Communication Port Pin Assignments

The COM 1 and COM 2 ports can be switched between typical RS232 or
RS232 with power on its Pin NO.1 (12V) and Pin No.9 (5V).
COM 1/COM 2 (RS232 with power/422/485)
The system is also equipped with 3 display ports: DVI-D, HDMI, and VGA.
DC-in
VGA
Notes:
1. The DVI-D port can be in HDMI or DVI-D.
2. The HDMI is a DP/HDMI combo port but can only transmit HDMI signals (unless wired as a DP
port). Please plug in an HDMI cable with the right orientation and alignment to avoid damage to
the connector. You should feel resistance (due to a pin on the right) if the cable is not inserted
correctly. Please see a video at https://youtu.be/SUj07rfN5l8 for detailed instructions.
