Chapter 5: PIXCOMW
Introduction
PIXCOMW is a software and hardware option that synchronizes the date
and time for the PIX-3000x Series Electronic Time Recorder. This
software requires an IBM (or compatible PC) running DOS version 3.3 or
higher, EGA or better display, two serial ports and a modem. An
asynchronous multi-point line driver is needed to interface the computer
with the PIX-3000x's (Recommended: LD485A-MP). PIXCOMW allows
time/date information obtained from either the user or ACTS* to be sent
out from up to 4 serial ports. When communicating to the PIX-3000x's,
each unit will be disabled from performing other functions for a period
ranging from one to three seconds.
