MODEL 1120 REMOTE EMULATION OPTION
Background
The Model 1120 Remote Emulation option was developed for those customers who have been
controlling their Model 1120's on a GPIB bus with dedicated programming. The Model 1120
Remote Emulation mode allows them to connect the Model 1140A to their existing systems and
have the Model 1140A function in those systems. Ectron does not recommend writing new code
for the Model 1140A using the Model 1120 Emulation mode.
While the Model 1120 was controlled remotely with either GPIB or RS-232, the Model 1140A
can be controlled by Ethernet and USB as well in the Model 1120 Remote Emulation mode. It is
anticipated by Ectron that customers who require the this option will be using GPIB.
Limitations
When a Model 1140A is equipped with the Model 1120 Remote Emulation option, and it is
ENABLED, the Model 1140A will respond to Model 1120 remote commands with certain
limitations as described below.
Packet Delimiter
The Models 1120 and 1140A both detect the EOI GPIB bus flag as a packet delimiter. In
addition, the Model 1140A also treats carriage return and newline characters as packet delimiters.
This is only significant if remotely editing output values over multiple packets (see below).
Command Processing
The Model 1120 processes commands sequentially regardless of whether they were received
over the remote interface or entered at the front panel. This allows users to send parts of
command strings over the remote interface and interleave commands from the front panel. The
Model 1120 Remote Emulation mode on the Model 1140A does not support this feature, and
does not interpret front-panel keys in the same way as remote characters. Thus remote commands
and front-panel keys cannot be interleaved.
