TinyGate - User's manual and assembly instructions
We have also to set the mode FIF232 (IF232), therefore it’s necessary to set the
SJ10 solder bridge to pos. 2-3 as follows:
CAT / CI-V Mode Jumper setting (SJ10)
Pos.
SJ10
CAT Interface Mode
1-2
CI-V (default)
2-3
FIF232, IF232, Elecraft
The jack socket X3 allows a direct connection with a ELECRAFT transceiver
which support the CAT, with the help of a simple audio cable with two 3.5mm-
stereo Jack plugs.
CAT / CI-V power supply
The TinyGate has a very flexible interface, which allows it to be adapted to a wide
range of transceivers.
To ensure the galvanic isolation of the CAT / CI-V port, an external power supply
is necessary (8-15VDC). This may for example be directly take from the
transceiver. See also
Connection cable to the transceiver
If an external power supply isn’t available directly from the
transceiver, so it’s possible to use the
X1 (CW / FSK) socket to
connect an external power supply. One should thus remove-cut
the copper trace on SJ1 and add a wire jumper between pin 3 and
pin 5 on the socket JP1.
The power supply to the CAT / CI-V port may be chosen as internal (from the
USB) or external:
