COMPUTER CONTROL

If the dedicated program is installed, your personal computer can be connected with the COM jack of the VC-H1, then the VC-H1 can be easily controlled via the computer. For details, contact your authorized KENWOOD dealer, customer service, or service center.

You can also connect a computer to the DATA port of the VC-H1 in order to control the VC-H1 via the computer. This, however, asks you to manually send ST commands to the VC-H1 through the computer.

Note: Pin 1 of the connector, which mates with the VC-H1 DATA port, can be identified with a triangle mark on the connector. Pin 1 is located just below the mark.
