Overview

The TD-1580 and TD-1581 pair together to form a powerful balanced serial data transport solution. The DB-25 connectors are pinned out to directly support an EIA-530 serial link. However due to the transparency and flexibility of the design, the TD-1580/81 can be used as 6x4 independent 6 Mbps RS-422 channels and 2x1 independent 256 Kbps RS-232 channels (see below for details). This incredible versatility can solve a myriad of serial data communications problems. Your once limited serial links can not only be consolidated but extended to over 20 Km on a single fiber pair. SCADA (supervisory control and data acquisition), Telecommunications, Facility Automation and Control, even DMX Lighting control applications can all benefit from the TD-1580/81. For more advanced systems, a ‘Regeneration’ switch on the TD-1581 allows users to toggle between synchronous applications that require Send Timing (ST) and asynchronous or synchronous applications that require Terminal Timing (TT).

How do we get so many channels?

By using a technology unique to FiberPlex products called ‘transparency’, we are able to use all the clock, data and control channels of the standard EIA-530 interface completely independently of one another. This provides the ability to have (4) bi-directional RS-422 serial with (2) unidirectional RS-422 and (1) bi-directional RS-232 with (1) uni-directional RS-232, or even independently as (6) RS-422 in one direction and (4) in the other [6x4] and (2) RS-232 in one direction and (1) in the other [2x1].
