8 1892 1211 - SR500 Receiver Operating Instructions - 2.10 / May 2006
Channel Selection Mode (F7 and F4)
Having programmed frequencies into the channels, you can specify which channel to use
(channels 0-127) or that the channel will be selected by parallel logic levels (channels 0-7
only).
The unit defaults to serial channel selection whenever it has serial communications, which
includes whenever the STSRn00.exe software communicates with it.
To select serial control, and a channel from 0-127 (which will be used until further
commands are received), press F7. Type the new serial channel number and press
<enter>
v The channel is displayed in ‘Serial channel selected’.
v The channel command is sent to the unit immediately and becomes
operative.
To enable parallel channel selection mode press F4 (Parallel channel mode).
v ‘Parallel channel selected’ is displayed. The channel number is unknown,
because it depends on the logic levels applied to three inputs as described
on page 4.
Parallel channel mode select (F4) must be the last action before disconnecting the unit:
any further serial communication will reset it to serial mode.
Completing Programming
This completes programming and the unit may be disconnected. It is not necessary to
switch off power or stop the program first.
Programming Further Units
Further units may be programmed by disconnecting one unit and connecting the next,
which may be done without switching the power off.
v If you want to use the channel frequency settings from the previous unit,
either as they are or as a basis for editing, do not stop the program, because
it does not save settings between sessions.
v Note the caution on page 6 regarding mixed unit types
Proceed as above, using F6 to program the unit when all the channel parameters are
correct, and selecting a channel number (F7) or parallel selection (F4) before
disconnecting the unit.
