message Serial printer
cable or
Model 24SII
DES losing
power during
transmission
to printer The HP LaserJet will give this message
when its DSR line (Pin 6) goes from
positive to negative or zero volts. Verify
that Pin 6 on the printer side of the serial
cable is either connected or jumpered as
shown in Appendix A.3. Also verify
M24SII's AC power source.

menus Cable Use correct serial cable between PC and
Model 24SII DES. Check handshaking
lines in TERM program.
Port
configuration Match baud rate, word size, stop bits,
parity and handshaking lines between
Model 24SII DES and PC. This can be
done using TERM program.
Port selection Ensure PC COM port is connected to
configuration port of Model 24SII DES.
Software Use dumb terminal or a PC running a
terminal emulation program (TERM
supplied by BayTech, or another
program such as CrossTalk).

and printer is completed. There should
be no red LEDs illuminated when trying
to enter the configuration mode.

cable type (no

control) Check manual for correct pin-outs
between PC and Model 24SII DES, and
between Model 24SII DES and printer.
Check handshaking. A way to check is
to force an error condition at the printer
(i.e. remove paper tray from laser printer
or turn off-line with power still applied).
Send print job to printer. If printer LED
goes off, you can conclude no
handshaking was done. On serial ports,
check Model 24SII DES configuration to
match handshaking (i.e. you must be
using CTS/DTR or XON/XOFF for both
Model 24SII DES and printer). Also
