Re: Move a line printer

Could be a factor. I forget if the 2746 was the newer twinax controller.
IBM did say the newest (which is REALLY relative) twinax controller did
not have the signal power of their earlier models. It was in a Memo To
Users or some such thing.

That standard RJ45 connector, if it is connected to the printer via a
balun should be connected to a balun on your 2746 (or some dongle hanging
off of it). There may be items in between these two, like repeaters to
help the signal strength. Back when we were using this mess we had to use
repeaters. But, we were stringing it through various cables throughout
our complex. We also ran into various other issues. Like at certain
times of the day when fans were turned on it would drop the signal on the
cables (which were strung in close proximity to the fans).

Not sure where you'd find the specs on how far you'd get signal. I
remember real twinax had limits like:
- a cable had to be a minimum of 1 meter.
- There could be a maximum of 6 devices on the line.
- There could be a maximum of 11 devices and splices on the line. (Which
we tried to push the splices a few times.)
And I forget the length.

You may want to find an alternative. The Power 7 does not support any
twinax controllers. That printer has really got to be showing some age.
Do you really need a line printer anymore? We do not use any. If you
need one this may be the time to get an ethernet printer.
