Chapter 7 I/O, Relay & Counter
Frequency
? is a delimiter character which indicates an invalid command.
AA (range 00-FF) represents the 2-character hexadecimal
address of the module.
(cr) is the terminating character, carriage return (0Dh).
Example command: %0120510600(cr)
response: !20(cr)
The ADAM 4080D module is configured by changing
address 01 to a new address 20, choosing frequency
measurement module, assigning 9600 to baud rate, setting
frequency gate time 0.1 second and no checksum checking
or generation.
The response indicates that the command was received.
Wait seven seconds to let the new configuration settings
take effect before you issue a new command to the module.
