnection

All the extending modules, except for the tamper switch, are interconnected via a bus. The bus starts on the basic unit and goes over all the modules. The order of modules on the bus is irrelevant. And it also irrelevant which bus connector on the module is used as the input and which is used as the output.

The modules include a 220 mm long interconnecting cable, the Wiegand (9155037) and I/O (9155034) modules include an 80 mm long bus cable.

It is possible to order separate bus cables of the length of 1 m, 3 m or 5 m (Part No. 9155050/9155054/9155055 respectively), which are intended for remote module installations. Typically, they help install an RFID card reader on the opposite side of the wall on which 2N IP Style is installed. This cable may only be used once on the bus. The total length of all the bus cables used in these extended installations may not exceed 7 m.

Module Power Supply

All the 2N IP Style modules, except for the tamper switch, are powered from a bus. The available bus power output depends on the power supply type. The basic unit can use a 4A power supply to increase the power available to the modules connected.

Wiegand Module

The Wiegand module (Part No. 9155037) is one of the 2N IP Verso system elements and is used for connecting an external Wiegand device (RFID card reader, fingerprint / biometric data scanner) and/or connecting the intercom to an external security exchange. All the inputs and outputs are galvanically isolated from the intercom with the insulation strength of 500 V DC. It is necessary to feed +U IN on Wiegand OUT from the Control Panel.

Installation Procedure

Having connected the OSDP module to 2N IP Style via the VBUS, connect the OSDP device to the module. The OSDP module uses the RS-485 bus for the interface.

Connect the OSDP device as instructed (A to B or B to A) keeping the correct order to avoid malfunction.

Having logged in to the 2N IP Style web interface, use the HW / Extending Modules menu to set the following:

• Give the module a user identification (optional).
• Choose a group for access data resending, making sure that the settings are identical with those of the access readers from which the data are to be resent (card ID< PIN).
• The settings of the codes to be transmitted are optional.
• Enter the OSDP address between 0 and 126 to set the OSDP module address on the OSDP line.
• Set the communication rate in accordance with the requirements of the device to be connected.
• Enter your own encryption key into 2N IP Style and the opponent’s device to ensure encrypted communication.
• Enable forced encryption just for encrypted communication.

Any unencrypted communication from the OSDP device will be rejected if forced encryption is enabled.

If the OSDP device enables remote encryption key setting on a peripheral, you can use the installation mode. Once the encryption key is received, the common mode is automatically switched on. The installation mode is signaled by a LED fast blinking on the OSDP module.
