Escient DVDN-552 user manual RS-232 Connections

RS-232 CONNECTIONS

External disc changers are controlled via two-way serial protocols using RS-232 serial cables. You should use COM ports 1 - 5 for each external disc changer.

COM port 6 is to be used for connecting an Escient ETP-1500 wired touch panel or to interface with a third party control system such as AMX or Crestron.

Note: You should use the Ethernet control system for controlling FireBall from a third party control system whenever possible. Using the Ethernet control system frees up COM port 6 for other purposes, allows much longer distances between FireBall and the control system, and provides a much faster path for data transfer.

IR CONNECTIONS

The direct IR input jack on the back panel of the FireBall is for controlling FireBall from a wired IR distribution system such as a Xantech system. This connection must be an IR signal with a 36kHz carrier using an 1/8” mono or stereo connector.

The IR input jack provides 12V power. This means that you can directly connect a 12V IR receiver (like the Xantech series 291 units) to the FireBall using a 1/8” stereo connector.
