Programming over RS-232
Information is stored in bytes (8 bits at a time) in the switch. Data can be sent
and received just as it is stored, without the need to convert the data.
Communicating
over the RS-232
interface
Each RS-232 interface card has its own interface select code. This code is
used by the controller to direct commands and communications to the proper
interface. Unlike HP-IB, which allows multiple devices to be connected
through a single interface card, RS-232 is only connected between two devices
at a time through the same interface card. Because of this, only the interface
code is required for the device address.
Generally, the interface select code can be any decimal value between 0 and
31, except for those interface codes which are reserved by the controller for
internal peripherals and other internal interfaces. This value can be selected
through switches on the interface card. For more information, refer to the ref-
erence manual for your interface card or controller.
RS-232 commands
RS-232 control of the switch is initiated by sending the OPEN RS232 COM
command over the interface. This places the switch in the remote mode and
locks out the front panel. Pressing the
LOCAL
key will bring the instrument
back to local mode.
Many of the commands used for controlling the switch and for retrieving data
from the switch are the same as for the HP-IB interface. Refer to the individual
command descriptions to determine if the command applies to both HP-IB
and RS-232.
To end communications with the switch over the RS-232 interface, send the
CLOSE RS232 COM command. This command returns control to the front
panel of the instrument.
