LANG - 3000 is the network gateway which provides the interface
between the DLPRO 3000 host control console and the TC - 3000
programmable time clock. The LANG can also function as a
clock, perfoming local control of a relay and integral DC asher as
programmed. Each LANG - 3000 can accommodate up to six distinct
groups of time clocks with up to twenty clocks in each group. Each
group of clocks connected through the LANG can have a unique
weekly schedule, holiday schedule and exceptions. The TC - 3000’s
within each group are typically programmed from the host computer
using the DLPRO 3000 software; however the program schedules may
also be programmed manually at the LANG using the integral keypad
and display and sent to the clocks in each group. Program elements
are opened by typing the appropriate access sequence and a key word
for each entry is displayed to guide the user through the programming
process. Once the required information is entered for each eld, the
display advances to the next eld until all data for that program element
is entered. The LANG - 3000 provides ‘type-over’, ‘back up’ and ‘eld
skip’ features during the entry process to facilitate error correction,
simplify navigation and make programming quick and easy. Program
schedules can be reviewed or edited at any time without disturbing the
operation of the LANG.
The LANG - 3000 maintains time and date during power outages a
minimum of 7 days with its rechargeable capacitive backup system.
Program information is stored in non-volatile memory (NVRAM)
and is kept during power off conditions for the life of the unit. When
installed and communication with the host system is established, time
and date are updated by the host computer during system monitoring
or when sync command is used. When communications are down or
operating in stand-alone mode, a real-time clock maintains time and
date information with a quartz crystal accuracy of two seconds per
month.
Technical information, programming functions, and operating
parameters concerning the LANG - 3000 can be found in Section 7—
Appendix (pages 31–32).

gateway.
