• How to Use
Follow the standard operating procedure for the barcode reader that you are using.
Operate the barcode reader while checking the status of the DX. An operation can be
carried out using the barcode reader when it can be carried out on the DX.
Commands
Scan the communication commands encoded in bar codes to operate the DX with
a barcode reader. The communication commands that you can use are listed in
the table below. For information about communication command syntax, see the
Communication Interface User’s Manual, IM 04L41B01-17E.
Command Description
KE Performs key operations
PS Starts or stops memory sampling
EV Starts manual sampling
Causes triggers to occur
Takes snapshots

Command Example
The command to write message number 8 in group 1 is: MS8,GRPUP,1. There must
be a terminator (an enter key code) at the end.
Note
• You can read multiple commands (as many as 10) by putting sub delimiters (semicolons)
between them.
Example: PS0;MS8,GRPUP,1
• When you enter commands using bar codes, you can enter them separated or all at
once. You can separate commands however you want to. For example, you can separate
the command to write message number 8 in group 1, MS8,GRPUP,1, into the following
components: MS > 8 > , > GRPUP > , > 1 > ENTER key code.
• If you use a barcode reader that automatically attaches a footer and a header to every
transmission, the result will be the same if MS is set to the header, the enter key code is set
to the footer, and you scan 8,GRPUP,1.
• When the DX receives an unsupported key code, it clears all of the key codes that it has
accumulated so far.
