    C-Size VXIbus mainframe using a command module (such as an E1406A Command Module). Multiplexer Components The E1460A 64-Channel Relay Multiplexer module consists of a relay switch card and a standard screw-type terminal module. The E1460A is also available with Option A3E that provides a crimp-and-insert terminal housing and connectors.

  • Page 13: Channel Relay Switches

    The channel relay switches are separated into eight banks. Each bank has eight switchable channels and a COM channel. Each channel has a separate HI (H) and LO (L) line. See Figure 1-1 for a block diagram. Figure 2-1 E1460A Multiplexer Block Diagram Keysight E1460A 64-Channel Relay Multiplexer User Guide...

  • Page 18: Setting The Logical Address Switch

    The instrument logical address (LADDR) is set with the logical address switch located on the instrument. The logical address switch (LADDR) factory setting for the E1460A is 112. Valid address values are from 1 to 255. See Figure 1-2 to set the logical address. From Figure 1-2, note that the value of the logical address set is the sum of the values of the switches set to the CLOSED position.
