Banks are arranged as follows:
• Bank 0 includes channels 00 through 07 and COM
• Bank 1 includes channels 10 through 17 and COM
• Bank 2 includes channels 20 through 27 and COM
• Bank 3 includes channels 30 through 37 and COM
• Bank 4 includes channels 40 through 47 and COM
• Bank 5 includes channels 50 through 57 and COM
• Bank 6 includes channels 60 through 67 and COM
• Bank 7 includes channels 70 through 77 and COM
Each channel is switched (connected to its common) by closing the
appropriate (latching) relays. Channels 0 through 7 can be switched to

COM for all banks. Any number of channels in each bank can be connected
to common at a time (except for one-wire mode).
User inputs/outputs to each channel are via wire terminals. When a channel
is closed, it is internally connected to the COM terminal. When a channel is
opened, it is internally disconnected. Open channels are not terminated.
At power-on or reset, all channels are switched open (non-terminated) for all
banks only when using the SCPI or C-SCPI driver. At power-off, all relays
remain in their present state.
Control Relays In addition to the channel switching relays, the switch card contains seven
control relays (numbered 0990 to 0996). These relays switch the COM lines
of banks dependent on the mode selected. All relays are automatically
selected when the module is configured for the desired mode, when using
the [ROUTe:]FUNCtion <
card_number> , < function> command.
For the stand-alone switchbox configuration, this command must be used in
conjunction with the following commands. If you only use [ROUTe:]OPEN
and [ROUTe:]CLOSe commands, the appropriate control relays must also

be closed with the CLOSe command.
[ROUTe:]SCAN:MODE mode
[ROUTe:]SCAN:PORT
[ROUTe:]SCAN channel_list
For the scanning multimeter configuration, [ROUTe:]FUNCtion
<
card_number >, < function > in conjunction with the CONFigure and
INITiate or MEASure multimeter commands closes the appropriate control
relays. See Chapter 3 in this manual and Chapter 5 in the E1326B/E1411B
User’s Manual for more information about these commands. Table 1-1
shows the control relay functions.
