I use snuffler master Geo, to use snuffler make the board modification in RS232 interface circuit or Serial OCX. without board modification i fail to load the data into snuffler.
See bellow for details;
1. Cut the track (0V) connecting to IC7
(MAX232) pin 13.
2. Connect IC7 (MAX232) pin 13 to 9-
pin serial socket SK3 pin 3.
3. Connect IC7 (MAX232) pin 12 to IC5
(PIC) pin 18 (RC7).
This action allows the PIC to receive
handshake data from the PC.
To set the PIC program to respond to the
correct serial data transmission routine, initiate
the following procedure:
1. Before switching on power, press and
hold down the Mode switch, S6.
2. The screen will go into serial path
change mode, alternating at about one-second
intervals between a display saying
“SERIAL PORT NORM” (original version)
and “SERIAL PORT OCX “ (Joe’s
OCX).
3. Release switch S6 when the mode you
require is shown. This mode becomes the
active path mode and is also stored into the
PIC’s data EEPROM, to be recalled next
time the program is run.
4. On release of switch S6, normal running
of the PIC program resumes. The serial
path mode may
