•
The SC9000 transmits a message to the Radio Communicator that contains the assigned Radio
Communicator number and Framer parameters to be programmed in the CPU of the Radio Communicator.
•
When the Radio Communicator CPU is programmed with the Radio Communicator number and the Framer
parameters, the Radio Communicator will perform a system reset and then send in a “restart” message to
the SC9000 computer.
•
The SC9000 then downloads the remaining program parameters from the Radio Communicator account to
the Radio Communicator in the field.
•
Once the download procedure is complete, the Radio Communicator transmits an ACK to the SC9000
Receiver.
•
This ACK message gives the SC9000 confirmation that the Radio Communicator download is complete and
the “program complete” message is displayed on the screen of the SC9000.
The Radio Communicator download is complete. The Radio Communicator is now on-line and operational for a radio
communications link between the remote client location and the central station SAFECOM receiver.
3.3. Removing a Radio Communicator Account from the SC9000
When a customer account needs to be permanently closed, it may be removed (deleted) from the SC9000 Receiver. The
following procedures will:
•
Remove the entire account for a specific customer in the SC9000 computer.
•
Terminate radio communications with this specific Radio Communicator.
•
Remove the data previously downloaded into the SAFECOM Radio Communicator, and make it ready to install at
another site in the future.
3.3.1. To Remove a Radio Communicator Account from the SC9000 Receiver
1. Press the F1=SELECT option from the “System Status Menu” command window. The “Select a Remote” menu will
then be displayed.
2. Enter the Radio Communicator number of the Radio Communicator to be removed, and press ENTER.
3. The screen will display the message “Polling remote XXX depress ALT-X to fail” in the upper right hand corner of the
screen.
4. The Radio Communicator will transmit its Status to the SC9000, and it will be displayed on the screen.
5. Then press the F2=SETUP option from the command window. The Radio Communicator’s account setup menu #1
will be displayed.
6. Then press the F2=DELETE option from the command window. The message “Delete all parameters for this
remote?” will be displayed in the operator prompt area.
7. Press the “ Y “ key to answer yes. The Radio Communicator’s Account Setup menu #1 will remain displayed.
However, all data including CPU S/N, PID, & Framer will be deleted. The data fields will then be displayed as all
zeroes (000000000).
8. Select the ESC=EXIT option from the command window. The message “Save changes before exit? (depress ESC to
continue editing)” will be displayed on the screen.
9. Press the “ Y “ key to answer yes.
10. The SC9000 will display the message “DEACTIVATED” in the record of events on the left hand side of the screen.
The SC9000 then transmits an initialize message to the Radio Communicator to erase all previously downloaded
data. The message “This remote does not exist.” will be displayed in the operator window on the right hand side of
the screen.
11. The Radio Communicator will send an ACK message to the SC9000 and the message “INACTIVE XXXXXXXXX”
(XXXXXXXXX is the CPU S/N of the recently deactivated Radio Communicator). This message notifies the operator
that the Radio Communicator has its downloaded program erased and can now be powered down and installed at a
new customer site when necessary.
12. The Radio Communicator (program now erased) will transmit the startup message for 90 seconds, just like a new
SAFECOM radio out of the box.
13. The Radio Communicator is now inactive and all associated data about the customer has been removed from the
Radio Communicator and the SAFECOM SC9000 computer.
NOTE: The number that was assigned to the recently deactivated Radio Communicator is now available to be re-
assigned to a new or different Radio Communicator.
