Synscan RJ11 port voltages (Synscan to PC)
Few days ago I got a 2nd hand NEQ6 and want to upgrade the firmware on the synscan v3 as it is running some very ancient version.
I have found pinouts for the RJ11 connector but could nowhere find what voltages are used. I made a cable to 5V USB-serial FTDI converter (TTL levels) but that did not work.
Is it using standard RS232 voltages (-13V to 13V or similar)? Don't want to fry anything.
Thanks in advance,
Luka
