Epson HX-20 Troubleshooting Tips

HX-20 TROUBLESHOOTING TIPS
SYMPTOM
System displays garbage on the main
menu, or a "trap"
error is displayed.
8148 printer RS-232 interface card,
installed in an Epson printer prints
"*"
characters (framing errors).
I
Skiwriter word processing ROM
can not be used with the external
display controller.
POSSIBLE SOLUTION/REASON
Initialize the unit by pressing
CTRL key and the "@" key, from
the main menu. A DATE/TIME
prompt should appear. The date
and time has to be entered as
shown (no "/" or ":" characters)
The HX-20 RS-232 port signal
rise time is slow. The 8148
tries to receive data too soon.
Recommend using another I/F
card, such as the 8145.
Skiwriter was not designed to
operate with the display
controller.
