CHAPTER 5
Remote Site Upload/Download
The 411UD digital communicator may be programmed off site via the public switched telephone network. Any per-
sonal computer with Windows
®
3.1 or greater or Windows
®
95, with a 1200 Baud Hayes compatible modem and
Upload/Download software P/N PK-411, may serve as a Service Terminal. For details on the remote site upload/
download software package, refer to the PK-411 Manual. The Upload/Download software allows the following:
• Download of the entire program
• Upload of the entire program
• Upload current status, system voltages or time
• Real-time upload, either continuous or 'snapshot' (one time) of current status or system voltages
• Download new time
CAUTION: Changes to program entries occur as a result of the downloading process. After successful down-
loading, make certain to perform the following steps:
1.
Manually view programmed entries and compare to intended program data.
2.
Test all affected system operations.
3.
Immediately correct any problems found.
5.1
General
Any time that the digital communicator is contacted, a secret code (factory default 0000) is verified between the dig-
ital communicator and the Service Terminal. Changing the Secret Code may only be accomplished at the Service
Terminal and subsequently loaded into the control panel. Future upload or download requests cause verification of
the Secret Code by the communicator before processing of data is allowed. If the Secret Code is not verified, the
communicator will terminate the request immediately.
When the 411UD is communicating with the Service Terminal, the communicator's green Modem LED and one of
the red Phone Line active LEDs will remain on steady. Upon termination of communication, the green Modem LED
will turn off and the red Phone Line active LED will turn off.
In order to contact the communicator, the following must be true:
The digital communicator may be in any mode of operation including Normal, Program, Real Time
Clock, Troubleshoot or Lamp Test. Downloading is not possible if the communicator is active during
Central Station communications or while testing the phone lines while in Troubleshoot Mode.
There cannot be any active communications ongoing with a Central Station receiver.
All active events must be successfully 'kissed-off' by the Central Station(s). The digital communicator
must be in a standby state with no new information waiting to be transmitted to a Central Station.
Two basic communication mechanisms are supported as follows:
• Contact with callback - The Service Terminal calls the digital communicator. The communicator answers the
call, confirms the calling party then hangs-up. The Service Terminal then waits for a callback from the com-
municator. After the digital communicator calls the Central Station and successfully reports that a request has
been received, the communicator calls the Service Terminal back. Upon secret code verification, data trans-
fers occur. When the data transfers are completed and the Service Terminal disconnects from the communica-
tor, the digital communicator calls the Central Station back to confirm either successful or unsuccessful
results.
• Contact with callback disabled - The Service Terminal calls the communicator. No hang-up sequence occurs.
Data transfers proceed.
Note that Callback enable/disable is controlled by the master user at the Service Terminal on a per call basis.
