Blonder Tongue agile modulator settings

[bandersen]

I just picked up a Blonder Tongue AM60-550B without a manual

Can someone help me out with the front panel settings and rear connecors ?

I think the output channel is set using a little binary math. Channel 5 would be 0000 0101 - right?

How about those switches to the left? Should I use STD or BROADCAST if I'd like to transmit to my vintage TVs?

Finally, do I need to do anything with the jacks and screw terminals in the middle of the back? I have a different, older model that has a short coax connecting the IF IN to IF OUT. Do I need that ?

Thanks!
