[WriteLog] Need help with Multi-Keyer Push-To-Talk

[bill.echols@ieee.org (Dr. Bill Echols)]

I have not succeeded in getting WriteLog and the W5XD Multi-Keyer to enable
PTT on either of my two radios. No voltage or resistance changes ever occur
on the PTT_L, PTT_R, LPT_R pin 16, or LPT_L pin 16 when I depress my
footswitch (which changes from a 4.9 volt to zero volts showing the
footswitch is good). I can pull down the voltage with a jumper to ground on
PTT_L or PTT_R and the respective radios will key; CW works fine.

The schematic does not show opto-isolators on the PTT_L or PTT_R leads but
the description states they exist. Does anyone have a complete schematic? Is
there some kind of software configuration I need in the .ini file?

Bill, NI5F
