Caution
•
When the JP2 and JP3 jumpers are mounted, strong pull-up / pull-down resistors
(560 ohm) are connected to the RS-485 bus. These jumpers must be mounted /
unmounted together, i.e. you cannot mount just one of them. The strong pull-up /
pull-down resistors can be connected only and exclusively to one arbitrary device
on the OSDP bus.
•
When the JP4 jumper is mounted, a 120 ohm termination resistor is placed
between the A and B wires of the OSDP bus. The termination resistors can be
connected exclusively to the first and last OSDP bus modules. We recommend that
these resistors are connected to the first and last modules.
Having logged in to the 2N
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
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.
Tamper Switch Module
The Tamper switch module (Part No. 9155038) is one of the 2N
helps secure the system against tampering.
•
The module contains two switches, which open whenever the front frame is removed:
•
One switch leads directly to the terminal board and is connected to an external
security exchange (32 V DC / 50 mA max).
•
In coordination with the I/O module (9155034) or Wiegand module (9155037), the
other switch can be used for initiating alarm via the Automation interface in the
®
2N
IP Style configuration.
•
This module is not connected to the bus.
