E{x}it
To select a menu item, press any key that is within braces {}. Simply pressing ENTER will
redisplay the current menu. If you do not press a key for 30 seconds, the RTU will
automatically exit the menus. You must press the space bar three times to re-access.
Prekey Time
This menu selection allows the user to change the delay between the time PTT is activated
and the time the MSK signaling begins. The default is 500 milliseconds and can range from 0
to 4 seconds in 100 millisecond increments.
For trunked operation, this is the delay from the time a channel-acquired signal is received on
the COR input until the data is sent. If there is no delay required (as should be with trunked
radio), set this to zero.
CAUTION
THE RTU CONTAINS A DATA COLLISION ALGORITHM. TO AVOID
MULTIPLE DATA COLLISIONS, SET THE PREKEY TIME OF EACH RTU
TO THE SAME VALUE!
