9.3 SSCA Simplex Serial Communication Input/Output

9.3.1 Functional Description
The Simplex Serial Communication Input/Output (IS410SSCAH2A) terminal board is a compact serial communication
terminal board that provides up to six communication channels. Each channel may be configured for RS-232C, RS-485, or
RS-422 signaling. The I/O pack plugs into the DC-62 pin connector to communicate with the Mark VIe controller over
Ethernet.
9.3.2 Installation
The SSCA is DIN-rail mounted using a sheet metal carrier and plastic insulator mount. This assembly will also bolt directly
into a cabinet. SSCAH2 has a right-angle header accepting a range of commercially available pluggable terminal blocks, with
48 terminals.
Note There is no shield termination strip with this design.
Typically, the SSCA uses #18 AWG (shielded twisted pair) wiring. The I/O cable shield termination is on an external
mounting bracket supplied by the customer or by GE. The chassis ground connection uses E1 and E2 as mounting holes. One
of the SCOM terminals (37-48) must be connected to a suitable shield ground.
