  • Page 22: Switch Module Architecture

    SWITCH MODULE ARCHITECTURE The 40-754 modules is an array of 9 or 17 uncommitted SPDT RF relays. In the default state, all signal paths are between the C terminal and the corresponding NC terminal. Energising a particular relay breaks the C to NC connection and creates a path between the C and NO terminals.

    Once the drivers are installed the manual “Sys40Prg.pdf” and driver help files which fully describes these functions can be found in the Pickering folder(s) or the Pickering entries on your Start Menu. The card must be opened before use and closed after using the following function calls: Direct I/O Driver - Open with PIL_OpenCards or PIL_OpenSpecifiedCard and close with PIL_CloseCards or PIL_CloseSpecifiedCards respectively.
