Chapter 7: sDIO Module Labeling Cables The X3 and X4 input connectors on the front of the sDIO module are similar except that X3 handles the group 1 and group 2 input signals and X4 handles the group 3 and group 4 input signals. The optional digital input cables can be connected to either X3 or X4. Make sure to clearly label the cables once you have completed your installation so that the cables do not get swapped by mistake. See the warning that follows. The X1 and X2 output connectors are also similar except that X1 handles the group 1 and group 2 output signals and X2 handles the group 3 and group 4 output signals. The optional digital output cables can be connected to either X1 or X2.
Make sure to clearly label the cables once you have completed your installation so that the cables do not get swapped by mistake. See the warning that follows. WARNING: Clearly label the X1 to X4 digital I/O cables so that they are always plugged into the correct connectors. Swapping the X3 and X4 or X1 and X2 cables could cause damage to your equipment. Depending on the installation, this could potentially cause injury to personnel in the area. Input and Output Cable Wiring Information The pinouts, signal names, and wire color information for the input and output cables are shown in the next four tables. Table 7-5.
