COMPUTER
The COM connector allows you to directly connect a computer or dumb terminal by using an RS-232C cable
terminated with a female 9-pin connector.
No external hardware interface is required between your computer and the transceiver. See “APPENDIX” on page 70
for information related to this connector.
COMPATIBLE TRANSCEIVER
When transferring data to or from another TS-570 or the TS-870S, directly connect the two transceivers using the COM
connectors.
When transferring data to other KENWOOD transceivers, use the optional IF-232C interface unit. Connect the
IF-232C to the ACC 1 connector located on the compatible transceiver. 6-pin DIN plugs (E07-0654-XX) are available
as options. Contact your dealer or a KENWOOD Service Center.
