4-92 ADAM 4000 Series User's Manual
Command Set
4018M
@AAD
Name Read Memory Configuration
Description The command requests the configuration data from the analog
input data logger at address AA.
Syntax @AAD (cr)
@ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of an analog input data logger.
D identifies the Read Memory Configuration command.
(cr) is the terminating character, carriage return (0Dh)
Response !AACCSDTTTT(cr) if the command is valid.
! is a delimiter character indicating a valid command was
received.
AA (range 00-FF) represents the 2-character hexadecimal
address of an analog input data logger.
CC (range 00-FF) represents the data storage status of each
channel. The ADAM-4018M has 8 channels, bit 0 representing
channel 0, and bit 7 representing channel 7. A mask bit value
of ‘1’ enables data storage in the specified channel, while a
mask bit value of ‘0’ disables data storage.
S represents the standalone mode. In order for the ADAM-
4018M to operate in the field, you must power on the memory
module by setting this value to ‘1.’ Otherwise, the data will not
be recorded.
D represents the data logging mode. ‘0’ enables Standard
Mode, where all eight channels record the normal data accord-
ing to the sampling interval. ‘1’ enables Event Mode, where all
eight channels record the data if its value is over the High
Alarm limit or under the Low Alarm limit. ‘2’ enables Mixed
Mode, where channels 0 - 3 act as the standard logger and the
channels 4 - 7 act as the event logger.
TTTT (range 2-65535) represents the sampling interval in
seconds.
(cr) is the terminating character, carriage return (0Dh)
