Hi I have an E50 connected to FX1s that's been in service for about five years. Unfortunately, the membrane keypad is gone so I have to replace the E50. I just receieved the new unit, but I can't download the program to it. The E50 is not something that I'm used to, so I'm not sure if I'm using the correct cable or my PC comm port is setup correctly. The info that came with the unit, is pretty lame. The cable I'm trying to use is the same one that I use to program the FX1s, FX2n, etc. Can anyone shed a little light on this? Any help will be greatly appreciated. Thanks heaps in advance! Perry
