Also_where_can_I_get_a_few_regular_TTL_encoders>
I_have_not_seen_that_many_on_ebay_with_the_right_shaft_size_or_configuration?

US Digital do reasonably priced encoders or look on eBay.
 Your Daito encoder  sounds like it should work but possibly the A and B are not TTL, maybe sine wave? What is the code number on the encoder?

I_dont_think_it_is_TTL,Have_found_a_few_on_cheap_motors_on_ebay_today_they_are_on_the_way_but_the_model_of_the_encoder_is_DTRE-PWZK.

I looked earlier on Google for your encoders and came up a blank, obviously never had the code but still I couldnt find any info on any Daito encoders, so knowing the code probably wont change that.
 Do you have a scope? If you do then you could easily find out what the outputs of the encoder are.

Hi, GaryV

Colors of wires, terminal markings, picture of encoder, any aditional Info would Help.

Thanks, Chip

Hi, GaryV

You mat need pul-up resistors, Ref to Picture.

Thanks, Chip
