Chapter 4 Command Set
4-7
(Continue %AANNTTCCFF)
Response !AA(cr) if the command is valid.
?AA(cr) if an invalid parameter was entered or 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 or
communication error, or even if the specified address does
not exist.
! is a delimiter character indicating that a valid command
was received.
? is a delimiter character indicating that 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 is configured to have address
23h 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 for 7 seconds to let the new configuration settings take
effect before issuing a new command to the module.
NOTICE: 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.
NOTICE:
All configuration parameters can be changed dynamically,
except checksum and baud rate parameters. They can only be altered
when the INIT* terminal is grounded. (Please refer to Baud rate and
Checksum configuration in Chapter 2,
for the correct procedure)
