Command Set
In this example the ‘30’ and ‘31’ are the hex ASCII codes for the characters ‘0’ and ‘1’ respectively. The Extended Address is ‘01’.
Read Identification (RID)
The Read IDentification command reads back the user data stored by the IDentification (ID) command. The ID and RID commands are provided as a convenience to the user to store up to 16 characters of information in the A2400 EEPROM. The stored information could be anything from the date of installation to a device tag indicating where the device is positioned in a system.
Command: | $1RID |
Response: | * TANK FARM 1 |
Command: | #1RID |
Response: | *1RID TANK FARM 11F |
Read Long Prompt(RLP)
The Read Long Prompt command reads back the extended addressing long form command prompt stored in the module’s nonvolatile memory with the Long Prompt (LP) command. The response to the RLP command is a two character hex value of the ASCII long form prompt character.
Command: | $1RLP |
|
Response: | *7D | (7D = } = Factory Setup) |
Command: | #1RLP |
|
Response: | *1RLP7DC4 |

Remote Reset (RR)
The Remote Reset (RR) command allows the host computer to perform a program reset on the module’s microprocessor. This may be necessary if the module’s internal program is disrupted by static or other electrical disturbances. Once a reset command is received, the A2400 will read the setup information and delay values from EEPROM and activate the read values.
Command: $1RR
Response: *
