Receive test
AP4.4 AP5.4 AP7.t
Serial connection
Assumption is a serial data line between PC and printer; the parameter
INTERF.PARAM. > Interface must be set on RS232 or RS485.
1. Start the MS-DOS-window (using Windows).
2. Set the interface to the values adjusted at the printer by means of MS-DOS
command MODE:
Example of printer settings:
– Baud rate: 19200
– No. of data bits: 8
– Parity: none
– Stop Bits: 1
– Data synch.: RTS/CTS
DOS-Command: mode com2 19200 8 n 1
(if com2 is the serial port)
3. Press the Online-key to start Receive test.
4. Send any file to the printer (Condition: com2 = Printer port; anyfile.txt = any
file ):
copy anyfile.txt com2 (add /b for binary files)
The following shows up on the printer display:
xxxxxx is the size of the sent file in bytes. This value is being counted up dur-
ing the test. The test is complete if the file size does not vary any more. If the
bytes announced at the printer match the size visible in the MS-DOS window,
transfer was successful. Otherwise, transmission errors occurred.
Parallel connection
Assumption is a parallel data line between PC and printer; the parameter
INTERF.PARAM. > Interface must be set up on Centronics. Proceed as follows:
1. Run Receive test. To this call the parameter
