OSDP Reader Configuration for Azure IC2/IC4/RI2M

This article below will guide you to add and configure OSDP readers to Azure IC2/IC4/RI2M. 

Wiring Reader into IC2/IC4

  • If wiring the readers into the IC2/IC4 board COM1/2 ports directly, the readers need to be configured differently from the factory default.
  • Since the readers will be sharing the same serial bus as downstream devices, they will need to be configured with 115200 Baud Rate, OSDP address that does not conflict with any other downstream devices that are on that same port and default OSDP encryption.


Wiring Reader into RI2Ms

  • RI2Ms have a separate bus for OSDP readers, and by default they are hardcoded to 9600 Baud rate by Azure.
  • Each reader port resides on it’s own serial bus, so they will not conflict with each other.
  • Currently the RI2M will only support 1 OSDP reader per reader port.

Configuration OSDP Reader in UnityIS

  • In UnityIS, change the device type to OSDP Reader. 
  • Next set the OSDP Address Mask to the OSDP address of the reader. 


For IC2 Only

  • When a reader is configured for OSDP, you can wire the OSDP reader directly into the reader port.
  • Reader 1 must be wired to COM1 or to Reader Port 1.
  • Reader 2 must be wired to COM2 or Reader Port 2.
  • You can only wire 1 reader into the reader port.
  • Here is an illustration of wiring it directly to the reader port of an IC2. 


For IC4 Only

  • When a reader is configured for OSDP, it must be wired into the COM ports.
  • The IC4 does not support redirect via the reader ports.
  • Reader 1/3 must be wired into COM1.
  • Reader 2/4 must be wired into COM2.
  • With the IC4, there are separate connects for T+,T-,R+,R-. To make this work, you must jump the T+ with R+ and the T- with R-.
  • Here is an illustration of the wiring for OSDP readers on the IC4. 


For RI2M Only

When wiring readers into the RI2M, wire them directly into the reader ports. The readers need to be configured for 9600 baud rate. For wiring, please refer to the illustration above for the IC2.


Here are some example configurations:

IC2 and (1) RI2M with 4 OSDP readers.

RI2M = OSDP address 4, 115200 baud rate, wired into COM1.

  • IC2 Reader 1 = OSDP, 115200 Baud rate, Address 0, Default OSDP Encryption – Wired into IC2 Reader Port 1 or COM1.
  • IC2 Reader 2 = OSDP, 115200 Baud rate, Address 0, Default OSDP Encryption – Wired into IC2 Reader Port 2 or COM2.
  • RI2M Reader 1 = OSDP, 9600 Baud rate, Address 0, Default OSDP Encryption – wired to RI2M Reader Port 1.
  • RI2M Reader 2 = OSDP, 9600 Baud rate, Address 0, Default OSDP Encryption – wired to RI2M Reader Port 2.


IC4 and (1) RI2M with 6 OSDP readers.

RI2M = OSDP address 4, 115200 baud rate, wired into COM1.

  • IC4 Reader 1 = OSDP, 115200 Baud rate, Address 0, Default OSDP Encryption – Wired into COM1.
  • IC4 Reader 2 = OSDP, 115200 Baud rate, Address 0, Default OSDP Encryption – Wired into COM2.
  • IC4 Reader 3 = OSDP, 115200 Baud rate, Address 1, Default OSDP Encryption – Wired into COM1.
  • IC4 Reader 4 = OSDP, 115200 Baud rate, Address 1, Default OSDP Encryption – Wired into COM2.
  • RI2M Reader 1 = OSDP, 9600 Baud rate, Address 0, Default OSDP Encryption – wired to RI2M Reader Port 1.
  • RI2M Reader 2 = OSDP, 9600 Baud rate, Address 0, Default OSDP Encryption – wired to RI2M Reader Port 2.
