TopKAT With 9800 Direct Connect
NOTES:
See TopKAT Direct Connect in the Cables section for point-to-point connections. When using an RS-232
termination box, connect a 1:1 cable (P/N C04654) between the PC and the termination box. Wire the
termination box to the Series 900 TopKAT as shown in the Installation Manual.
When operating a TopKAT in a master/satellite configuration, an RS-422 short haul modem (SHM) is
required for a direct connection between a PC and the TopKAT master. The RS-422 connection is made to
Port 3 at the TopKAT master. RS-422 GASBOY SHM wiring diagrams are available in the TopKAT
Installation Manuals.
