Operation
Operating instructions
To select an input channel, the Model 7001 must close two switches at the same time. Table 2-1 lists which Model 7020-MWS
digital outputs must be activated to select each respective RF input. The table also shows 7001 channels used to select the inputs.

Output patterns for each input are stored in the Model 7001 memory at the factory. The user can call up memory locations to
select each input. For example, calling up memory location 1 selects input 1. Some programming examples are listed below.
PRINT #1,"output 7; :close (@ 1!1,1!21)"
PRINT #1,"output 7; :close (@ M1)"
For further information on operation and programming, refer to the Models 7001 and 7020 Instruction Manuals.

NOTE
Information stored in non-volatile memory will be lost if power is applied to the switch
mainframe when switch cards, such as the 7020-MWS, have been removed. To assure mem-
ory remains as factory programmed, never power up the mainframe with a switch card re-
moved.
In either configuration of the Model 7116-MWS, as one 1 × 16 multiplexer or, with the semi-
rigid jumper cables removed, as five 1 × 4 multiplexers, ensure that only one channel is
closed per relay, and that no more than two relays are energized simultaneously per bank.
