Serial Connector – COM1
COM1 provides +5v on pin 9 when enabled. Only COM1 should be used to connect an external scanner to the
Thor VX8.
The serial connector, with a (1) label, (configured as COM1) is industry-standard RS-232. The connector includes a PC/AT
standard 9–pin “D” male connector. The VMT Manager controls the function of pin 9. Pin 9 is capable of supplying +5 VDC for
an external bar code scanner. Refer to VMT Manager for more information on configuring pin 9.
