4-156 ADAM 4000 Series User's Manual
Command Set
4050, 4052, 4053, 4060, 4051, 4055, 4068
Since the ADAM-4060 has only four output channels all the
meaning full values lie between 00h and 0Fh. The value 0Ah
would mean the following for the ADAM-4060:
01111010
digital value:
76543210
00001010
digital value:
- - - - 3210
4050, 4060, 4055, 4068
#AABB
Name Digital Data Out
Description The command
either sets a single digital output channel or sets
all digital output channels simultaneously.
Syntax #AABB(data)(cr)
# is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of the digital I/O module you want to set its output
value.
BB is used to indicate whether all channels will be set or a
single channel will be set. In the last case BB also indicates
which channel. Writing to all channels (write a byte): both
characters should be equal to zero (BB=00). Writing to a single
channel (write a bit): First character is 1, second character
indicates channel number which can range from 0 to 7.
(data) is the hexadecimal representation of the digital output
value(s).
When writing to a single channel (bit) the first character is
always
0. The value of the
second character is either 0 or 1.
When writing to all channels (byte), both characters are
significant (range 00h-FFh). The digital equivalent of these two
hexadecimal characters represent the channels values.
The amount of channels on the ADAM-4050, ADAM-4055,
ADAM-4060 and ADAM-4068 differs. The value 7A would
mean the following for the
8 channels on the ADAM-4050,
ADAM-4055 and ADAM-4068:
ADAM-4050/4055/4068
channel no.
ADAM-4060 channel no.
