5.0 Communication
The communication section handles three different, but related, topics:
• Communication between EntraGuard Silver controller and tenants
• Communication between the master EntraGuard Silver controller and the host computer for programming
• Communication between networked EntraGuard Silver/PXL-500/510 controllers
NOTE: Keri Systems recommends performing a bench test on each unit prior to installation to rule out any phone line
problems.
5.1 Between EntraGuard Silver Unit and Tenants
The telephone communication is done via a copper phone line to TB-15. Connect the TIP line to either Pin 1 or Pin 2 then
connect the Ring line to the other Pin.
There are three ways of connecting the phone line for communication between the EntraGuard Silver unit and the tenants.
5.1.1 Single Phone Line for a Single EntraGuard Silver Unit
For a single EntraGuard Silver unit, connect the phone line to TB-15 on the EntraGuard Silver board (see Figure 2 on
page 2).
5.1.2 Individual Phone Lines for each EntraGuard Silver Unit on a Network
The set up for individual phone lines for each EntraGuard unit is the same as for a single phone line for a single
EntraGuard Silver controller. Each phone line is connected to TB-15 on each EntraGuard Silver board.
5.1.3 Shared Phone Line for Multiple EntraGuard Silver Units on a Network
A single phone line may be shared for communication between multiple EntraGuard Silver units and tenants. The phone
line is plugged into TB-15 on the master EntraGuard Silver unit with the phone line then going out of the TB-15 phone
plug to the next unit’s TB-15 and so on to all the networked EntraGuard units.
NOTE: Sharing a phone line for multiple EntraGuard units is limited to a maximum of 6 units per phone line.
5.2 Between EntraGuard Network and Host Computer
A communication link between the EntraGuard network and the host computer is provided via one of two ways.
• using the phone line connected to TB-15
• using the RS-232 serial port
NOTE: In order for monitor mode to work, the RS-232 serial port method must be used (see Section 5.2.1 on page 7).
NOTE: If a PXL controller is connected to the EntraGuard, it may be used as the master controller for communication
which will free up the phone line. For further information on communication alternatives, see either the PXL-500/PXL-
510 Quick Start Guide (P/N 01918-001) or the PXL-500G-1 Quick Start Guide (P/N 01532-001).
5.2.1 RS-232 Serial Port
Using the RS-232 serial port for communication between the EntraGuard unit and the host computer may be done one of
two ways:
• by direct connect (maximum of 50 feet)
• through an approved
1
external modem.
For either of these options, the INT_MODEM J11 jumper should not have a jumper across it. Verify there is no jumper set
across J11 (see Figure 2 on page 2) when using the RS-232 serial port for communication.
1. For a list of approved external modems, see the Recommended Peripherals List (P/N 01924-001).
