FiberPlex TD-1580 - Manual (Page 5)

Introduction
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.
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).
Key Features
 Compatible with:
o TIA/EIA‐530 (RS‐530)
o MIL‐STD‐188‐114A balanced type 1 and type 2
o FED STD 1030A
 Can alternately be used for
6x4 RS‐422 and 1x2 RS‐232
 EIA‐530 and RS‐422 channels support data rates from DC to 6.144 Mbps
 Can be used for up to 6 universes of DMX lighting control
 Includes power adapter as well as a 3‐position Phoenix™
Theory of Operation
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]. The table later in the manual shows how
these channels are pinned out.
Differences between TD‐1580 and TD‐1581
The TD‐1580 has a female (sockets) DB‐25 connector and mates with the DTE.
The TD‐1581 has a male (pins) DB‐25 connector, mates with the DCE and has clock regeneration functions.
Getting Started
Initial Inspection
Immediately upon receipt, inspect the shipping container for damage. The container should be retained until
the shipment has been checked for completeness and the equipment has been checked mechanically and
electrically. If the shipment is incomplete, if there is mechanical damage, or if the unit fails to operate notify
FiberPlex and make the shipping materials available for the carrier's inspection.
