You can use this command—which causes the Professor to switch back to the
station you had previously selected before selecting the station you’re currently
connected to—as a convenient method of switching back and forth between two
stations/CPUs. (This is especially useful when you have many CPUs, so that you
can avoid entering the multi-digit station numbers.) To switch to the previously
selected station, press and release the left [Ctrl] key, then press the [Backspace]
key. This will give you view-only access, as if you had entered a View Station
command (see
Section 4.3.1
); to gain shared or sole keyboard and mouse control,
you’ll need to issue a Share Station or Control Station command (see
Section 4.3.2
or
4.3.3
respectively).

To start scanning (switching from station to station in a continuous rotation) from
the keyboard, press and release the left [Ctrl] key, then press [S]. The ServSwitch
Professor will begin scanning sequentially from your currently selected station. If
the currently selected station is within the range defined by the current Minimum
Scan Station and Maximum Scan Station settings (see
Section 4.3.16
.), the
Professor will scan through the higher-numbered stations until it reaches the
Maximum Scan Station, then begin again at the Minimum Scan Station. If the
currently selected station is outside that range, the Professor will switch to the
Minimum Scan Station first,
then
begin scanning.
As it scans, the Professor delays 1 to 15 seconds at each station. (This “Scan-Delay
Time” is user-selectable; see
Section 4.3.15
.) To stop scanning, press and release
[Ctrl], then press [X]; you can also stop a scan by entering a station-selection
command. (Remember that ServSwitch Professor letter commands are not case-
sensitive: You can enter upper- or lower-case letters.)
If you want the Professor to begin scanning immediately at power-up, issue the
Keep Settings ([Ctrl][K]) command (see the next section) while the unit is
scanning. In order to maintain this setting, however, you’ll need to be very careful,
because power-up scanning is just as easily turned off by ending a scan with
[Ctrl][X] and then issuing a Keep Settings command. This means that if you end a
scan with [Ctrl][X], then change a configuration setting and issue Keep Settings
at
any time afterward before you scan again
, power-on scanning will be turned off. To
maintain power-on-scanning as the ServSwitch Professor’s default state, you need
to do one of two things:
•
Always
end your scans by selecting a specific station with commands such as
View Station or Select Station.
•
Never
issue a Keep Settings command except while the Professor is scanning.
