Configuring Mercury LP1502, LP4502, MR50-S3, and MR52-S3 controllers to use two OSDP readers per port - Synergis Softwire 11.4.3

Starting in Synergis™ Softwire 11.3.1 and Security Center 5.10.4.0, Mercury LP1502, LP4502, MR50-S3, and MR52-S3 controllers support two OSDP readers per port through a setting configured in the Synergis™ Appliance Portal.

1. In the Synergis™ Appliance Portal, enable the Two OSDP readers per reader port option on the Mercury controller settings page.
   NOTE: When this option is enabled, the Smart card option configured on the OSDP reader in Config Tool is on by default, and remains on in the background, even if you turn off the option.
2. Restart Synergis Softwire.
3. Add two OSDP readers to the reader port of the Mercury controller:
   1. From the Config Tool homepage, open the Access control task, and click the Roles and units view.
   2. From the entity tree, select the Synergis™ unit, and click the Peripherals tab.
   3. Double-click Reader 1, and configure the following settings:

      Type of reader

      Select OSDP 2.

      Baud rate

      Select a bit rate.

      Address

      Select the address you configured for the first reader.

   4. Click Save.
   5. Double-click Reader 1 Out, and select the address you configured for the second reader.
      NOTE: Only the address needs to be configured because Reader 1 and Reader 1 Out use the same configuration, except the address.
4. Assign the readers to a door.
   Example: Reader 1 and Reader 1 Out must be set on the same door, and Reader 2 and Reader 2 Out must be set on the same door.
5. If the controller has a second reader port, you can repeat step 3 to configure Reader 2 and Reader 2 Out on the second port.
