Programmable I/O line. This line could be connected to the lighting
control circuit at the site via the system interface connector.
Example Two
The customer also wants an acknowledgement sent back to confirm that the
command to turn on the lights was received.
At first the solution would appear to be to enable Selcall auto
acknowledgments. However this would not work, because the base station
has separate receiver and transmitter modules. The receiver module will
decode the selcall and enable the I/O line, but has no method of informing
the transmitter to send back an acknowledgment. In fact the receiver
module would attempt to transmit the acknowledgment itself, but would be
inhibited by other mandatory settings.
7.8.6 Function Keys
The base station also has four user-defined function keys on the user
interface, and programmable digital input and output lines on the system
connector.
The tables below list the options that can be assigned to the function keys
and the digital input and output lines. The grey cells can be programmed
but are not recommended (see
“Recommended Settings” on page 112 ).
