1. Main Features
Very High Speed & High Resolution.
Supports up to 8 channels (differential inputs).
Each channel can be set for a thermocouple reading or
for a voltage (millivolt) reading.
Internal A/D resolution: 24 bit (not all are used).
Sampling rate: 400 Hz (50 Hz for each channel).
Single opto-isolated output per channel which can be
used as a set-point (alarm etc.) or as a general purpose output.
Conversion tables are on board to enable stand-alone operation.
Reading is in °F, °C or mV.
CJC (Cold Junction Compensation) built on board.
Each channel supports the most popular families of
thermocouples (E, J, K, R, S, T) or any indefinite voltage source in the range -500mV -> +500mV.
USB as a standard method of communication.
USB + RS485 and RS232 (option).
Multiple boards may be connected via USB or the
optional RS485.
On board high accuracy reference voltage for easy calibration.
No need for external power supply when used with USB.
Includes Windows software for initial setup and also a
Smart data logger package for monitoring & collecting readings in high speed – with graphic mode display.
Communication
Two types of drivers are available:
The direct driver provides access via a DLL supplying functions to directly control the device.
The VCP (Virtual COM Port) driver would make the TCIC appear as a spare COM port on the PC, e.g. COM3.

2. Installation
(The following description refers to Windows XP. Obviously, on another operating system it might be different.)
1. Make sure that all package files have been copied – and unzipped if necessary – to your hard disk.
2. Two types of drivers are available. Install the one that meets best your requirements. Note that only one
driver may be installed at the same time. That is, if
for some reason you want to switch to the other driver, first uninstall the retired one.
The direct driver provides access via a DLL supplying
functions to directly control the device.
The VCP (Virtual COM Port) driver would make the
TCIC appear as a spare COM port on the PC, e.g.
COM3. Consider which driver is best for you and proceed accordingly to step 3 or 4.
3. Installing the Direct DLL Driver:
3.1 If the VCP (Virtual COM Port) Driver is installed, uninstall it as follows: Click: Start – Control Panel – Add or Remove Programs – FTDI USB Serial Converter Drivers – Change/Remove
Disconnect all TCIC boards from the USB port and click Continue…

Click Finish.
3.2 Disconnect or disable the internet communication if such exists. The reason for that is that there are cases where the installation procedure automatically communicates with manufacturer’s site, which might lead to wrong operation.
3.3 Connect the TCIC card to your PC.
3.4 The ‘Found New Hardware Wizard’ appears. Select the last option like this:

Disconnect all TCIC boards from the USB port and click Continue…
Click Finish.
4.2 Connect the TCIC card to your PC.

Notes
1. It might occur that the wizard will return to step 4.3, requiring to repeat the process. This is normal, just repeat steps 4.3-4.6.
2. The package includes also an RS232 terminal found on the Web, called Termite, through which the TCIC may be communicated when the VCP driver is installed. Termite (http://www.compuphase.com/software_termite.htm) is freeware, yet it is easy to use and easy to configure. TCIC communication parameters are: Baud Rate: 115,200; Data: 8 bits; Parity: None; Stop Bits: 1.
