4-12: Restart Button
The restart button is used to restart the N-1000-III/IV microprocessor. (See Figure
4-11.) Press the restart button to restart a “locked-up” control panel and to activate
a change made to any DIP switch setting (for baud rate and/or panel address).
The panel’s self-test feature can be activated by setting all of the DIP switches to
the On position and then depressing the Restart button. For details of the self-test,
refer to Appendix C: Troubling Shooting.
Pressing the Restart button DOES NOT alter N-1000-III/IV database memory. The
data base can be completely cleared by the following method: Disconnect the AC
power and battery back-up. Move jumper JP9 to position JP10 for one minute
then return it to JP9. Restore the power connections.
4-13: RAM Chip
Control panel RAM chips store all database and transaction buffer memory. The
N-1000-III/IV control panels use a single RAM chip with the option of an addi-
tional chip in socket U6. The N-1000-III/IV-X control panels come equipped with
an extra RAM chip. (See Figure 4-11.)
NOTE:
Control panel card database and transaction buffer capacities are deter-
mined by the number of RAM chips used and can be modified by use of the U
command I option. Refer to Appendix A: Programming Quick Reference Guide
for details.
4-14: PROM Chip
The control panel PROM chips store all N-1000-III/IV program and control logic
memory and are located in sockets U5 & U19. (See Figure 4-11.) On each PROM
is a sticker which indicates the socket number and the firmware version of the
chip. Refer to the main PROM number when referencing the N-1000-III/IV
Programming Manual for specific programming/operation functions.
4-15: Additional Installation Information
Northern Computers recommends the following installation techniques for the
N-1000 panels:
DO
•
Do run all wiring for door locks/strikes and panel primary power in a sepa-
rate conduit or allow at least 12 inches of space between the power cables
and the data/reader cables.
• Do use shielded cables or metal conduit when necessary to reduce interfering
radio frequency emissions.
DO NOT
