1.1 Digital and Analog Interface Modules
The IFD-5 Digital Interface Module allows the pyrometer to be connected to any PC. This
module also isolates the electronics from any electrical noise and supplies a regulated power
supply to the pyrometer. There are three connections on the IFD-5 Module: on one side of the
module is a RJ45 connector for the pyrometer cable and a female DB9 connector for the host
computer. On the opposite side of the module is the connection for the power supply. The
interface module has a green LED that indicates when power is being applied.
The pyrometer can communicate with a host computer using either RS-232 or RS-422 serial
communication. If it is configured for RS-232 than the interface module should be connected to
the PC or digital data logger with a cable no longer than 15 meters.
BASF also offers an analog output option, the EXACTUS IFA-5, which can be configured to
either a voltage or current output. The value of the analog output can be scaled as needed using
the TemperaSure
®
software from 0 to 10 volts or 0 to 20 mA for the desired temperature range.
1.2 Power Supply
A single channel system is powered with a DC Power Supply through the IFD-5 Digital Interface
Module as shown in Fig 1.0. The IFD-5 Module may be powered by any DC voltage between 12
and 24VDC. The IFD-5 supplies power for the electronics and optional IFA-5 analog module.
1.3 Software Interface
EXACTUS TemperaSure
®
graphical user software gives the user the ability to log and/or display
temperature readings and configure the pyrometer and IFA-5 module user settings. Refer to the
EXACTUS Optical Thermometer user manual on how to install and set up the software.
2.0 IFD-5 Digital Interface Module
Using the IFD-5 interface box, the EXACTUS pyrometer can communicate digitally, selectable
for either RS232 or RS422 line levels. The IFD-5 provides power to the pyrometer and isolation
of the communication lines. The Modbus and EXACTUS protocols are available using this
interface.
To connect the pyrometer to a standard PC serial port using the IFD-5, make sure that the
selector switch for RS232/RS422 is in the RS232 position. This is a small single DIP switch
near the IFD-5’s DB-9 connector.
