Introduction

The EXACTUS®Industrial Mux (IFM8-IA or IFM8-I) is designed as a data transport device

allowing communication between a host system and up to eight pyrometers. In most situations,

the Industrial Mux can be connected and operate without any setup or configuration changes.

Some of the features that can be configured on Industrial Mux include:

Activation of the analog outputs.

Activation of an instrument monitoring system which detects, and alarms, if any instrument

should fail or otherwise stop communicating.

Configuration of settings which will power down the pyrometer electronics, should their

internal temperature become too high or too low.

Adjustment of pyrometer voltage to compensate for excessive cable resistance.

interfaces for external equipment: current loop (isolated 0-20mA, 16 bit, 8 channels), RS-485

(isolated, 960K), Ethernet (dual 10/100 Mb/s.), and 2 relays (each NO/COM/NC).

relays are only active during an error condition. When active, the system shuts down power to

the pyrometers causing power consumption to drop.

TCP/IP Ports

The Industrial Mux has two RJ-45 Ethernet connectors, but only one MAC address and one

TCP/IP address. The ports function as two ports on a switch. Packets entering one connector and

not bound for the IFM8-IA are passed to the other connector, thus the IFM8-IA can be daisy-

chained.

3. Default Parameters

The Exactus® Industrial Mux ships with the following default parameters:

Analog output is enabled. Note: Not all Industrial Mux units will include analog outputs.

(Only Model number IFM8-IA include the analog output ports)

Temperature alarm is set to power down all pyrometers when any pyrometer electronics

temperature drops below 0ºC (32ºF) or goes above 75ºC (167ºF).

The coil for Relay 1 is programmed to energize if the pyrometer temperature limits are

exceeded. Pyrometers will remain powered down until power to the Industrial Mux is cycled

off and back on.

The Pyrometer Supply Voltage is set to 6200mV – adequate for standard pyrometer

power/communication cables up to 15 meters (49 ft).

Note: If these defaults are adequate, no further configuration is necessary.

4. Configuration Communication

If configuration of the Industrial Mux is necessary, a program such as HyperTerminal which is

included with some versions of Microsoft®Windows, can be used. Some versions of the

Exactus® TemperaSure® software include a ‘Configure Mux’ menu in the Advanced Mode of

operation (see figure 4-0).

Figure 4-0: Configure Mux option

The following instructions are written for setting up HyperTerminal on Windows XP. Similar

steps can be used for other versions of Windows.

1. Connect a CAT5 cable to either of the ports LAN1 or LAN2 and to an Ethernet input on

the computer. The cable can be of any LAN type.

2. Set the IP address of the PC:

a. Right-click on My Network Places and choose ‘Properties’ from the pop-up menu.

See Figure 4-1.

Figure 4-1: Selecting Properties of My Network Places

b. Double-click on the connection. If there is more than one connection, you can

determine which connection to use by unplugging the LAN cable from the Mux,

and the Status will change to “Network Cable Unplugged”. See Figure 4-2.

Figure 4-2: Network Connections Screen

c. The following screen (Figure 4-3) will appear. Click the ‘Properties’ button.
