The e-Twinax Controller is a
"Twinax-to-IP" controller that can be used to
connect Twinax devices to an IBM Power9, Power8, Power7
or any iSeries or AS/400 over any IP connection,
locally or remotely.
The simplest way to look at the e-Twinax Controller is as an "External
Twinax Workstation Controller". You can even use your
current IBM 8-port Twinax "Brick" on it as
shown above. Click on each photo of the eTwinax Controller for
Some models also support an 8-port RJ45
"Brick". Each RJ45 port is just like a Twinax Host
Port with an RJ45 Balun on it.
When used remotely, it is a replacement for SDLC
Remote Controllers such as the IBM 5494 and 5394, the Perle 594e,
494e and 394, and other IBM compatible Twinax controllers from I-O
Corp., Decision Data and Idea.
It will support Twinax Display Stations and Twinax
Being it uses TN5250e as it's communication
protocol, it does not require any SNA protocols. In addition, it
does not require DLSw (Data Link Switching) as IBM 5494s and other
Twinax Controllers do.

Model 4628eTwinax Controller -
28 Twinax Address/Device Support
eTwinax Information Request -
view of e-TwinST@r Controller
with RJ45 unit attached
The e-Twinax Controller
now has an optional model that includes a built-in unit featuring 8 (or 16) RJ45
sockets. Twinax devices working over CAT5 lines are connected directly
to the Controller, saving the cost of an active star hub and
eliminating the need for power sources and additional space in the
communications closet, as well as the extra set-up and maintenance
time. The RJ45 Ports of this option operate just as a Twinax
port with an RJ45 Balun attached to it.
If you need to connect more Twinax Devices than the number of physical
ports on an e-Twinax Controller, please read the explanation in the next
section. The e-Twinax Controller model must be able to support the
number of devices you need to connect.
(4800 Series) is available in models with support for 8, 16, 28,
56 or 112 Twinax addresses/devices. The 4800 Series is fully
upgradeable from one model to the next allowing for growth from 8
to a full 112 device support. The 4800 Series
also supports connection of the 8-Port Twinax Brick as the
e-Twinax 4600 Series as well as the IBM 8-Port Twinax Brick
from your existing Internal Twinax Workstation Controllers.
Upgrades are made by
simple entering a new software key in the configuration section of the
e-Twinax. You can upgrade remote locations by accessing the upgrade
portion of the configuration over your WAN. Upgrading is done
while the controller is in full operation. There is no need to
have those users connected to it brought down. This eliminates
the need other controllers have to bring them down while increasing
their device capacity or adding options.
Explanation of Device Support
for the Twinax and RJ45 Ports of e-Twinax Controller
As with the standard AS/400 8-port "Twinax Brick" from the
Twinax Workstation Controller, each Host Port (Twinax or RJ45) of the
e-Twinax will support up to a maximum number of 7 device addresses
(0, 1, 2, 3, 4, 5, 6), up to the maximum number of devices the particular
model controller will support. This convention holds true to all
Twinax or RJ45 Host Ports of S/36, S/38, AS/400, iSeries and all IBM,
Decision Data, I-O, Idea, and Perle Remote Controllers except for the very
old 5251-12 and 5294 controllers that only supported a maximum of 4
addresses per Host Port.
For example, an IBM 5394-01B Controller has three Twinax Host
Ports. Three ports with 7 devices each would total 21. The
5394-01B only supports 16. You can distribute those 16 device
addresses across those three ports however you see fit. That could
be 7 on the first port, 7 on the second port and 2 on the third
port. You could also have 6, 6 and 4 or any other combination that
totals 16 device addresses with a maximum of 7 on any one port.
Another example is the 4616 (Twinax Host Ports) and 4816 (RJ45 Host
Ports) of the e-Twinax Controllers. Both of these models will
support 16 Twinax addresses/devices but only have 8 physical
ports. Using the same logic as with the 5394-01B example, you
can connect devices to ANY of these 8 ports as long as the total number of
addresses used is 16 or less. For example you could use the same 7,
7, and 2 on the first three Host Ports as with the 5394. Being these
models have 8 Host Ports, you could also put 2 devices on each port for a
total of 16. You could also have 4, 4, 4 and 4 on four of the 8 Host
Ports or any other combination that totals 16 device addresses with a
maximum of 7 on any one of the 8 ports.
If you need to connect more physical devices than the number of ports
you have two options.
First, you can "cable-through"
your Twinax devices from one to the next using actual
cables. Using this method you can connect up to 7 devices to a
single Host Port. If you are using multiple session terminals, the
number of physical devices would be less as each Host Port will only
support 7 addresses.
can add a
Active Star Hub such as the
Express Active Star Hub to your setup. These Active Star Hubs connect
to one of the controllers Host Ports either by Twinax Cable or Category 5
(CAT5) cable, and expand the single port to 7 RJ45 ports corresponding
with the device addresses available on that port of 0, 1, 2, 3, 4, 5, and
6. This is the same whether the e-Twinax Controller has Twinax Host
Ports or RJ45 Host Ports. In this implementation each Twinax Device
would be required to have a Twinax-to-RJ45 Balun on it to allow connection
with a CAT5 cable.
Host Ports of the e-Twinax Controller are operationally the same as a
Twinax Host Port with an RJ45 Balun attached to it.uest - New 040416
