Plus-X GSC Adapter

Upgrade your GSC or VRC without Rewiring

Upgrading legacy GSC and VRC systems is faster and more affordable than ever. The Plus-X GSC Adapter connects to up to two GSC/VRC wiring interfaces and command relays using the same DB37 cables as the legacy remote control. Not a single channel needs to be rewired to upgrade to the ARC Plus Touch, saving hours of work.

Cost Effective Upgrade

The Plus-X GSC Adapter includes all the I/O needed for up to 16 channels, eliminating the need for additional input and output units.

With its 256 channel capacity and Ethernet I/O architecture, a single ARC Plus can replace multiple GSC300 or VRC2500 systems. Simply install a Plus-X GSC Adapter at each site.
