2.2
Connecting to an EntraGuard Gold Controller
A short haul modem may be used with an EntraGuard Gold master controller however, due to
the size of the short haul modem, an extension cable must be made to allow the modem to be
located outside of the controller box so the box may close properly.
The DB-9 connector on the short haul modem and on the EntraGuard Gold controller are both
female. To make the short haul modem to controller connection two DB-9 male connectors are
required and a minimum of 3 conductor cable (length as needed). Set the switch on the short
haul modem to the DCE position by gently turning the switch completely counter-clockwise.
