ADAM-4000 Series User Manual 92
Response !AA(cr) if the command is valid.
?AA(cr) if an invalid parameter was entered or if the INIT*
terminal was not grounded when attempting to change baud
rate or checksum settings.
There is no response if the module detects a syntax error or
communication error or if the specified address does not exist.
! delimiter character indicates a valid command was received.
? delimiter character indicates the command was invalid
AA (range 00-FF) represents the 2-character hexadecimal
address of an analog input module.
(cr) is the terminating character, carriage return (0Dh)
Example command:%2324050600(cr)
response:!24(cr)
The ADAM-4011 module with address 23h is configured to
a new address of 24h, an input range ±2.5 V, baud rate
9600, integration time 50 ms (60 Hz), engineering units
data format and no checksum checking or generation.
The response indicates that the command was received.
Wait 7 seconds to let the new configuration settings take
effect before issuing a new command to the module.
Caution! Only ADAM-4018+ support “% of FSR” and “two’s complement of hexa -
decimal” Data Format.
Caution! An analog input module requires a maximum of 7 seconds to perform
auto calibration and ranging after it is reconfigured.
During this time span, the module cannot be addressed to perform any
other actions.
Caution! All configuration parameters can be changed dynamically, except
checksum and baud rate parameters. They can only be altered when
the INIT* terminal is grounded. (Refer to Baud rate and Checksum con -
figuration in Chapter 2, for the correct procedure)
