Serial Ports - COM 1/2
The Q data radios feature a 9 pin miniature D-Shell (DE-9) Female connector that supports two individual serial port
connections. Each serial port is associated with an embedded serial terminal server that provides the serial to TCP/IP or UDP/
IP connectivity.
• COM 1 uses pins 2, 3, 7 & 8 with pin 5 as the common ground.
• COM 2 uses pins 4 & 6 with pin 5 as the common ground.
• An RSSI output is available on pin 9 which is useful for antenna alignment.
Pin out specs
(1) Pin 2, 6 & 8 are outputs rated at +/- 6v, 65mA max.
(2) Pin 3, 4 & 7 are inputs rated at +/- 15v, 5mA max.
(3) Pin 9 is an analog voltage output to indicate the radio’s live RSSI measurement.
(4) Connecting wires should be #22 AWG (0.33mm
2
) or larger.
