Introduction
The 6224 is a twelve-channel, 24-bit resolution strain measurement device that connects to a host PC‟s Ethernet
port. The device is used to measure half-bridge and full-bridge sensors and can be synchronized with other 6000
series devices.
The hardware provides the signal conditioning and acquisition engine, while the software defines the specific
configuration and analysis aspects of the system.
Note that the software includes both a context sensitive Help and a comprehensive Help file.

Front Panel
The front panel houses twelve channel signal input jacks and
three excitation voltage source connectors, one for each set of
four channels.
The input channel jacks are type RJ50 (10p10c) and are labeled
CH1 through CH12. The 10-connector pinout for the RJ50
connectors is included in chapter 3.
Optional external voltage source connectors are available. For
additional information see the External Excitation Voltage
Sources section of chapter 3.
Do not connect an RJ45 plug to an RJ50 jack. Using RJ45 plugs can cause
permanent damage to RJ50 pins 1 and 10, thus disabling shunt calibration.
