E1468A Relay Matrix
Switch Channel
Addresses
For the E1468A Relay Matrix Switch module, the channel address
(
channel_list ) has the form (@ssrc) where ss = card number (01-99), 
r = row number, and c = column number. E1468A Relay Matrix Switch
module channel numbers are r = 0 to 7 (one digit) and c = 0 to 7 (one digit).
You can address single channels (@ssrc); multiple channels
(@ssrc,ssrc,...); sequential channels (@ssrc:ssrc); groups of sequential
channels; @ssrc:ssrc,ssrc:ssrc); or any combination. For example, CLOS
(@124) closes row 2, column 4 of card 01 of an E1468A Relay Matrix Switch
module.
Only valid channels can be accessed in a channel list or channel range.
Also, the channel list or channel range must be from a lower channel number
to a higher channel number. For example, CLOS (@100:233) is acceptable,
but CLOS (@233:100) generates an error.
E1469A Relay Matrix
Switch Channel
Addresses
For the E1469A Relay Matrix Switch module, the channel address
(
channel_list ) has the form (@ssrrcc) where ss = card number (01-99), 
rr = row number, and cc = column number. E1469A 4 x 16 Relay Matrix
Switch module channel numbers are rr = 00 to 03 (two digits) and cc =

00 to 15 (two digits).
You can address single channels (@ssrrcc); multiple channels
@ssrrcc,ssrrcc,...); sequential channels (@ssrrcc:ssrrcc); groups of
sequential channels (@ssrrcc:ssrrcc,ssrrcc:ssrrcc); or any combination.

For example, CLOS (@10214) closes row 02, column 14 of card 01 of an
E1469A Relay Matrix Switch module.
Only valid channels can be accessed in a channel list or channel range.
Also, the channel list or channel range must be from a lower channel number
to a higher channel number. For example, CLOS (@10000:20303) is
acceptable, but CLOS (@20303:10000) generates an error.
Initial Operation An example program follows that uses BASIC and SCPI language to help
get you started using the Relay Matrix Switch modules. The example
assumes a GPIB interface. The program closes row 03, column 12 of an
E1469A 4 x 16 Relay Matrix Switch module at logical address 112
(secondary address = 112/8 = 14) and queries the result. The result is
returned to the controller and displayed (1 = relay closed, 0 = relay open).
10 OUTPUT 70914; "*RST"
!Reset the module. Set

!all relays to open.
20 OUTPUT 70914; "CLOS (@10312)"
!Close channel row 03,
!column 12 on the first
module in the switchbox
30 OUTPUT 70914; "CLOS? (@10312)"
!Query channel
40 ENTER 70914; Value
!Enter result
50 PRINT Value
!Print results
