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.
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. MIU Installation, Operation & Diagnostics...
POWER CONNECTIONS DC Power Jack, 2.0mm – This standard concentric jack is provided to attach an external power source in the range of 7 – 16 VAC or 8 – 24 VDC. The 2.0mm Jack connects through a full wave bridge so either polarity is acceptable from the DC source.
DIP SWITCH SETTINGS Not Applicable – The dip switches are on the PE Module. Contact factory for non – standard settings. * NOTE: Opening the MIU for any reason voids the factory warranty. MIU Installation, Operation & Diagnostics Edition: January 25, 1999 Page 10...
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. AUTO DIAL FEATURE The dial-up modem modules inside your MIU include a software configured “Auto Dial”...
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.
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.

&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.
&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.
Page 23
&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). &T6 INITIATE REMOTE DIGITAL LOOPBACK (See Figure 4) The command is valid only if the modem is in the command state with a...
This is a system test, end to end. The command is valid only if the modems are in the command state with a connection established. Configure the remote modem with an AT&T4 command so that it will honor a remote digital loopback request. Enter AT&T7 at the local modem and it will send a digital loopback request to the remote modem.
Page 25
&T8 LOCAL LOOPBACK WITH SELF TEST (See Figure 6) The modem should be on hook. Enter AT&T8 to configure the modem for analog loopback and self test. The test timer is started at the time indicated by S18, DSR is turned off (if &S1 is in effect). A self test condition is entered, and an OK result code is sent to the DTE.

ADDITIONAL TEST / DIAGNOSTICS COMMANDS... RECEIVED SIGNAL LEVEL Returns a value (-dBm) which indicates the received signal level at modem DATA PUMP interface. This value is determined by the loss/gain of modem Telco Interface circuit ±dB at the Tip/Ring input to the modem. Typical value should be -25dBm to -35dBm for most Telco connections.
