RS-232 Serial Port Component

The RS-232 Serial Port component allows you to make a connection to the RS-232 connector on a Core, I/O Frame, or the I/O-22 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.

Inputs

RS-232 Serial Port - Serial port data to and from the RS-232 connector on the Core, I/O Frame or the I/O-22.

Outputs

Serial Port - Connects to the Control Script, Command Buttons, and Scriptable Controls components.

RS-232 Details

Pinout

This signal to DE-9 configuration is known as DTE. All 9-pin D-Shell RS-232 pinned as DTE have this configuration. All PC serial ports are DTE as is the Core, I/O-Frame and I/O-22. Usually peripherals are DCE, which reverses the receive and transmit pins, allowing a straight-thru cable to be used.

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. For custom terminated DE-9 connectors, pins 2 and 3 may need to be swapped on one end of the cable. In any case, a TX pin on one end MUST be connected to an RX pin on the other and vise-versa for data to flow properly.
