serial connectivity depends on cables
In the manual they list the following cables, either 7inch or 25inch (under accessories):
-
GN-PC
PC Serial -> Pump To Computer -
GN-NET
Pump To Computer -> Pump To Network -
GN-TTL
Pump to Pump reciprocating cable (for TTL synchronisation)
The first two cables are the ones that works in a serial setup. If one looks into the coloured pins on the cables:
- one end
Yellow-Green-Red-Black
- opposite end
Black-Red-Green-Yellow
(inverted)
The order is inverted as it swaps receiver/sender ports on the microcontroller in a serial connection.
The cables that wear a plastic tag “CBL-DUAL-3” will be needed in case one needs to synchronise TTL and they will not work in the jacks "To Computer” / “To Network”. If you check the colours:
- one end
Empty-Yellow-Green-Red
- opposite end
Black-Red-Green-Yellow
