The Model 1109A Cat 5 Control Bridge provides an access point for control systems to use the AVAtrix Cat 5 infrastructure, reducing wire, installation labor and programming code. There are two main applications for the 1109A: controlling TVs (on/off, change inputs, etc) and switching/controlling sources. These applications can be used independently or together, for each zone, upstream and/or downstream from the 1109A. IR jacks are isolated from all other system wiring and can therefore be used for any kind of low speed signal suited for Category 5 cable conductors. The Model 1109A is compatible with all of dual Cat 5 zone receivers, including Models 9878, 9879 and 9880. Each Cat 5 receiver IR pathway operates independently, so one pathway could be set up for in-coming IR signals and another pathway in the same system could be set up for out-going IR signals.
