Set Communications Mode
The communication diagnostics mode is a troubleshooting tool for
checking the interconnection between the print engine and the host
computer. When
DIAGNOSTICS is selected, all data sent from the host
computer to the print engine prints as straight ASCII characters, with the
hex value below the ASCII text. The print engine prints all characters
received, including control codes, like CR (carriage return). A sample
printout is shown in Communications Diagnostics Test on page 117.
Notes on diagnostic printouts are defined as follows:
• FE indicates a framing error.
• OE indicates an overrun error.
• PE indicates a parity error.
• NE indicates noise.
Default: NORMAL MODE
Selections: NORMAL MODE, DIAGNOSTICS
To change the value shown:
1. Press the left or right oval to toggle between the options.
2. For any errors, check that your communication parameters are correct.
3. Set the print width equal to or less than the label width used for the test.
See Set Print Width on page 58 for more information.
Set Control Prefix Character
The print engine looks for this two-digit hex character to indicate the start
of a ZPL/ZPL II control instruction. The “H” that is displayed indicates
Hexadecimal and is not part of the value.
Note • Do not use the same hex value for the control, format, and
delimiter character. The print engine must see different characters
to work properly.
Default: 7E (tilde—displayed as a black square)
Range: 00 to FF
To change the value shown:
1. Press the left oval to move to the next digit position.
2. Press the right oval to increase the value of the digit.
