5.12 Analog Output
The SSP has two LEDs connected to the analog output channel. The yellow LED indicates positive
analog output voltages, while the green LED indicates negative analog output voltages.
The analog output can be set by the command
VO=level
where level is in millivolts in the range –10000 to 10000mV.
For example the command
VO=5000
will turn the yellow LED on to approximately half intensity, while
VO=-5000
will turn the green LED on to approximately half intensity. (Prog16.dxc)
BEGIN”Output”
1CV=-10000
RA100T
VO=1CV
1CV=1CV+100
END
5.13 Thermocouple
If you connected the thermocouple supplied with the DT800 to analog input channel 7, then the
temperature can be monitored by the command. (Prog17.dxc)
BEGIN”Temp”
RA1S
7TK
END
5.14 Scan Schedules
The SSP can be used to demonstrate several of the scan schedule triggers available in the DT800 as
follows:
•
5.14.1 Poll trigger by host (Prog18.dxc)
BEGIN”Poll”
P47=5
1SSPWR=1
RAX ‘Schedule triggers when host sends XA command
1V 3R 4PT385 5V
END
Send X or XA command from host PC (DeTransfer) to scan schedule
