FS8700-108 – GE-TLC

CAS Driver



( GE Total Lighting Control)



This serial driver allows connectivity to a GE-TLC network by providing data transfer to the RLINK device. The RLINK device is provided by GE Lighting Controls as a gateway between its proprietary network and building automation networks. Thus to provide data transfer between a 3rd party protocol such as BACNet, it is necessary to connect the BACnet network to the RLINK by means of a FieldServer.

The driver may be configured as a client or server. The Client functionality is fully documented and supported. The FieldServer cannot be used as a substitute for the RLINK device – for this reason the server side functionality is not documented. If you are interested using the server side please contact the sales group.

As a client the driver is capable of :

polling for status data,

sending commands to operate the relays,

sending commands as if a PSS switch had been operated,

receiving unsolicited status messages from the TLC network.


The driver can be configured as a BACnet adapter – a device which reads a predefined data set and automatically make its available as a set of BACnet data objects. More information is available on request.

The driver can support a simultaneous connection for a PC running TLC configuration software such as WinControl. More information is available on request. This feature has limitations documented in the manual. If you intend to use this feature you must understand the limitations before making your purchase.

Fieldserver Mode Nodes Comments
Client 9999 Only one RLINK device may be connected to a single port on the FieldServer. However, each RLINK device may form part of a network of Lighting Panels (nodes). 

The driver does not limit the number of nodes that may be polled via the RLINK.

Unsupported Functions and Data Types

Function Reason
It is possible that the RLINK device could send additional unsolicited messages. The published protocol does not identify additional messages but it is possible that future RLINK/TLC network firmware may have additional messages.
