@#
DATA FROM SCALE CHANNEL #
Use the @# (where # = 0-31) commands in conjunction with the @Vx or @Wx commands to cause the print
string to take data from any scale channel listed in the Channel List. See the CellScale manual for information
on setting up a channel list. When preceded by the @0-31 command, do not use the @ sign in front of the
weight command; e.g. @1W3. If the @W or @V commands are used without the @0-31 in front, the scale
mode currently displayed will provide the data.
Once an @# command is sent, all subsequent scale related commands will function on the set channel,
until it is changed again with @#.
Input Data Form (examples, any W or V command will work):
@1W1
Print the Weight in the last display mode of the scale channel in position 1 of the scan list.
@2V0
Print the Gross Weight of the scale channel first in the scan list.
@31W2 Print the Net Weight of the scale channel last in the scan list.
Output Data Form:
Is dictated by the suffix command, see “@W” and “@V”.
Output Data Form:
Is dictated by the suffix command, see “@W” and “@V”.
@?
QUERY SCALE CHANNEL #
Use the @? to print the active scale channel # set by the @# command.
COMPUTER OPERATION VIA HOST CODES
The MSI-3750CS can interface to computers via RS-232. All functions can be controlled remotely and
all setups can be downloaded automatically. The computer can query the scale at any time to get status,
weight, or accumulated totals.
General Protocol
The MSI-3750CS responds to ASCII commands that consist of a two letter mnemonic. Depending on the
command, a 1 or 2 digit item selection (sub-code) may be required. Certain commands require user supplied
data. Commands sent from a host computer can be chained together in any order. Commands are terminated by
another command or by a semicolon (;). It is necessary to end a multiple command string with the semicolon
as a terminator. Variable length numeric data must be terminated by a semicolon or by another command.
Variable length alphanumeric data must be terminated by a semicolon before adding additional commands.
Commands are case sensitive, only capital letters are used. The 3750CS will not accept commands if it is in any
setup mode caused by pushing the SETUP key.
It is important that the final character sent to the 3750CS is a semicolon (;).
“@” Commands Under Computer Control
The “@” commands also function under computer control, however they act differently than standard computer
commands. The “@” commands, when received by the 3750CS, will cause the immediate transmission of the
asked for data type out the Comm port. The “;” delimiter is usually not necessary unless the “@” commands are
combined with the standard computer commands. The preferred way to get data from the 3750CS is to use the
“CD” command, set up a print string with all the @ codes desired, then use the “PR” command to cause a data
transmission. Once the print string is set up with the desired data, only the PR command is needed.
