I have several tt1 and tt5's and have been trying to fire my camera's I have 2 Mark IV's and a 5D II and just got a new cable the CM-N3-ACC had one already but I thought is was bad because I couldn't get the cameras to work so bought a new one and still nothing. All firmware is up to date. I put the tt5 on camera and hook up the cable and try to fire it with the tt1 and nothing. Tried different channels with no success. I used to do this all the time with the Plus II. I sure would appreciate any help.
One thing I noticed when I reviewed the new user manual for the tt1&tt5 units. It gave a step by step setup foe each of the configurations that are endorsed by PW. I could go Copt and paste it here for you but you will learn more by going and downloading it a reading it for yourself as you will find the info you plus other valuable knowledge that you'll need later on.
