• When normal

• When abnormal

The following tables list the command parameters used in explicit messaging to read/

write the settings and status of sensor amplifiers and to issue motion commands.

For details about how the master unit performs explicit messaging using command

parameters, see:

"Issuing a Motion Command to a Sensor Amplifier" (page 3-22)

"Reading/Writing Settings or Status of a Sensor Amplifier" (page 3-23)
