known state. This state is called the INIT* state.

INIT* state defaults:

Baud rate:9600

Address:00h

Checksum:disabled

Forcing the system into the INIT* state does not change any parame-

ters in the system's EEPROM. When the system is in the INIT* state

with its INIT* and GND terminal shorted, all configuration settings can

be changed and the system will respond to all other commands

normally.

Changing Baud Rate and Checksum

Baud rate and checksum setting have several things in common:

•

They should be the same for all systems and host computer.

•

Their setting can only be changed by putting a system in the INIT*

state.

•

A changed setting can only take effect after a system is rebooted.

To alter baud rate or checksum settings you must perform the follow-

ing steps:

1. Power on all components except the ADAM-5000 system

2. Power the ADAM-5000 system ON while shorting the INIT*

and GND terminals as shown in Figure A-3.
