RE: Twinax Device Addresses

This is going back many years, but I recall that some of those star hubs
required the dip switches to match the configuration on the hub (meaning
you had to set the device plugged into the star hub port 1 to address 1
for it to work), and others didn't have any real affinity to the switches.
So if you had two devices set to address 1 on the same port (meaning
controller port) they would conflict. You may have to go muck with the
dip switches to get things working properly.

When I GO HARDWARE and run " 2. Work with local workstation resources," I
see two controllers: CTL03 and CTL05. But there's only one "loon" (brick)
coming out of the back of the 520. There are five [5] of these old twinax
dot matrix printers; they are all used (to varying degrees) and all of
them show up when I run WRKCFGSTS *DEV.

When I run PRTDEVADR against CTL03, I get a message that " Controller
CTL03 not found" (CPF2602). My set-up is identical to that described by
Loyd.

I know that there are two printers configured for Port 1 because I looked
at their configuration. This whole question started, in fact, because I
had to swap these printers out yesterday, and I was looking for an unused
address on the port that I could use temporarily for one of them so I
could change the configuration without having to muck around with those
DIP switches.

Thanks.

Do you have multiple Twinax controllers?

We still have a few twinax line printers here. They are connected to the
System i via an Ethernet patch panel; the twinax control is connected to
the
panel with a balun and Ethernet cable.

Pretty rudimentary stuff, I think. My question is: Why, when I run the
PRTDEVADR command these printers do not show up? In fact, the only thing
that shows up in the list is the old system console at port 0 address 0.
