LSSI-RS232 LightSync Digital AV Interface for RS-232LSSI-RS232 LightSync Digital AV Interface for RS-232

LightSync AV Interface for RS-232

Model: LSSI-RS232

The LightSync Serial AV Interface for RS-232 (LSSI-RS232) can be added to any LightLEEDer panel to provide LightSync input control from any audio visual system using a RS-232 connection and ASCII commands.  With this interface the AV system can trigger a set of LightSync inputs to emulate an ILC switch stations. This provides On and Off relay actions, control of dimming outputs and reads status of pilots and photocell levels.
