The e-Twinax Controller Model 4691

Twinax-to-IP Print Server

Supports Connection of
1 Twinax Printer Over IP to a New Power8,
Power7 or Any iSeries AS/400


The e-Twinax Controller is a "Twinax-to-IP" controller that can be used to connect Twinax devices to an IBM 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 at right.  Click on each photo of the eTwinax Controller for large images.

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 Printers (SCS and IPDS).

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 legacy Twinax Controllers do.
