EXC/RTX19 - USER & MAINTENANCE MANUAL - rev.1.5 - 05/16

     Page    39

   SETUP CONTROL
   LOCAL & REMOTE

  REMOTELY LOCKED
  PRESET TO LOCAL!

 FREQ. 2470.175 MHz
F= -55dBm T=+ 1.2kHz

RECEIVER SETUP MENU

Field #21: Local/Remote control setup

The apparatus may be controlled either locally from the front panel or remotely from the I/O

lines and RS232 serial port. It is possible to permit concurrently control as default shown (remote
I/O lines may be prevalent in case of any function disable) or only local or by remote. So the
highlighted line may be changed in:

     LOCAL ONLY

or

     REMOTE ONLY

In case the apparatus is remotely locked, any temptative to access to setup menu will show the

following message:

Pushing twice "Enter" on the control jog will select the "SETUP CONTROL" menu and highlight the

upper field ("REMOTELY LOCKED") permitting to change it to "LOCAL & REMOTE" or "LOCAL
ONLY" if  required.

Field #22: Frequency setup

Here it is possible to preset the received frequency in a similar manner as in the transmitters.

In the receiver the frequency is changed in real time with editing, whenever possible.

The bottom line shows the associated received field and center tuning. Bear in mind that very

often major frequency changes requires several seconds to be effective and during this time the
infomation on the bottom line is meaningless.
