Page 31: Connection Of Remote I/O
Connection of Remote I/O One 9-pin D sub-miniature female connector is mounted on the rear panel that provides REMOTE-INPUT control and information. This connector mates with standard 9-pin D-sub-miniature connector provided by the user. The female (socket) connector on the power source mates to a male (plug) connector. For best performance, a shielded cable should be used. -
