Omega Vehicle Security Comprehensive Guide to MODL 3 System Initialization and Communication

2... OMP-MODL System Base

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.
