Multi-Link ICM User Manual

INTRODUCTION

The ICM, Internet Control Module, is a remote controller device accessible via the
Internet that allows operational access to the IPS (and other base units available).
Through the ICM you may choose settings for the base units and/or active their power
control operations. The settings and operational actions are presented in menu form on
the screen of the computer that accessed the ICM. The operator selects the appropriate
base unit from the menu. Then the operator only needs to choose the desired setting
options or the operational action desired for the appropriate device, and submit the
request (more details on section ).

FEATURES OF THE ICM

The ICM has an Ethernet port, an Analog port (not for phone line), and an RS-232 port.
The ICM is accessed via the Internet through the Ethernet port, by using an RJ-45
Ethernet cable (provided). The RS-232 port is normally used to communicate with the
“base unit”, and besides presenting options to set and execute commands through the
base unit, it also provides ability to interrogate the current status of base unit power (use
the serial cable provided for this type of communication).

The “Analog” port is used to communicate with a base unit when the base unit must be
separated from the controller by distances up to 2000’. In this is implementation you use
a RJ-11/14 type cable (two wires required) instead of the RS-232 connection. If
connecting the ICM with an IPS device, either Telco or Modem port of the IPS can be
used, but we recommend to use the port labeled “Modem”, so you have the flexibility to
also communicate with the IPS by a dial-up telephone connection for “Ring Count Power
Reset”. Without the RS-232 connection to the base unit there is no ability to interrogate
the power status of the base unit. NOTE: The “Analog“ port cannot be used for a
telephone line connection.

SETTING THE ICM

Connect the ICM to an Ethernet Local Area Network. Define what the IP address is going

to be (it must conform to your network’s structure). Also, on the back of the ICM, you
will find a MAC address, that you will need to enter when entering the new IP address.
There are four ways to assign an IP address to the ICM. They are:

1. Pinging a New IP Address method

• Open a Command prompt window;

- Go to "START" tab and select "RUN",

- Enter cmd.exe,

• From the cmd.exe window you can enter the base level commands

to “arp” (assign) and "ping" IP addresses. The arp and ping
commands will give a help display if you enter the command followed
by a –h. Examples;: ping –h, arp –h.

• Example to assign an IP address:

arp –s (new IP address) (ICM MAC address),

• Example to “communicate” (ping) with an IP address:,

ping (new IP address),

• These base level commands are normally entered in all lower case.

• Examples:

ping 10.10.10.140 (Tests the ability to communicate with the

addressed device…returns response time, usually in milliseconds)

arp –a (Returns a list of accessible IP addresses)
arp -s 10.10.10.140 00-03-75-0f-4c-45 (Assigns an IP address to

the provided “MAC” address)

• Once an IP address is set into the unit, it is "virtually permanent".

• The ICM can be reset (to return it to the original 0.0.0.0 address) by

the following process:

Un-plug power,
With the dip switches (at front of the unit) all down (Off) and
While holding the Reset button in (at the front of the unit),
Plug in power, still holding Reset button for 5 seconds,
This should leave the unit at original state.

2. Serial Connection Method

A terminal can be used to transmit a new IP address to the ICM. It can also
read the MAC and current IP addresses directly from the ICM. To do this,
follow this procedure:

• Connect the RS-232 cable to the serial port of the terminal and the

DB-9 of the ICM,

• Set Switch 1 up for direct serial control,

• Put the DCE/DTE slide switch (on back of the unit) to DCE,

• Set the terminal program’s COM port properties to 300 baud, 8 data

bits, No parity, and 2 stop bits,

• Direct the RS-232 commands using *?IP (displays the current IP

address), *EIP (displays the IP address in the EEPROM), *MAC
(displays the MAC address). *IPxxx.xxx.xxx.xxx# sets the IP address
to xxx.xxx.xxx.xxx, where xxx can be any number between 0 and 255
inclusive. This function also places the IP address into the EEPROM.

Note: These commands must be entered in upper case.

3. From Stored Memory Method

If DIP Switch 2 is up at power up, the ICM will use the IP address that is
saved in the EEPROM. Note: Even if the IP address is Factory Reset, the IP address in

the EEPROM will be used if Switch 2 is up at power up.

4. DHCP (Dynamic Host Configuration Protocol) Method
