the other devices being integrated. The connections include: RS-232, RS-485, VIANet,
Relay, Sense Input, IR Output, External IR Input, Audio Outputs, Component Video Inputs
and Outputs, Ethernet, USB and IR Link connections.

RS-232 Connections

These connections are used to integrate with RS-232 controlled devices to provide control
and feedback and to allow RS-232 commands to trigger Event Maps. Use of RJ45 to DB9
adapters is generally required for connections to RS-232 controlled devices.
As shown in Figure 3-1, the HC4 has four RS-232 ports and the HC8 has eight RS-232
ports. Ports 1 and 2 have full hand-shaking capabilities and ports 3 and up have partial
hand-shaking.
