Varitext clock

[Ghostrider]

Hi srob,

The clock will likely be a Varitext clock. They work with RS232, 485, 422 and 20mA current loop. The protocol is called TIMC - T:HH:MM:SSOWD:MM:YY CR/LF (0D0Ah)

H= Hrs, M=mins, S=secs, DOW = day of week 0 being Sunday, D = day of month, M = month, Y= year This is transmitted at 1200baud as i remember! But the clock is configurable for anything from 300baud to 9600baud. Some also work with just the time info part (T:HH:MM:SS)

PM me and i can send you the test software (as DOS based tool) that will send the clock time data a from PC.

Cheers,

Steve.
