Using the OMP-MODL 2-6
3-Button System Initialization:
A complete initialization of the logger that will clear data memory
and program memory can be performed using the ENABLE, STOP
and RESET buttons. This sequence is normally only used when a
unit is upgraded in the field with a new EPROM or in the event that
the Program memory has become corrupted due to unforeseen
events such as disassembly while powered up, improper insertion of
a PCMCIA card, exposure to an extreme noise noise glitch (for
example, from a nearby lightning strike) that has caused the
microprocessor to lose its place or lock-up or other malfunction.
To perform this 3-Button Initialization,
1. Depress and hold the ENABLE button
2. Momentarily, depress the STOP and RESET buttons
simultaneously.
3. After a second or so, release the ENABLE button.
4. Observe the Feedback LED. After a few seconds, the
Feedback LED should blink 10 times in succession. This
indicates that a complete system initialization has been
performed.
If the logger is equipped with a ML-DISP modules, after a
short sequence of display messages on the LCD, a
SYSTEM INITIALIZED message should display
momentarily indicating that the logger was properly
initialized. If this message does not display, repeat the
procedure.
After initialization, reprogram the logger with a new Net Program
and the unit is ready to operate.
RS-232 Serial Communications Port
A female 6/6 RJ-12 modular phone type jack is provided on the MLCPU-1
for RS-232 communications. A mating 6 conductor cable (CAR-4) plugs into
this port. The other end of the cable plugs into the 9-pin or 25 pin serial port
on a PC via a modular plug to DB-9F (P/N: RJDB-9H) or DB-25F (P/N:
RJDB-25H) adapter. Note that this port is not for direct connection of a
telephone line.
