RJ50 12-Pin Screw Terminal Accessory (CN-268)
This accessory is used for Half-Bridge or Full-Bridge completion. Because bridge
completion is built into the 6224, you will only need connectivity accessories.
The CN-268 is a set of four female RJ50 to 12-pin screw terminal adapters. You
will need an RJ50 M/M cable to use a CN-268 component with an 6224.
Measurement Computing offers a pack of four RJ50 M/M, 1 meter (3.28ft) cables
(see following RJ50 Cables section).
As indicated in the right-hand figure below, CN-269 and CN-270 components each have two holes that can be used to
loop a plastic tie-strap through, as a means of adding strain relief for the wire connections to the screw terminals.
If you want to mount a CN-268 component, use an M4x20 screw (or similar hardware) that can fit into the 8.89 mm
(0.350 in.) outer clearance/4.57 mm (0.180 in.) inner clearance hole. See figure.

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.
RJ50 Cables (CA-272-01)
When connecting a cable from an 6224 RJ50 jack to an associated Measurement Computing accessory (CN-268, CN-269,
or CN-270), be sure to only use RJ50 M/M cables. Use of another cable type can damage RJ50 pins.
The CA-272-01 includes four RJ50 to RJ50 M/M, 1 meter (3.28ft) cables.
