1. Introduction
The i-7000 series is a family of network data acquisition
and control modules, providing analog-to-digital, digital-
to-analog, digital input/output, timer/counter and other
functions. The modules can be remotely controlled using a
set of commands, which we call the DCON protocol.
Communication between the module and the host is in
ASCII format via an RS-485 bi-directional serial bus
standard. Baud Rates are software programmable and
transmission speeds of up to 115.2 Kbps can be selected.
Some i-7000 modules feature
a new design for the frame
ground and INIT switch as
shown in the figure (rear
view). The frame ground
provides enhanced static
protection (ESD) abilities and
ensures the module is more
reliable. The INIT switch
allows easier access to INIT
mode. Please refer to Sections
A.1 and A.3 for more details.
The common features of the i-7005 and M-7005 modules
are as follows:
1. 24-bit sigma-delta ADC to provide excellent accuracy
2. Direct thermistor connection
3. Software calibration
The i-7005/M-7005 is an 8-channel thermistor input and
6-channel digital output module
i-7005/M-7005 User’s Manual, Rev: B1.8 7MH-018-B18 5

Supported thermistor types are as follows:
1. PreCon Type III, Model 3, 10,000 Ohms at 25°C (77°F)
2. Fenwell Type U, 2000 Ohms at 25°C
3. YSI L Mix, 100 Ohms at 25°C
4. YSI L Mix, 300 Ohms at 25°C
5. YSI L Mix, 1000 Ohms at 25°C
6. YSI B Mix, 2252 Ohms at 25°C
7. YSI B Mix, 3000 Ohms at 25°C
8. YSI B Mix, 5000 Ohms at 25°C
9. YSI B Mix, 6000 Ohms at 25°C
10.YSI B Mix, 10000 Ohms at 25°C
11.YSI H Mix, 10000 Ohms at 25°C
12.YSI H Mix, 30000 Ohms at 25°C
