Central Station Acknowledge
There is an option whereby the communicator will report to one or both Central Stations that a request for upload-
ing or downloading has been received prior to processing the call. This is called the 'callback' option. If the Cen-
tral Station(s) does not acknowledge receipt of this request, uploading or downloading is prohibited. If
acknowledged by the Central Station(s), another message is transmitted informing the Central Station(s) that:
• downloading was successful
• uploading was successful
• uploading/downloading was not successful
Data Protection/Integrity
Programming data is completely verified for accuracy prior to reprogramming of the 411UDAC EEPROM.
Incomplete or corrupted data packets are ignored or retried.
5.2
Downloading to the Communicator
Before initiating the download procedure, make certain that the communicator is in the standby state.
Once an incoming call is accepted/answered by the communicator, the 411UDAC will:
1.
Establish basic modem connection
2.
Verify secret code
3.
Verify callback vs. no callback request from the Service Terminal. If callback is requested, perform steps 4
through 10; if no callback is requested, perform steps 9 and 10 only
4.
Verify product type
5.
Identify the Service Terminal location
6.
Hang-up/disconnect call
7.
Call the Central Station(s) and transmit a request for upload/download message (if programmed to do so). If
this message is accepted, the communicator will proceed to the next step
8.
Return call to the Service Terminal
9.
Verify secret code
10.
Verify Product type
11.
Begin downloading
12.
Upon completion of download, call the Central Station(s) back and report a successful download or failed
upload/download status (if programmed to do so).
5.3
Uploading From the Communicator
Items that may be uploaded from the communicator to a Service Terminal are:
• All or portions of programmed data plus the real time clock
• Troubleshoot system voltages in real-time or as a 'snapshot'
• Current system status in real-time continuous or as a 'snapshot'
Uploading is possible at any time provided the following conditions are true:
