Using the Relay Matrix Switches 33
Chapter 2
Relay Matrix Switch Functions
This section provides some examples for Relay Matrix Switch module
functions, including:
•
Checking Module Identification
•
Switching Channels
•
Recalling and Saving States
•
Detecting Error Conditions
•
Synchronizing Relay Switch Modules
Checking Module
Identification
You can use the *RST, *CLS, *IDN?, CTYP?, and CDES? commands to
reset and identify the Relay Matrix Switch modules.
Example: Identifying
Relay Matrix Switch
Modules
This program uses the *RST, *CLS, *IDN?, CTYP?, and CDES? commands
to reset and identify the Relay Matrix Switch modules.
10 DIM A$[50]; B$[50], C$[50]
20 OUTPUT 70914; "*RST; *CLS; *IDN?"
30 ENTER 70914; A$
40 OUTPUT 70914; "SYST:CDES? 1"
50 ENTER 70914; B$
60 OUTPUT 70914; "SYST:CTYP? 1"
70 ENTER 70914; C$
80 PRINT A$
90 PRINT B$
100 PRINT C$
110 END
A typical return is:
HEWLETT-PACKARD,SWITCHBOX,0,A.04.00
4x16 2-WIRE MATRIX
HEWLETT-PACKARD,E1469A,0,A.04.00
Switching Channels
Use CLOSe <channel_list> to close one or more Relay Matrix Switch
channels, and OPEN <channel_list> to open the channel(s). channel_list
has the following forms.
For the E1468A only, the form is @ssrc where ss = card number (01-99)
r = row number (0 to 7 [one digit]) and c = column number (0 to 7 [one digit]).
For the E1469A only, the form is @ssrrcc where ss = card number (01-99)
rr = row number (00 to 03 [two digits]) and cc = column number (00 to 15
[two digits]).
To OPEN or CLOSe multiple channels, place a comma (,) between the
channel numbers. For example, to close channels 10103 and 10201,
execute CLOS 10103,10201. To OPEN or CLOSe a contiguous range of
channels, place a colon (:) between the first and last channel numbers.
