This add-on board lets our Platino board read out up to four digital calipers and comes in very handy when you want to upgrade your lathe or milling machine with a digital position-output. The add-on board contains buffers/converters, a multiplexer and the connectors for linking to the calipers. The Platino LCD displays the real-time measurements of all the calipers connected to the system, thus presenting a way to monitor movements on machines with limited head travel or excursion.
But pay attention: there is no standard as such for the protocol the digital calipers use. The software we provide is programmed to use the following bitstream from the calipers:
X,B,B,B, B,B,B,B, B,B,B,B, B,B,B,B, X,X,X,X, X,S,X,X,
where X’s are don’t care bits, B's indicate a binary number with the least significant bit at the start of the string and S is the sign bit.
