To return to program mode, press CANCEL and test mode will end.
When in manual simulation, by default test mode will move the level by
0.328 feet steps. Altering the increment (P*981) will change this value.
In automatic mode, the rate at which the level moves up and down is set by
the increment (P*981 in feet, the rate (P*982) in minutes, which can be
changed to make the level move up and down faster. E.g. if increment
(P*981) is set for 0.1m and rate (P*982) is set to 1 min then the level will
increase or decrease at a rate of 0.1m/min. To make the simulated level
move slower, decrease the value in increment (P*981) or increase the value
in rate (P982). To make the simulated level move faster, increase the value
in increment (P981) or decrease the value in rate (P*982).
Using the RS232 Serial Interface
The RS232 serial interface is used to communicate between the Ultra Twin
and a PC using the optional Ultra PC and other associated Pulsar software
packages, to obtain information such as data logging and view echo traces
upload, download and save parameter files. In addition it can also be used to
control or obtain information using a standard PC or other computer base
equipment. To do so, the settings for control are as follows: baud rate
19,200, 8 data bits, no parity, 1 stop bits.
The device should be connected via the serial port, as shown in Chapter 2
Installation.
To use the device remotely, you need to log on to start, and log off when
finished. When logged on, Ultra Twin will show ‘Remote ON’ on the
display, and “Communicator OFF” when logged off.
All commands should be followed by a carriage return.
The unit will respond either OK (or a value) if the command is accepted, or
NO if it is not.
To log on, send the command
/ACCESS:pppp where pppp is the passcode (P922).
To log off, send the command
/ACCESS:OFF
