$AA8Ci[CHKSUM](CR)
$
Delimiter character
AA The address of the module to be read in hexadecimal format (00 to
FF)
8 The command to read the Type Code information for the Analog Input
channel
Ci i specifies which Analog Input channel to access for the Type Code
information, zero based (0-5)
Response:
Valid Command: !AACiRrr[CHKSUM](CR)
Invalid Command: ?AA[CHKSUM](CR)
! Delimiter character to indicate a valid command
? Delimiter character to indicate an invalid command
AA The address of the responding module in hexadecimal format (00 to

Examples:
Command: $017C0R08 Response: !01
Sets the Type Code for Analog Input channel 0 of module 01 to 08 (-10 to
+10 V) and the module returns a response indicating that the command
was successful.
Command: $018C0 Response: !01C0R08
Reads the Type Code information for Analog Input channel 0 of module
01 and returns a response indicating that the command was successful,
with a value of 08 denoting that the input range is -10 to +10 V.
Command: $018CF Response: ?01
Attempts to read the Type Code information for Analog Input channel 15
of module 01, but returns a response indicating that the command was
