3.4.11 Link Integrity Checking
The generator has a built-in function that detects the loss of the
RS-232 serial link on the digital interface. This is called link integrity. If
the RS-232 link seems to have been broken, the generator will shut off
the RF power and not allow the RF to be turned back on until the link is
restored.
The generator always defaults at power-on with this function disabled.
To enable the function, a
[^W] must be sent from the host. Once the
host initiates this function, the generator will expect to see [^W] sent
from the host on a continuous basis. If another [^W] is not received
within one second of the last one sent, the generator will assume the
host is no longer connected and produce a link integrity error, thereby
shutting off the RF power.
If link integrity checking has been enabled by the host, you may later
disable it with the
LIT command.
Check for proper link integrity control in the following manner:
1. Turn the generators AC power ON via the main AC breaker
switch.
2. Turn the RF power on via the front panel.
3. Send a [^W] by pressing the W key while holding down the CTRL
key. Within one second, the RF power should go off because
another
[^W] was not sent.
4. Try to turn the RF power back on via the front panel. It should not
go on.
5. Enter the command RFV= . The generator should return a Link
Integrity fault.
6. Enter the command LIT . Again enter the RFV= command. The
generator should now show no faults, and you should be able to
turn RF power on via the front panel.
7. With the RF power on, send many [^W] s in succession. Make
sure you send at least one every second and ensure the RF
power stays on while you are sending the
[^W] s. Once you stop
sending the [^W] s, the RF should go off as it did before. Reset
the generator with the LIT command again.
