4b. LRR Line Card mode is used when the
7810iR will communicate with a digital
receiver. Baud rate is set by the line card at
19.2 kb/s. Check the Fail to Manual
doughnut if this feature is required.
4c. 685 Automation mode is used when the
7810iR will communicate directly with
automation equipment. Touch Automation
Baud Rate and RX Line Number to configure
these parameters. Check the Fail to Manual

Any changes made to Automation will
automatically be saved.
5. To use Virtual Private Network (VPN), one
or more additional Central Station ID's, each
greater than the CS number programmed into
the 7810iR, must be assigned by AlarmNet.
The VPN doughnut must be checked as
shown.
The VPN feature is a means to increase the
number of accounts reporting to one 7810iR
and is functional in 685 Automation Mode
and LRR Line Card mode.
When an alarm message is received, the
7810iR's programmed CS number is
subtracted from the CS number of the
received message and is then added to the
programmed RX Line Number. The result is a
virtual line card number. The 7810iR reports
the alarm to the automation equipment using
the virtual line card number. The virtual line
card number is also displayed on the 7810iR.
For example, a 7810iR is programmed for 685
Automation Mode as CS ID 0089 and RX Line
Number 14. To use VPN, AlarmNet assigns
CS ID 008A.
When an alarm message is received for CS
008A, the 7810iR subtracts the programmed
CS number from the received CS number: 8A
- 89 = 1. The result is then added to the RX
Line Number: 1 + 14 = 15. The received
alarm message will be reported to automation
