Introduction
At some customer sites, one or more timeclocks are installed at a location that is
remote from the host computer. At such sites, modems must be used to establish
communications over telephone lines between the eTIME and the timeclock(s).
The ADP 14.4Kbps modem option is a V.32bis, 14.4Kbps, RS-485 modem that may
be installed within one timeclock at the remote site. This remote installation allows
the timeclock (and all other timeclocks in the RS-485 network) to communicate
with the host over telephone lines. The V.32bis protocol provides two-wire, full
duplex, and fall-back capability to other industry-standard modem protocols with
speeds other than 14.4Kbps.
The 14.4Kbps Modem option is compatible with timeclocks equipped with the
following:
!
Main boards with a part number of 6600177-00X or 6600186-00X (Rev. A or
later)
!
Boot-PROM software version 2B00 or later for the #6600177-00X board or
3B00 or later for the 6600186-00X board
!
FLASH-EEPROM time and attendance application version 400.5C or later
The figure that follows illustrates a eTIME computer communicating over phone
lines with a timeclock. The timeclock is configured for RS-485 serial
communications, equipped with an internal 14.4Kbps Modem option and
programmed to use that option.
