SC-2345 Carrier with Configurable Connectors

The SC-2345 with Configurable Connectors is electrically and

functionally identical to the SC-2345 connector block. The only

differences are the orientation of some modules and the addition of

I/O connector and interface panelettes. This carrier is available with

either a side 68-pin connector (recommended for DAQCard products)

or a rear 68-pin connector (recommended for DAQPad products).

The SC-2345 with Configurable Connectors handles dual-stage

conditioning and digital I/O modules. It also offers custom

connectivity by adding panelettes along its front and rear panels.

Select up to 18 panelettes for side-mount 68-pin versions, or

15 panelettes for rear-mount 68-pin versions. With I/O panelettes,

you can connect your sensor directly to the SCC system. With

interface panelettes, you can add hardware controls and displays to

your system. Blank panelettes are also available to fill unused

positions or for modification to fit your custom application needs.

SC-2350

The SC-2350 includes 10 SCC module sockets, labeled J1 through J8,

J17, and J18 (see Figure 3). Sockets J1 through J8 accommodate SCC

modules for conditioning signals on the analog input channels of the

DAQ device. For example, an SCC module plugged into socket J1

would condition signals for channels 0 and 8 of the device. You can

use sockets J17 and J18 for SCC modules that condition analog

signals on the output channels of the DAQ device.

The SC-2350 contains a TEDS microcontroller with two digital

lines per analog input channel for communication with Class II

smart TEDS sensors (for more information on smart TEDS sensors

The IEEE 1451.4 standard delivers plug-and-play capability to

analog sensors. End users, systems integrators, and developers can

automate the configuation of measurement systems for analog

sensors. By defining an easy add-on approach that brings TEDS

benefits to all types of sensors, the standard makes data acquisition

systems easier to set up, configure, and maintain. The TEDS

structure is compact and flexible enough to handle a very wide range

of sensor requirements.

Smart TEDS Sensors

An IEEE 1451.4 smart TEDS sensor consists of the analog

components and an embedded memory chip, which together provide

the mixed-mode interface for analog and digital signals. A smart

TEDS sensor identifies and describes itself – providing the

manufacturer, sensor model number, serial number, measurement

range, sensitivity, and calibration information. TEDS information

resides on a memory chip (EEPROM) within the sensor and is

accessed by measurement systems such as the SC-2350 via a simple

low-cost serial interface.
