The Serial Port component represents the RS-232 serial connection pins on the rear of the Q-SYS Core. The connector varies depending on the hardware.

3-pin Euro

Pin	Description
TX	Transmit pin. Connect this pin to the RX (receive) pin on the other device.
RX	Receive pin. Connect this pin to the TX (transmit) pin on the other device.
Ground	Earth ground reference.

3-pin Euro: NV-32-H (Core Capable)

Note: On the NV-32-H (Core Capable), the RS-232 and GPIO IN pins share a 5-pin Euro connector. You can use both connection types simultaneously.

Pin	Description
TX	Transmit pin. Connect this pin to the RX (receive) pin on the other device.
RX	Receive pin. Connect this pin to the TX (transmit) pin on the other device.
Ground	Earth ground reference for GPIO input and RS-232 connections.

Male DE-9

Pin	Description
2	RX (Receive)
3	TX (Transmit)
4	(I/O-22 only) Provides +5.5VDC @ 70mA
5	GND (Signal Ground)

Note: All other pins on a Core are not supported.

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.

Input Pins

This component has no output pins.

Output Pins

Serial Port

Connect this pin to the Serial Input pin of a Q-SYS scripting component, such as Block Controller, Text Controller, or Control Script. You must configure these components for serial communication.

The Serial Port component has no specific configurable properties.

Tip: For additional properties not listed, refer to the Properties Panel help topic for more information.

TX Bytes

Displays a running total of the number of bytes sent.

RX Bytes

Displays a running total of the number of bytes received.

Reset

Resets both TX Bytes and RX Bytes to zero.
