Further update. In checking the SSR4, cables etc, i moved the 240v AC cord from Channel '1' to '4' on the SSR4. Plugged everything and ta da - there was output on this channel.
My excitement was short lived however when I tried to turn on channel 4 only - the Bobcat Tester had to be set to all channels for it to light up. To get output from Channel '4', I had to fire up Vixen and have at least 2 channels in the SSR4 group on (e.g. 1&2, 2&3, 2&4, 2&3&4 etc).
I then moved the 240 output cable on the SSR4 to 1,2 & 3 - no output at all (even when set to all channels on).
I again tested the Cat5 cable from the Freestyle to the SSR4 - tester reported cable is ok (and not a cross over).
At least I have some life out of the hardware. I will post the output voltages from the Freestyle to SSR4 soon.
