Setting the physical address of DDS RS-485 controllers

2024-11-01Last updated

All JET or TPL door controllers that are either connected to the same RS-485 channel or found on the same LAN must use different physical addresses.

What you should know

The physical address must be a value from 0 - 31, and is set using the DIP switches on the DDS controller. The DIP switches are labeled differently, depending on the model of the controller:
  • For TPL controllers, the physical address is set with the DS2/1 and JP4/1 - 5 DIP switches.
    Note:
    If you have a TCP/IP extension board attached to the TPL controller, you must remove it to access the DIP switches.
  • For JET controllers, the physical address is set with the DS1/1 - 5 DIP switches.
The reader communication protocol is set using the JP4/6 - 8 DIP switches on TPL controllers and the DS1/6 - 8 DIP switches on JET controllers. For example, for Wiegand to read up to 50 bits without parity check on a TPL controller, set JP4/7 to 1 or ON. For more information, see the documentation from DDS corresponding to your specific device.

Procedure

  1. For TPL controllers, set DS2/1 to 1 or ON.
  2. Set the physical address on the JP4/1 - 5 or DS1/1 - 5 DIP switches, according to the following tables:
    DIP switch settings for changing the physical address on DDS controllers.

Example

To set the physical address of a TPL controller to 15, set DS2/1 to ON and JP4/1 - 5 to ON ON ON ON OFF, respectively.

To set the physical address of a JET controller to 16, set DS1/1 - 5 to OFF OFF OFF OFF ON, respectively.
