DIP SWITCH SETTINGS
As shown in “Figure 2” on page 8, a set of eight dip switches can found on the lower left hand side of the controller.
These dip switches are used to set certain modes in the controller as described below. Changes to the dip switch
settings will only be applied when the controller is powered up or if you press the “Reset Switch” located on the
lower left hand side of the controller.
DEF/RUN DIP SWITCH
Set the dip switch to the off (Run) position for normal operation. If you wish to reset the controller to its
default settings, set the dip switch to the on (Def) position, then power up the controller or press the
“Reset Switch” on the lower left hand side of the controller. Default setting is off (Run).
9.6K/19.2K DIP SWITCH
Select the appropriate communications baud rate between the access control server and the network of
controllers. Set the dip switch to the on position for 9.6K or set the dip switch to the off position for 19.2K.
Default setting is off (19.2K). Verify that the CA-A360 Converter has also been set accordingly.
CONTROLLER ADDRESS ASSIGNMENT
Each site can manage up to 256 controllers. The 256 controllers are divided into four controller loops of up
to 64 controllers each. Using “Table 1” on page 10, set the dip switches to the desired controller address.
Each of these loops is assigned to a specific COM port. Controllers connected to the selected COM port
will be assigned to a specific address. The access control server (Centaur Software) will recognize these
dip switch settings. For more detailed information, please refer to the Centaur Software Manual.
CT-V900 CONTROLLER
9
12V/24V (LOCK #2)
Selects the output voltage of the “LK2+” terminal when the Lock#2 relay is active (default = 12V). When the
jumper is on pins 1 & 2 the output will be 12V. If the jumper is on pins 2 & 3 the output will be 24V.
HIGH/LOW (NETWORK IMPEDANCE)
Select the impedance of the RS-485 network (default = high). Set both jumpers to high when running
normally. When running the Centaur Lite edition and connecting directly to the 9-pin serial port, you must
set both jumpers to low.
EOL (E-BUS NETWORK)
Places the EOL termination of the controller’s E-bus network in circuit (default = on). If the controller is at
the end of the E-Bus network, the jumper should be on. If the controller is in the middle of the E-Bus
network, the jumper must be off. Please refer to Figure 4.
HIGH/LOW (E-BUS IMPEDANCE)
Select the impedance of the E-bus for the RS-485 (default: low). Set to low when running normally. Set to
high when running special E-Bus devices.
