S CLASS™ cutter User’s Manual
Detailed Operation 4-17
4.3.2.8 DIN A4 Test
The DIN A4 Test also performs an electrical and mechanical test of the cutter, in order to
check the cut quality, but also provides the user with feedback on knife setting, knife
pressure, knife offset, and cutting depth.
This cut is always run as a DIN A4 portrait/A-size image, regardless of the actual size of the
media loaded. If the media loaded is smaller than DIN A4/A-size, part of the outer box will
be clipped (not cut).
4.3.2.9 RS232 test
The RS232 test routine verifies the cutter’s RS-232-C serial communications (transmit data,
receive data, and hardware handshaking) circuits. This test does not require pen, knife, or
media to be loaded.
To run the RS-232-C test, proceed as follows:
1. Unplug the RS-232-C data cable from the rear panel of the cutter.
2. Use a loop back test cable to connect pin 2 of the cutter’s data connector to pin 3 and
pin 7 to pin 8.
3. Press button. The cutter will start transmitting and receiving data at all available baud
rates and parity settings. The length of the transmissions will vary because of the
different baud rates used. The unit then checks the hardware handshake lines.
Afterwards it will report on the touch screen whether it passed the test or not.
4. Upon completion of the test, remove the loop back test cable from the cutter’s rear
panel RS-232-C connector.
5. Plug the RS-232-C data cable into the connector.
4.3.2.10 Calibrate touch screen
This option makes it possible to calibrate the touch screen. Perform this calibration if the
illustration of the button on the touch screen does not match the area that needs to be
pressed to activate the button.
Press button to start the calibration and follow guidelines on screen.
4.3.2.11 ROM REVISION
Press the button to view information about the cutter’s ROM revision. This information is
often helpful to technicians when diagnosing problems over the telephone.
4.3.2.12 Copy current user
Press the button to copy the user parameters from the current user to all the other users. It
is recommended to do this only when the current user is user 1.
