Configuring and adding secure I/O modules in the Synergis™ Appliance Portal

2025-12-16Last updated

To add secure I/O modules to a Synergis™ unit, configure the I/O modules using the Synergis™ Appliance Portal.

Before you begin

Create an OSDP channel with Programming mode enabled.

What you should know

  • Ensure that each I/O module connected to the same RS-485 channel is assigned a unique address.
  • When Programming mode is enabled, you can only have one I/O module connected to the RS-485 channel at a time.
  • When connecting I/O modules in a daisy chain, ensure that all I/O modules share the same bit rate.
Best Practice:
Adding multiple secure I/O modules on the same RS-485 channel increases latency. Install an end-of-line termination resistor on the last module in the RS-485 chain to prevent communication collisions.

Procedure

  1. From the hardware tree, select the secure I/O module you added while creating the OSDP channel and then click Edit ().
    The properties dialog box opens.
  2. Enter the physical address you want to set for the module.
    Note:
    If you are using the phg I/O module, you can enable the Ignore tamper option to suppress tamper inputs. For more information, see Configuring phg secure I/O modules to ignore tamper events.
    OSDP properties of the phg secure I/O module in the Synergis Appliance Portal.
  3. Click Save.
  4. Connect and power up the I/O module.
    The configured bit rate and physical address are sent to the module, which comes online after accepting them.
  5. Repeat steps 1 - 4 for the remaining I/O modules.
  6. From the hardware tree, select the OSDP channel and click Edit (), then clear the Programming mode checkbox that you selected while creating the channel.
  7. Add the configured I/O modules:
    1. At the top of the Address column, click Add ().
    2. In the Add hardware dialog box, click Add to add the I/O modules at the addresses you have programmed.
  8. Click Save.
