Connections
Drawings of the connection cables can be found below.
Control-RRC:
Connect the Remoterig Y5c or a standard RS-232 cable between the PC and the RRC
COM2.
The microphone can be connected direct to the RRC AUX/MIC connector if you have a
microphone with RJ-45 connector. If you have a microphone with a circular connector you
can use the Remotrig Y5a cable, the ADMY-817, from Yaesu or make one by yourself.
The speaker is connected direct to the RRC SP-jack with a 3.5 mm stereo plug.
Radio-RRC:
From the RRCCOM2 connector to the radios CAT connector (D-sub RS-232) you can use
the Remoterig Y6c cable or make a cable by yourself (drawings are provided). The smaller
radios in the FT-8x7 series do not have a D-sub or RS-232 port; they only have a TTL-port
accessible via a mini-DIN jack. You can either buy an adapter cable, D-sub to mini-DIN,
with a level converter called CT-62 from Yaesu or you can make a cable by yourself and
connect it to the RRC TTL connector.
Between the RRC AUX/MIC connector and the radios microphone jack you can connect a
standard patch cable if the radio have a RJ-45 jack. If the radio have a circular
microphone jack you can use the Remoterig Y6a cable or make an adapter cable by
yourself (drawings are provided). If you make the cable by yourself, just cut a standard
FTP (screened) patch cable and solder an 8-pin circular connector on it. Make the cable as
short as possible to prevent it from picking up HF.
The speaker signal from the radios external speaker jack to the RRC SP jack is connected
via a standard “off- the-shelf” cable with 3.5 mm stereo plugs in both ends.
