SA Bus Terminal Block
The SA Bus terminal block is a brown, removable, 4-terminal plug that fits into a board-mounted jack.
Wire the removable SA Bus terminal block plugs on the lower port of the Dual Stacked Connector to the controller,
and other SA bus devices in a daisy-chain configuration using 4-wire twisted, shielded cable as shown in Figure 8.
See Table 5 for more information.
Figure 8: SA Bus Terminal Block Wiring
Note:
The SA BUS PWR terminal supplies 15 VDC. The SA BUS PWR terminal can be used to connect (daisy
chain) the 15 VDC power leads on the SA Bus.
