1 Product Overview
1.1 Introduction
The Model R232 and Model R232-48VDC MultiPort RF Routers are patented
1
devices featuring several unique capabilities both in signal performance and overall
functionality in a test selection environment. This switching system is controllable
over a TCP/IP network using either a web-browser or Telnet interfaces under
automated test instrument operation.
The difference in the two R232 models are their power supplies. The Model R232
uses a standard 90 – 240 volts alternating current (AC) voltage supply, while the
Model R232-48VDC uses a - 48-volt direct current (DC) input. For purposes of this
document the term R232 will be used synonymously unless there is a need to
differentiate the models.
The R232 front panel features a row of LED indicators to indicate the presence of
power and which input is routed to a respective output. During operation a
corresponding LED will light either green or amber indicating which output it is
routed too. If the same input is selected by both outputs the indicator will alternate
between green and amber.
Figure 1: R232 front panel showing LED display of selected inputs.
The rear panel is densely populated with rows of precision “F” style connectors for
the inputs and two outputs. The Ethernet control/management port is also located on
the back.

This document is intended to provide a brief product installation guideline. For more
information on using and controlling the devices please refer to the document
“Monroe X-point Control Protocol MXCP™ R232 MultiPort RF Router
Operation/Interface Manual” which describes the data connection and interface
parameters for each type of interface.
2 Power Connections
As mentioned above the R232 and R232-48VDC differ by their respective power
supplies and therefore have different connection types reflective of the input style.
Although the inputs differ the connection points and cable arrangements are the
same.
Both models feature the patented Pocket Power Supply™ which is a unique opening
on the right side of the chassis (facing the front) for power input. This is shown in
Figure 3 below.
Figure 3: Position of Pocket Power Supply opening.
Along the same side of the chassis is the power cable management tray, this allows
the power cable to be cleanly supported along the edge and toward the rear of the
chassis.
2.1.1 R232 Power Connections - AC
The in the pocket power supply of the model R232 is an International
Electrotechnical Commission (IEC) standard receptacle as shown in Figure 4 below.

The R232 ships with a right-angle IEC power cable similar to
the one shown on the right.
The plug is inserted in the AC receptacle on in the Pocket
Power Supply opening and the wire is routed along the cable
management tray as shown in Figure 5.

2.1.2 R232-48VDC Power Connections - DC
The model R232-48VDC uses a different connector in the Pocket Power Supply
opening. This connector is a two-pin removeable terminal block where one side
remains mounted to the chassis as shown in Figure 6, while the mating connector
can be easily removed to facilitate installation of the power cabling.
IMPORTANT NOTE:
CLOSELY OBSERVE THE CONNECTION POLARITY TO AVOID DAMAGE!

(shown with mating connector removed)
Along the same side of the chassis is the power cable management tray which
allows the power cable to be cleanly supported toward the rear of the chassis.
The R232-48VDC is not supplied with any power wiring. This is the sole
responsibility of the customer. The terminal strip can accept wires up to 16 gauge.

Once the wires are attached to the removable terminal strip it can be connected to
the mating connector in the Pocket Power Supply opening. There are two retention
screws on the terminal strip to secure the connector to the device.
The wires can then be routed along the power cable management tray and toward
the rear of the chassis. The completed connection and wire routing can be seen in
Figure 7 below.

Once power connections are made the unit is ready for mounting.
3 Mounting
The R232 is designed to be mounted in a standard Electronic Industries Alliance
(EIA) 19” rack frame using the four mounting screw holes on the front of the chassis.
The 1.75” high chassis is a uniform one rack unit (RU) height.

The 1.75” (4.45cm) high chassis fills a uniform one rack unit (RU) in height.

The 1.75” (4.45cm) high chassis fills a uniform one rack unit (RU) in height.
IMPORTANT NOTE:
There can be a tremendous amount of weight applied to the face plate when the unit
is fully cabled. Users are encouraged to provide a means of cable management at
the rear of the rack to avoid excessive cable weight force on the unit.
Because the device consumes very little power (<25 Watts) there are no venting
restrictions. This allows stacking devices without the need or provision for spacing in
between units.
4 Test Cable Wiring
Much like the internal circuitry, the R232’s input and output connectors are a
precision component and must be treated as such. Therefore, it is critical that NO
EXCESSIVE FORCE BE APPLIED TO THE INPUT/OUTPUT CONNECTORS.
CRITICAL NOTE:
Do not exceed 10 in/lbs. (1.12 N/m) of torque on any F-connector!
OVER TORQUING THE CONNECTORS MAY CAUSE IRREPARABLE INTERNAL
DAMAGE AND IS NOT COVERED UNDER WARRANTY!
Please be aware that generally available cable F-connector torque wrenches are
typically set for 20 in/lbs. used for outdoor connectors. Moreover, they are
notoriously unreliable in delivering proper torque for these precision components and
therefore it is strongly advised not to use them in this application.
4.1 F-Connection Rule of Thumb:
Finger tighten the cable to the F-connector, then tighten no more than a quarter (1/4)
turn if at all. This should provide a secure connection without applying a damaging
amount of torque to the connector.
