j"Com Transceiver Control
Computer Interface
Model: TC-I TC-K TC-Y TC-Y2
The J-Com Transceiver Control Computer Interface allows you
to control most if not all of radio functions from your computer. It
is functionally identical to the Icom CT-17, Yaesu FIF-232C,
Ten Tec 305 and Heath computer interfaces. It will work with all
radios and rig control software which use these interfaces.
• No external power supply ...power is ‘lifted’ right from the
computer’s COMM port!
• RFI proof ...all electronics are enclosed in a shielded DB-25
connector hood.
• Fully hardware and software compatible...will work with any
software including DXBase, LOGic, K1EA's CT program,
Turbolog, RC-plus and many others.
• Fully wired and tested...just plug it in and go.
• Great for winning contests and making contacts easier than
before.

INTRODUCTION:
The J-Com Transceiver Control Computer Interface provides the
appropriate “level shift” of signals between your computer’s RS-232 COMM
port and your transceiver’s TTL computer control connection. By using low
power integrated circuit devices to make these conversions, we have been
able to package the entire interface into the shielded hood of a DB25 type
RS-232 connector. Because only 3.5 - 6 mA of current is required, the
interface is able to “borrow” power from the computer for its operation.
