Features:
- Combines Link Controller electronics with the documented Group 2 personality module.
- Provides one four-wire RS-485 or RS-422 serial communication port.
- Requires the corresponding SLC algorithm in the Ovation controller.
The current ordering configuration is
1C31166G01 + 1C31169G02, the Ovation Link Controller Electronics and Group 2 RS-485/RS-422 Personality Module Pair documented for Ovation I/O paired assembly.
In the intended system role, the assembly provides one four-wire RS-485/RS-422 serial port for communication between Ovation and supported external equipment. Operation requires the appropriate SLC algorithm in the controller.
For selection and commissioning, confirm protocol implementation, baud rate, addressing, termination, biasing, cable shielding and the installed SLC configuration before replacement. Prove the serial link with control outputs inhibited.
Availability is subject to Apter Power inventory and sourcing confirmation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Exchanges serial data between Ovation and a supported third-party device, for its documented operating duty.
- Provides a four-wire industrial communication path for legacy plant equipment, through the intended receiving-system interface.
- Supports service of an installed SLC position retaining its Group 2 termination design, in the configured and commissioned installation.
- One four-wire differential serial port serves the external equipment link, within the documented field or network interface.
- Transmit and receive pairs are routed separately through the Group 2 personality module, between the assigned communication endpoints.
- Shielding, termination and bias follow the engineered RS-485 or RS-422 topology, before the complete path is placed in service.
- The appropriate SLC algorithm must be loaded in the Ovation controller, through the documented engineering or controller workflow.
- Protocol framing, baud rate and device addresses follow the external equipment specification, for the installed channel or external device.
- A validated configuration backup is restored before the link is placed in service, before the restored configuration is returned to service.
- Control consequences are inhibited while serial messages and addressing are tested, under the site's controlled work procedure.
- Isolation and grounding follow the site communication and cabinet standards, for the complete installed loop or enclosure.
- Only approved protocol mappings are enabled for control or protection use, before the system is released for operation.
