as an installer... hahaha
usually the ptc units come with the adapter cable
lemme see what i can pull up for ya
from ptc manual

1. Check the manuals
for the Icom and the PTC-IIpro for the pin locations on the
connectors! They do not necessarily agree with the pin numbers of the connector that
you might buy, depending on that connector's ancestry. The colors shown above are for
the pigtail cable supplied with the PTC-IIpro. Check the colors with an ohmmeter, errors
2. The German-style DIN connector has a different physical pin geometry, and is not
interchaneable with the US-style DIN connector used by Icom. Label the cable ends to
avoid any confusion over which end goes where.
3. The PTC-IIpro has provision for an alternate 12V input on its HF audio connector. This
provides a convenient way to connect power to the modem, but if the cable is particularly
long then this could be a source of RF interference
. Consider a separate power connection

control cable for M802 radio via AirMail and PTC-IIpro:.
PTC-IIpro: Remote frequency-control is optional, but highly recommended when a PTCIIpro
modem is used with an Icom M802 transceiver. This connection uses the PTCIIpro's
remote connection to the radio's "REMOTE" jack (a standard RS232
Find the pigtail connector that came with your SCS PTC-IIpro that has the din connector
that fits into the "HF Transceiver Control" port on the back of the PTC-IIpro. On the
other end solder an 9 pin D connector as follows:

* A careful reader of the Icom M802 user manual will observe that the documentation
is in error
with respect to the direction of data flow on these pins in RS232 mode (oddly they are correctly
labeled for NMEA
mode). The M802 service
manual schematic is correct. Use the above
connections; they work.
Be careful to insulate the other wires coming out of the PTC-IIpro pigtail. You can
destroy your PTC-IIpro if they get shorted to one another or to ground. Put a ferrite on
both ends, as usual for all of your interconnect wires.
this cable from the "HF Transceiver Control" jack on the PTC-IIpro to the "Remote"
jack on the Icom M802.
Direct COM-port connection:
The M-802's "REMOTE" connector is a standard 9-pin serial
connector which can be
directly connected to a computer serial port with a standard 9-pin male/female serial
extension cable. So if you have a SCS PTC-IIe or a PTC-II that does not have a RS232
output, you can directly control the M802 with another serial port on your computer. This
may require you to add another serial port using a USB/RS232 adapter.
hope that helps
