Serial Port (I/O-8 Flex, DCIO/DCIO-H)
The RS-232 Serial Port component allows you to make a connection to the RS-232 connector on a I/O-8 Flex for Lua Scripting. When a connection is made, and an appropriate Lua script written, you can control and read from devices such as DVD players, recording hardware, video, lighting, and so on. Connections are made through a three-position Euro-style connector.
Inputs
RS-232 Serial Port - Serial port data to and from the RS-232 connector on the I/O-8 Flex, DCIO, or DCIO-H.
Outputs
Serial Port - Connects to the Control Script, Command Buttons, and Text Controller components. These components must be configured for Serial Port input.

Pinout
You must check the pinout of any equipment, including the cable, to be connected to a Q-SYS serial port for input or output. Many times in serial troubleshooting, problems may be solved by inserting a "null-modem" adapter or cable to swap the TX and RX pin positions. The TX pin on one end MUST be connected to an RX pin on the other and vise-verse for data to flow properly. |
