2. Press the pound key (#) on each keypad. A serial number should be displayed in the EntraPass message desktop. Look for
the type of module and the controller to which it is connected.
3. From the EntraPass controller definition window, select the functionality of the KT3-LCD and enter the serial number in the
appropriate field (refer to
Chapter 4, Defining Devices
of the
EntraPass Reference Manual
for more details).
Troubleshooting Communication Problems
Default Initialization
The KT-315 default initialization is done at Kantech. The following steps should only be followed if:
a You are using a KT-315 from another site and there is no communication;
b The KT-315 was communicating via the RS-232 port and you installed a VC-485 to
communicate via the RS-485 port;
c You were using the KT-315 at a local site and now want to configure it for remote operation.
How to Use the Default Initialization (Hard Reset)
1. Disconnect both transformer and battery.
2. Remove all connection to DOOR1 and RL1 terminals.
3. Place a jumper between the DOOR1 and RL1 terminals.
4. Apply AC power to the transformer. The VITAL LED should flash 4 times. This means that the
controller is in the initialization mode.
5. Remove jumper.
6. When the controller is connected to the computer, the VITAL LED should flash 3 times, alternately.
7. Reconnect the battery.
VITAL LED status indications
Communication status and other vital controller parameters can be obtained from VITAL LED
pulsations. This information is particularly useful when connecting the controller to the rest of the
access control system. Consult the KT-315 Controller Wiring Diagram on page 22 to locate the VITAL
LED. The following table lists all conditions along with a brief description
