With a Yaesu it is a little more complicated. The Yaesu CAT system uses three wires and they have
different connectors and pin wiring arrangements between different models. Older Yaesu radios require
the rig control TTL (5 volt) to RS232 level converter built into the
RIGblaster pro
.
For an older Yaesu CAT system you must set the
RIGblaster pro
rig control jumper P16 to Yaesu. You
must also change the plug on one end of a patch cord to match the Yaesu DIN jack. You must make sure
that the tip of our plug comes from the data out of your radio and the Ring goes to the data in to your
radio. West Mountain Radio has two CAT Cables available for Yaesu radios.
Older Kenwood radios that have provisions for TTL control are not possible to control with a
RIGblaster pro
. These Kenwood radios utilize what is referred to as Negative TTL Logic and are not
compatible with the Positive Logic employed in the
RIGblaster pro
TTL to RS232 converter. Positive
logic, as employed in most computer interface circuitry, represents a logical one with a positive voltage
and a logical zero with a zero voltage.
To connect a
RIGblaster pro
to Yaesu radios with a 6 pin DIN receptacle with TTL level CAT control,
the following cable would have to be constructed. We have found pin numbers vary from Yaesu model
to model but GND is usually numbered pin 1.
If you have a Yaesu or other brand of radio with an RS232 Rig/CAT control jack you should not use our
rig control output. You may use the
RIGblaster pro
's RXD & TXD on A passed through to B option (#9
on the P16 Jumper block). This will allow both sound card operation, PTT, CW and rig control with a
single serial port with software such as HamScope, MixW or WriteLog. If you wish to use separate
sound card and rig control programs at the same time you will have to make a direct connection from
your computer to the radio's RS232 control jack. If the radio is equipped with a FEMALE DB-9 RS232
connector for Computer Control (CAT), the following cable will be necessary from the B Port on the
RIGblaster pro
to the radio RS232 DB-9. Both DB-9 connectors shown here are MALE connectors.
If you have a newer Kenwood (Example TS-570/870/2000) radio or an Icom IC-7800 with a MALE
RS232 CAT/Rig Control jack you should not use the CTL IN/OUT jack on the
RIGblaster pro
. You
may use the
RIGblaster pro
for both sound card operation, PTT, CW and FSK To do CAT on these
