1. Overview
This chapter presents the information how to use this manual and quick start if you
are already familiar with Microsoft Visual Studio and C# programming language.
1.1 Introduction
JYTEK PCIe/PXIe-6302 is a high-resolution temperature measurement module which
provides up to 32 channels, supports R/S/B/J/T/E/K/N/C/A type thermocouple, with
input voltage range of -78.125 mV ~ +78.125 mV and sample rate up to 800

1.4 Learn by Example
JYTEK has added Learn by Example in this manual. We provide many sample
programs for this device. You can download a JYPEDIA excel file from our web
www.jytek.com. Open JYPEDIA and search for JY6302 in the driver sheet, select
JY6302_Examples.zip. This will lead you to download the sample program for this
device. In addition to the download information, JYPEDIA also has a lot of other
valuable information, JYTEK highly recommends you use this file to obtain
information from JYTEK.
Figure 1 JYPEDIA Information
In a Learn by Example section, the sample program is in bold style such asWinform
AI Continuous; the property name in the sample program is also in bold style such as
SamplesToAcquire; the technical names used in the manual is in italic style such as
SampleRate. You can easily relate the property names in the example program with
the manual documentation.

In a Learn by Example section, the experiment is set up as follow. A PCIe/PXIe- 6302
card is plugged in a desktop computer. The PCIe/PXIe-6302 is connected to a TB-
68CJ terminal block.
Figure 2 TB- 68CJ terminal block.
The TB-68CJ has 4 terminal columns, J1 – J4 are shown below as Figure 3. In the rest
of this manual, the wire connection in each Learn by Example section will be given
by the pin numbers only.

2. Hardware Specifications
The 6302 is one of the family of temperature data acquisition module which provides
different interfaces, such as PCIe, PXIe, TXI(Thuderbolt) and USB buses (coming soon).
6302 on different interfaces is shown in Table 1.
Table 1 63xx on different buses
2.1 System Diagram
Figure 4 6302 System Block Diagram
Figure 4 shows the system diagram of the 6302. The system is mainly composed of
ADC, DDR and FPGA control modules. The FPGA-based driver code provides a stable
and efficient PCIe / PXIe / USB interface. 6302 has four ADCs, which can work alone
or together depending on channel configuration. Each ADC is responsible for the
measurement of one group of 8 channels and selects one of the 8 channels through
the multiplexer at the falling edge of AD conversion clock, as shown in Figure 22.
The channel grouping is shown in Table 2.

Table 2 6302 channel grouping
6302’s dedicated terminal block TB-68CJ has build-in temperature sensors for
measuring cold-juntion temperature to achieve cold-junction compensation (CJC).
* The terms "hot junction" and "cold junction" are used in this manual, which
also called "measuring junction" and "reference junction".
