SERIAL LINK SERIAL LINK SERIAL LINK SERIAL LINK SERIAL LINK
The device can be connected to a host computer by a serial
link.
The host can put the device in LOCAL (functions and parameters
are controlled via keyboard) or in REMOTE (functions and
parameters are controlled via serial link).
The REMOTE status is signalled by the REM LED.
This instrument allows to modify the operative and configuration
parameters, via serial link.
The necessary conditions to implement this function are the
following:
1) the serial parameters (see Run time group 7) should be
properly configured.
2) the device must be in the run time mode.
3) when it is desired to modify configuration parameter, the dip
switch V101.3 should be set to "OFF" (configuration parameter
enabled)
During configuration parameter downloading the device goes in
open loop with all output in OFF state.
At the end of configuration procedure, the device performs an
automatic reset and then returns to close loop control.

When it is desired to verify the display efficiency, put the
instrument in "normal display mode" and push and MENU
push-buttons for more than 5 s.
The instrument will turn ON, with a 50 % duty cycle, all the LEDs
of the display (we define this function "LAMP TEST").
No time out is applied to the LAMP TEST.
When it is desired to come back to the normal display mode,
push any push-button.
During the LAMP TEST the instrument continues to control the
process.
