Overview
This chapter introduces Echelon’s MPR-50 Multi-Port Router.
MPR-50 Multi-Port Router User's Guide 1
Introduction
Echelon’s MPR-50 Multi-Port Router performs LonTalk® (ANSI/CEA-709.1
standard) routing between five LonTalk channels: one TP/XF-1250 channel and four
TP/FT-10 channels. The MPR-50 may be used as a 2-way, 3-way, or 4-way
TP/FT-10–to–TP/FT-10 router, or in any combination with the TP/XF-1250 router.
The MPR-50 helps reduce the number of routing devices in multi-channel networks,
reducing both installation cost and time. The MPR-50 provides the highest possible
messaging performance: all four of the TP/FT-10 channels operate at saturation, the
maximum possible operating rate. The MPR-50 includes a flexible power supply, a
ONMARK
L
status, and a time-stamped alarm log that is accessible via the network. In addition,
the router includes an intelligent repeater mode that requires no tools to install and
will typically be used in place of a four-way TP/FT-10 physical-layer repeater.

(EN 50 022) mountable, includes screw terminal connectors for power and channel

MPR-50 Multi-Port Router
Hardware and Software
This chapter provides a description of the MPR-50 Multi-Port
Router hardware, including enclosure construction, mounting
instructions, explanation of indicators and connectors, and
wiring guidelines. In addition, the Multi-Port Router CD
contents and installation instructions are described in this
chapter.
MPR-50 Multi-Port Router User's Guide 3
Mechanical Description
The MPR-50 is 35mm DIN rail compatible, 9 TE wide, and conforms to EN 50 022.
The figure below presents the front view of the MPR-50 Multi-Port Router. The face
of the MPR-50 includes a network diagram that shows how the five routers and the
Monitor are externally and internally connected.

Mounting and Connecting
The MPR-50 Multi-Port Router enclosure is designed for mounting on a DIN rail or
wall/panel. A spring-loaded DIN rail lock securely grabs the DIN rail onto which the
enclosure is mounted. Tabs in the DIN rail area present a pressure fit on the DIN
rail, which prevents the MPR-50 from sliding. The DIN rail lock must be activated to
either remove the MPR-50 from a DIN rail or to slide the router along the DIN rail.
To release the enclosure from the DIN rail, insert a flathead screwdriver into the
DIN rail locking tab and gently pull the tab downwards (away from the enclosure).
Figure 2.2 shows the location of the DIN rail-locking tab.
Wiring Screw Terminals
4 MPR-50 Multi-Port Router Hardware and Software
Four key hole slots in the rear of the enclosure are provided for wall/panel
mounting the router. The key hole slots on each side of the DIN rail allow
mounting normally or upside-down. The top of the MPR-50 includes two scored
alignment guides for positioning the screws and for aligning the MPR-50 with
the screws during mounting.

Figure 2.2 MPR-50 Multi-Port Router Enclosure (back view)
Use the following steps to mount the router.
1. Insert two 6-32 flat-head screws into the surface upon which the MPR-50 is to be
mounted. Mounting dimensions are shown in the following drawing, in millimeters.
3. Be sure the heads of screws are protruding slightly from the mounting surface.
4. Slide the MPR-50 onto the screws. It may be necessary to adjust the screws into or
out of the wall slightly to assure a secure mounting.

MPR-50 Multi-Port Router Dimensions
For mounting purposes, the following figure provides further dimensions of the
router. All measurements below are in millimeters.
Figure 2.3 MPR-50 Multi-Port Router Dimensions
Screw Terminal Connectors
The screw terminals for connecting power and network wires are located on the
bottom edge of the enclosure. The screw terminals accept 0.34–4.0 mm
12AWG) gauge wire. The optimum tightening torque for the screw terminals is
0.75mm (6 lbs. in.) maximum. The ideal flathead screwdriver tip width for use
with the screw terminal connectors is 3mm (0.12”). Wires should be stripped to a
length of 7mm (0.28”). A soldering iron may be used to tin the stripped lengths of
any stranded wires to prevent fraying and inadvertent contact with adjacent
terminals, although this is not required.

Applying Power to the MPR-50 Multi-Port Router
Connect earth ground, if available, to terminal 3. Then connect 9–28VAC (40–70Hz)
or 9–35VDC power to terminals 1 and 2—the power terminals are polarity-
insensitive so the polarity of the DC input is unimportant. The green Power LED
will illuminate to indicate the unit is powered and the Status LEDs will begin
operating within seconds.
Attaching the Router to a LONWORKS Network
Connect the screw terminals marked Router 1 through Router 5 to the desired
channels. Router 1 is for the TP/XF-1250 channel, while Routers 2–5 are for the
TP/FT-10 channels. TP/XF-1250 and TP/FT-10 channel wiring is polarityinsensitive, and the TP/FT-10 connections are link power compatible. Any router
that is not going to be used may be left unconnected.

For complete information about acceptable wire types, maximum stub lengths,
termination requirements, and cable vendors, consult the Junction Box and
Wiring Guidelines for Twisted Pair
available from Echelon’s Web site.

LED Legends
The Power LED will illuminate whenever power is connected to the MPR-50.
The following two tables describe the behavior of the Status LEDs for the Monitor
and for Routers 1–5. For easy reference, shortened versions of the Status LED
legends are printed on the front panel of the MPR-50.
The Status LEDs illuminate as green, orange, and yellow. When yellow is displayed,
orange and green may appear illuminated together depending upon the lighting
conditions.
