CHAPTER ONE – INTRODUCTION
Congratulations for purchasing the finest industrial-grade digital, fast-poll modem available.
The Raymar-Telenetics MIU9.6FPD is a family of low-cost, state-of-the-art, 4-wire private-line
asynchronous digital fast-poll modems designed for point-to-point and multipoint data communications
over solid metallic circuits (such as pilot wires). The MIU9.6FPD provides the consistently high
performance and unsurpassed reliability demanded by today’s industrial and commercial applications. It
also offers a range of data rates from 2400 to 19,200 bps.
The MIU9.6FPD comes in low-voltage and standard-voltage models. In addition, the MIU9.6FPD is
internally surge-protected on both power and analog lines, and operates within the temperature range of
-40°C to +85°C.
The MIU9.6FPD consists of a baseboard and a communication module:
The baseboard includes the power supply regulation and surge protection.
The communication module consists of a Raymar-Telenetics Pony Express™ PE9.6FPD modem
module.
This User’s Guide is designed to let you get your MIU9.6FPD “up and running” as quickly as possible.
It contains all the information you need to configure and install your MIU9.6FPD. It also contains
troubleshooting information in the unlikely event you encounter a problem with your MIU9.6FPD.

INSTALLATION SUMMARY
The MIU9.6FPD installation involves the following steps:
1. Finding a suitable location for the modem. See the section below.
2. Configuring the modem module.
3. Connecting to a transmission line..
4. Connecting to a voltage source.
5. Optional: Connecting a DTE device.
Note: The back panel of the baseboard has four DIP switches. Leave these switches in their
factory-set positions.

Rev. A Page 9 of 25
FINDING A SUITABLE LOCATION
Its rugged enclosure and ability to work within a broad temperature range (-40oC to +85oC) make
your modem ideal for use in locations unsuitable for other modems. The location you select should
provide easy access to the back panel communications interface(s) and front panel power interface.
It should also let you view the red and green LEDs on the front panel.
Note: Raymar-Telenetics offers a rack-mount version of this modem.
Configuring the Modem Module
You configure the modem module using the six DIP switches on the modem front panel and one
jumper. Figure 2-1 shows the location of the switches and jumper.
Switch Settings
The modem has six front panel DIP switches. Table 2-1 describes the switch settings.
Note: For your convenience, the bottom of your modem has a label that summarizes the
configuration DIP switch settings.

Jumper Setting
The modem module has a jumper for selecting the impedance (see Figure 2-1). You can
access the jumper from the front panel of the PE9.6FPD.
Table 2-2 describes the jumper settings. For your convenience, the bottom of your
modem has a label that summarizes the jumper settings.

Note: For point-to-point configurations, both ends
should be terminated with 600 ΩRx impedance. For
multipoint configurations, the host and the distant
modem should be terminated to 600 ΩRx impedance.
CONNECTING to a TRANSMISSION LINE
The MIU9.6FPD has a transmission line interface on the front panel (see Figure 2-1):
The single-channel standalone modem has one transmission line interface.
The repeater has two transmission line interfaces. The left interface is for connection to a
host modem and computer, while the right is for a repeater connection. If you will not be
performing repeater applications, do not use the right interface.
Each transmission line interface is a 4-wire, analog connection, where one pair is used to transmit
data (Tx+ and Tx−) and one pair is used to receive data (Rx+ and Rx−). Tables 2-3 and 2-4 show
the pin numbers and corresponding signals for the single-channel modem and repeater.

For communications to occur, the polarity of the transmit and receive lines from one MIU9.6FPD
to another must connect as shown below:
Tx+ ⇒RX+
Tx−⇒Rx−
Rx+ ⇒Tx+
Rx−⇒Tx−
Important: Polarity of the transmission line must be followed. If connections are
reversed, no data will be received.

CONNECTING to a VOLTAGE SOURCE
The back panel of the MIU9.6FPD provides the power interface (see Figure 2-2). For convenience,
the MIU9.6FPD models can be powered from a wide range of power supplies. For example, the
MIU9.6FPD-LV can be powered from a 12 VDC auxiliary supply on other equipment, while the
MIU9.6FPD can be powered from a standard 120 VAC outlet.
The valid power ranges for the MIU9.6FPD vary by model. Table 2-5 lists the power ranges for
the MIU9.6FPD models. Figure 2-3 shows the connection to the MIU9.6FPD’s power interface.
Note: Before you connect to a voltage source:
Be sure the voltage source is within the permitted range in Table 2-5. Otherwise, your
MIU9.6FPD and any attached devices may be damaged.
Customer-supplied cables must be suitable for the site environmental conditions.
Screw terminals on the power interface accept 28 to 16 AWG. However, surge protection
is guaranteed only if the ground wire is greater than 18 AWG and if there is a solidly
earthed ground connection.
Be sure the power source is not controlled by a wall switch, which can be inadvertently
turned off, shutting off power to the MIU9.6FPD.

This Model… Accepts This Voltage Range…
MIU9.6FPD-LV and
MIU9.6FPD/R-LV 9.0 to 36 VDC
MIU9.6FPD and

Figure 2-3. Voltage Connection to the Modem
CONNECTING an RS-232 DEVICE
The back panel of the MIU9.6FPD provides a female, 9-pin RS-232 connector (see Figure 2-2).
This connector accepts a standard connection to a DTE (RTU), such as an IBM or compatible
personal computer or VT100 terminal, that conforms to the pin assignments shown under “RS-232
(RTU) Interface”.
LEDs
The MIU9.6FPD front panel has two LEDs (see Figure 2-1):
The top LED blinks green when data is being received.
The bottom LED blinks red when data is being sent.
The MIU9.6FPD back panel has one red LED (see Figure 2-2). This LED:
Blinks once per second when power is on, but no data is being received.
Stays on continuously when data is being received.

APPENDIX A – TROUBLESHOOTING
In the unlikely event you encounter a problem using the MIU9.6FPD, refer to the troubleshooting
information in this appendix.
PROBLEM SOLVING
Table A-1 offers troubleshooting solutions for modem problems.
Table A-1. Troubleshooting Suggestions
If… Perform These Procedures…
The modem does not respond to the
attached DTE and all LEDs are off. Check the power supply input for your specific model.
The modem does not receive data and
the green LED on the front panel
does not blink.
The receive line pair may be disconnected from
the modem or polarity may be reversed. Make
sure the transmission line connection to the
modem is accurate and secure.
The modem does not transmit data
and the red LED on the front panel
does not blink.
The attached terminal or DTE may not be
sending data to the modem. Verify that data is
being transmitted.
If data is being transmitted, make sure the RS-
232 cable is sound and securely connected to
the modem and terminal or DTE.
All LEDs on the modem module are
working, but the attached computer
does not work or the modem receives
data errors.
Verify all switch settings on the modem.
Make sure the modem and computer are
configured for the same operating speed.
If necessary, perform the loopback test.
The baseboard jumper and switches
have been changed from their factory
settings.
See “Baseboard Module Configuration
Settings.”
