14.4.1 Capability
The 3560 GPIB interface conforms to standard IEEE-488.2, 1992. Its capabili
-
ties are identified as SH1, AH1, T6, L4, SR1, DC1, and E2. The interface has
the capabilities of talk, listen, serial poll, and device clear. It has no capability
for talk-only, listen-only, extended talk or listen, parallel poll, remote-local con
-
trol, or trigger, nor can it act as controller. The IEEE-488 commands GET,
GTL, LLO, and REN are accepted without error but ignored.
14.4.2 Connection
The IEEE-488 port is located on the back of the 3560 Module. Use a standard
IEEE-488 cable to connect to your GPIB controller. A shielded cable should be
used to prevent EM emissions.
14.4.3 Device Setup
The 1560 system must be set up to respond to the address the controller will
use to communicate with it. The address is set using the SET UP DEVICE
function in the MODULE soft-key menu (see Section 5.4.2). Select the GPIB
device. A window appears showing the setup parameters for the device:
SET UP DEVICE: GPIB
ADDRESS: 22
TERMINATION: LF
RESET: NO
For the 3560 GPIB Communication Device the list of parameters includes ad
-
dress, line termination, and interface reset function. The default address is 22.
The valid range is 1 to 30. The address will remain unchanged if an attempt is
made to set the address outside this range. Use the numeric buttons to change
the address, if necessary, and press ENTER. The new address will take effect
immediately.
The TERMINATION parameter is used to set the line termination character for
IEEE-488 communications. This should normally be set to LF which causes a
linefeed character (ASCII 0A hex or 10 decimal) to be sent at the end of each
line of transmission. If necessary, this can be changed to a carriage return char
-
acter (ASCII 0D hex or 13 decimal). The termination is changed using the
LR buttons and pressing ENTER.
