encoder help

[gv71]

I was wondering if someone could help me with the 4 wires from the encoder. on the board there are holes 1 thru 5 hole 5 not occupied, hole 1 is red wire hole 2 is white hole 3 is green and hole 4 is black then there is 5 prongs from the optical sensor soldered to the board and they are marked B, VCC, A , NC , GND, if I follow the path on the board red wire goes to B, white wire goes to VCC, green wire goes to A, and black wire goes to GND and I am using gecko 340s I also have a pittman servo with a HEDS 5310 encoder with a ribbon type connector can I replace the ribbon connector with something else or should I get an adapter for it from some place. Thanks!

I am not sure of your question, you seem to have identified the wires ok, If you don't have any info on the encoder, and in the fact there does not seem to be any identifyable electronics on board, you may have to hook it up initially with 5v and see what the results are on A & B, hopefully it will be squared up and not a sinewave output. As regards transitioning a ribbon cable, usually you can split the ribbon conductors and solder almost any kind of connector on, rather than replace the ribbon which generally goes to a ribbon header in the encoder.

Hi
The encoder you mention is a single ended TTL encoder.
red is vcc +5 v
Black is Gnd
White is A out put
Green is B out put
the 5 th pin is for a C dirive which is not connected

you will need some pull up resistors on A & B to sink the current to your diver
