I bought a 2nd hand navico TP5000 tiller pilot. Unfortunately there is
no user manual to it.
I think it is not too hard to handle but there might be some tricks
that could be handy in using and installing it.
Also I would like to know if there is anyone who has experience in
connecting it to a NAVCOM T500 GPS device through NMEA 0183. E.G. what
connectors are used (what is the pinconfiguration of the TP 5000?

Any information is welcome

Thanks Jos

Navico TP5000 NMEA wiring:

12 Vdc negative is blue
12 Vdc positive is brown

NMEA common: Yellow/green;
NMEA Data: black

NMEA via RS232:

The standard RS-232 connector is a 25 conductor DB-25, although
many units now use a 9 pin DE-9 which is different from a DB-9.

Serial Port Connections
Computer (DTE) Modem
DB-25 DE-9 Signal Direction DB-25
2 3 Tx Data - 2
3 2 Rx Data - 3
4 7 Request to send - 4
5 8 Clear to send - 5
6 6 Data Set Ready - 6
7 5 signal ground 7
8 1 Data CarrierDetect - 8
20 4 Data Terminal Ready - 20
22 9 Ring Indicator - 22

For NMEA-0183 you are only concerned with Rx data, the signal ground
(and possibly Tx Data, if we want the Navico to talk to the GPS)

I believe the European standard is 4800 baud for this type of
equipment. You may have to play with that a little.

Have fun.
