Note 1: Voltage is developed across a 100Ω resistor on the 5 V line in
the transceiver. When 2 mA flows, approximately 4.8 V is developed.
Note 2: A 10 µF capacitor is not required in the following cases:
• When other equipment has DC blocking capacitors.
• When a 2-terminal electret condenser microphone is used.
PC
To connect the transceiver to a PC in order to manage
the memory channels in the transceiver, use the PG-4Y
PC interface cable. You will also need the supported
software to manage the memory channel contents of the
transceiver. To download the software, access the
following URL:
http://www.kenwood.com/i/products/info/amateur.htm.
To use the software, access Menu No. 31 and select
“ON” {page 107}.
For your reference, the following diagram shows how
the transceiver communicates to the PC using a serial
(COM) port.
