2. PRODUCT OVERVIEW
The MIUPowerPortX.X Series are industrial grade dial and leased line 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 +85º 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
Raymar-Telenetics™ Pony Express™ Dial Modem Module.
The MIU PowerPort is packaged specifically for the harsh environments found in utility
substations, industrial facilities and remote sites. Though functionally similar to commercial
modems, the MIU PowerPort includes special features that make it particularly well suited for
utility and industrial applications.
Environment: The MIU PowerPort 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 PowerPort can be powered from a range of AC and DC power
sources: +5 VDC, 12 VDC Battery, 7 to 16 VAC or 8 to 16 VDC. An
optional 120 VAC wall transformer is available from Raymar-Telenetics.
Low Power: The MIU PowerPort dial modems can be configured to enter into a
“power down” mode. In this mode, an MIU PowerPort will consume only
a small fraction of its active power while waiting for either controller or
telephone line activity.
Industrial: The MIU PowerPort 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 to increase reliability and decrease power
consumption. 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 Raymar-Telenetics for an instruction sheet.

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).
&T0 TERMINATE TEST IN PROGRESS
If a V.54 loopback test is in progress as a result of executing an &Tn command, then the &T0
command will cause that test to be terminated, provided that the modem is in the command state or
a V.54 state that accepts commands from the DTE. See specific &Tn command descriptions for
termination actions.
&T1 INITIATE LOCAL ANALOG LOOPBACK (See Figure 2)
When the AT&T1 command is entered, the modem goes on hook and configures itself for analog
loopback. DSR is turned off (if &S1 is in effect), the analog loopback state is entered, and the test
timer is set to the value in S18. A connect result code is sent to the DTE, and the test timer then
begins its count down. The test terminates when the test timer expires. If S18 equals 0, then the
test must be terminated by an &T0, H0, or Z command. While any command may be entered
while the modem is in this test state, the modem response is not specified except for H0, &T0 and
Z, any of which will terminate the test. Upon termination of the test, the modem enters the
command state.
RESULT CODE DESCRIPTION
CONNECT When local analog loopback state is entered.
ERROR If any other &Tn test is active (except &T0) or if in the on-line command
state.
OK After test is stopped by test timer, the H0 command, or the &T0
command.

0049-0300-XXX MIU/Power Port Series – USER GUIDE 08/04/2010
Rev. A Page 16 of 26
&T2 NO FUNCTION
&T3 PERFORM LOCAL DIGITAL LOOPBACK (See Figure 3)
The modem must be in the command state with connection established when this command is
issued, otherwise an ERROR result code occurs.
The AT&T3 command establishes a loopback of received data, after demodulation, and sends it
back to the distant end. The modem is configured for local digital loopback, DSR is turned off (if
&S1 is in effect), the test timer is started with the value in S18, and an OK result code is sent to the
DTE. If S18 contains a 0, the test must be terminated by a &T0, H0, or Z command. The latter
two result in the modem going on hook. If S18 does not contain 0, the test is terminated after the
number of seconds stored in S18.
RESULT CODE DESCRIPTION
OK After 2 second delay
ERROR If any other self test is active (&T1, &T6, &T7 or &T8) or if in idle state.
When test is terminated.
&T4 GRANT REMOTE DIGITAL LOOPBACK (RDL) REQUESTS
When in the on-line state, the modem will honor a remote digital loopback request from a distant
modem if it occurs. This will result in an ERROR if the command is given while any V.54 test is
active (&T1, &T3, &T6, &T7 or &T8).
NOTE: There are data patterns that may cause a Remote Digital Loopback conditions. Care
should be given to the type of data being received so that no RDL modes will be initiated.
&T5 DENY RDL REQUESTS
The modem will not respond to a remote digital loopback request from a distant modem. This will
result in an error if the command is given while any V.54 test is active (&T1, &T3, &T6, &T7 or
&T8).
