1. STANDARDS
All Telenetics dial-up modems are designed to meet the following Standards:
USA: FCC Part 15, Class A and Part 68
Canada: DOC Standards CS-01, CS-02 and CS-03
CANADIAN DEPARTMENT OF COMMUNICATION NOTICE
NOTICE: The Canadian Department of Communications (DOC) label identifies certified
equipment. This certification means that the equipment meets certain telecommunications network
protective, operational and safety requirements. The department does not guarantee the equipment
will operate to the user’s satisfaction.
Before installing this equipment, make sure you are permitted to connect it to the facilities of the
local telecommunications company. You must install the equipment using an acceptable method of
connection. In some cases you may also extend the company’s inside wiring for single line
individual service by means of certified connector assembly (telephone extension cord). You should
be aware, however, that compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility
designed by the supplier. Any repairs or alterations made by a user to this equipment, or equipment
malfunctions, may give the telephone communications company cause to request the user to
disconnect the equipment.
For your own protection, make sure that the electrical ground connections of the power utility,
telephone lines and internal metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.
Caution: Do not attempt to make electrical ground connections yourself, contact the appropriate
electric inspection authority or an electrician.
NOTICE: The load number (LN) assigned to each terminal device denotes the percentage of the
total load to the telephone loop used by the device, to prevent overloading. The termination on a
loop may consist of any combination of devices, subject to the requirement that the total of the load
numbers of all the devices does not exceed 100.

2. PRODUCT OVERVIEW
The MIU2.4, MIU9.6, MIU14.4 & MIU28.8 are industrial grade dial
modems for connection to the Public Switched Telephone Network..
They can be powered from a wide range of AC and DC power supplies,
they are internally surge protected on both the power and analog lines,
and they will operate in temperatures from -40 to +85 deg C.
Internally, each unit consists of a baseboard and a communication
module. The baseboard includes the power supply regulation and surge
protection. The communication module is a Telenetics™ Pony
Express™ Dial Modem Module.
The MIU is packaged specifically for the harsh environments found in
utility substations and industrial facilities. Though functionally similar to
commercial modems, the MIU includes special features that make it
particularly well suited for utility and industrial applications:
Environment: The MIU has been designed specifically for use in
harsh environments. In addition to an extended
temperature range (-40 to +85º C), the MIU includes
surge, shock, vibration, and safety features superior
to those of conventional commercial modems.
Power Supply: The MIU can be powered from a broad range of AC
and DC power supplies, such as an auxiliary supply
(eg; 12VDC) from another piece of equipment,
125VDC from a station battery or a standard
120VAC.
Low Power: The MIU dial modem can be configured to enter into
a “power down” mode. In this mode, an MIU will
consume only a small fraction of its active power
while waiting for either controller or telephone
activity.

MIU Installation, Operation & Diagnostics Edition: March 30, 1998 Page 4
Industrial: The MIU is packaged in a rugged, compact, non-
metallic (ABS) enclosure. Designed for unmanned
locations, the MIUs do not include the array of
pushbuttons and LEDs normally associated with
consumer-type modems. Configuration is by dip
switches and/or software (“AT”) commands.
Standard industrial connectors for data, analog and
power interfaces allow reliable interconnection to
other industrial components.

4. POWER MODES
Mode Description Power
Consumption
Power On Factory Setting: Full power is always
available to the modem.
See Section 3
Sleep If the modem is on hook for a
predetermined period (PE2400 = 5
seconds; PE2496, PE14.4 & PE28.8 =
software configured: Set S24 to desired
delay in seconds), it will drop to a low
current mode).
The modem will instantly “wake up” to
full power by either an incoming ring
signal or any transmit data (TxD) signal.
Approx. 6mA
Power Down If the modem is on hook for 30 seconds,
it will automatically turn “off”.
The modem will automatically turn “on”
to full power within 400ms of receiving a
DTR signal or an incoming call.
Approx. 20µA
The power mode is set by a dip switch on the Pony Express Modem Module
inside the MIU case. Factory default is Power On mode. Other modes are set at
the factory before shipment if requested. Other modes can be set in the field ~
call Telenetics for an instruction sheet.

The MIU has a single LED that will indicate the following conditions...
4Blinking: POWER ON
4Steady: MODEM CONNECTED (CARRIER DETECT)
10. AUTO RESET FEATURE
The dial-up modem modules inside your MIU include an “Auto Reset”
feature: If the modem configuration is lost for any reason, it can be
restored by dialing the modem and allowing it to ring 4 to 6 times.
The Auto Reset feature is enabled and disabled by a dip switch on the
modem module. Your MIU will have been shipped with the Auto Reset
mode active, unless otherwise specified at the time of ordering. Please
consult Telenetics if you wish to open up your MIU to disable Auto
Reset.
11. AUTO DIAL FEATURE
The dial-up modem modules inside your MIU include a software
configured “Auto Dial” feature: Command AT\D1 will enable Auto
Dial: When DTR goes from an OFF to ON condition, and \D1 is set, the
modem will auto dial the phone number stored in location & Z0 (up to 45
digits).
Command \D0 (default) will disable the Auto Dial feature.

13. MODEM CONFIGURATION
Telenetics dial and leased line modems are based upon Rockwell
chipsets. These chipsets contain Rockwell’s “AT” command set.
A summary of the Rockwell command set for your MIU modem is
provided in Book 2.
Unless otherwise specified at the time of order, your modem will have
left the Telenetics factory in the configuration detailed on the following
pages.
The Telenetics factory configuration differs from the Rockwell default
configuration as follows...
&C0 Rockwell Default Carrier Detect (CD) always ON.
&C1 Telenetics Factory Carrier Detect (CD) only ON
when modem connected (on hook)
S0=0 Rockwell Default Auto-Answer OFF
S0=1 Telenetics Factory Auto-Answer on first ring
You can review the configuration of your modem by entering AT&V
<CR>.
You can restore the Rockwell factory configuration by entering
AT&F&W

15. DIAGNOSTICS
The following pages provide software and hardware techniques for
diagnosing communication problems and thereby isolating the problem at
either the local modem, the remote modem or the interconnecting line.
The following AT&Tn commands form part of the CCITT V.54 protocol
and can be used for diagnostic testing.
Note: &Tn commands can only be used when the modem is configured
for &Q0 <CR> (unbuffered/direct asynchronous mode).
