Interface modules come in all shapes and sizes and offer a wide range of features. Synergis™ Softwire supports most of the common features found on the market.

Synergis™ Softwire 11.2 supports the following Mercury controller features.
The following is the legend for some common values found in the Supported column:
Feature is offered by the interface module and is supported by Synergis™ Softwire.
Feature is offered by the interface module but is not supported by Synergis™ Softwire.
Not applicable
Feature is not offered by the interface module.

1 Encryption is mandatory with Synergis™ Softwire 10.2 and later.

2 The OSDP (Secure Channel) reader must be paired to a reader port on the controller. The certified readers are: HID multiCLASS SE RP40, Allegion aptiQ MT15-485, and Nexus Cidron SC9100-MD-MP-VG2. Other models might also work.

3 There is not always a one-to-one match between an offline log entry and a Security Center event. Mercury controllers are limited to 50,000 offline log entries.

4 The credential limit of the default configuration. Up to eight different credential lengths are supported.

5 There are two values that limit the number of controllers you can connect to the appliance:
  • The maximum number of controllers you can connect to the appliance
  • The maximum number of controlled readers

For Synergis™ Cloud Link, SV-32, SV-100, and SV-300 the maximum number of Mercury controllers and controlled readers are 16 and 128 in Security Center 5.4 and earlier, and 32 and 256 in Security Center 5.5 and later.

Also, each Mercury controller is limited in the number of Mercury access control readers (ACRs) it supports. EP1501 and LP1501 controllers support up to 17 ACRs. For other EP or LP controllers, the limit is 64. The formula for per-controller ACR count is:
  • One ACR per door with at least one Reader.
  • One ACR per door with at least one Door monitor input
  • One ACR per door with at least one Door lock output
  • Two ACRs per door with two Readers (Card-in/Card-out)
  • One ACR per elevator with one Reader.

6 Requires Security Center 5.10 or later. Applies to LP2500, EP2500, LP4502, and EP4502. LP1501, EP1501, LP1502, and EP1502 support up to 250,000. M5-IC and MS-ICS support up to 560,000.

7 Degraded mode in this context does not refer to Mercury's degraded mode where the downstream panel is disconnected from the Mercury controller. Mercury's degraded mode is not supported.
