Hi guys,  i have an old Accurite 5  made by bausch and lomb  will the scales interface with your system ? looks to have 6 pin din type plugs for the glass scales

thanks,

Joe

Joe,
It depend on what the protocol is. Do you have user manual of any kind?

Thank you

im sorry but i dont.. this thing is ancient.. probably 30 - 40 years old

It's unlikely it will work, then. Back then there was no standard and I haven't see many quadrature scales from that era.

well,  i found the scales on acu-rite.com

its a 6 pin system

a     square wave signal
b     square wave signal in quadrature
       (90 degree nominal phase relationship) with channel "A" signal
c      vcc, +5.1 plus /minus .1 Vdc ,current 200ma max
d      common ( power supply and signal return )
e      shield, reading head case ground
f       fiducial trigger output signal ( when provided )

its called a A-R/5 10um .0005" resolution scale assembly

here is a link to the manual

(06-14-2018, 03:52 AM)re: AR-5s: these are standard quadrature glass scales. Used these exact scales circa 1980 on two machines w/ quadrature firmware in June 2018.  I found the a and b outputs to be open collector with 680 ohm pullups, despite documentation to the contrary. Thus a simple 1k ohm pulldown at MSP inputs was perfect to do a level shift of 5v scale VCC  to 3.2v for safe input to MSP. (Your AR-5 may be different...measure and verify.)  Operating with no issues. Wrote: [quote pid='1221' dateline='1528604889']

Abeabe,

not so good at electronics.. so u are saying i can ad a 1k ohm resistor to the 5 volt line and it will be ok ?

thanks for your patience !

and thats exciting news !!!   My old accurite readout is the size of a small microwave !!!

One resistor to ground at A and B inputs at MSP.

And I clearly do not know how to get a jpg inserted into post. Try this way...

Abeabe,

thank you so much !  i will be ordering the box in the next week or so and will follow up with my progress !!
