(PC programming interface cable: Option)
The KPG-46/46A is required to interface the transceiver to
the computer. It has a circuit in its D-sub connector (KPG-46:
25-pin, KPG-46A: 9-pin) case that converts the RS-232C logic
level to the TTL level.
The KPG-46/46A connects the MIC connector of the trans-
ceiver to the computers RS-232C serial port.
5-4. KCT-53U description (USB adapter: Option)
The KCT-53U is a cable which connects the KPG-46A to a
USB port on a computer.
When using the KCT-53U, install the supplied CD-ROM
(with driver software) in the computer. The KCT-53U driver
runs under Windows 2000 or XP.
5-5. Programming software KPG-102D description
