CTV900A
2-Door Controller
INSTALLATION MANUAL
EOL (CONTROLLER NETWORK)
Places the EOL termination of the main controller network in circuit (default = o). Jumper should only be on
when the controller is the last controller in the network as demonstrated below.
12V/24V (LOCK #1 and LOCK #2)
The default output voltage of the “LK1+” or “LK2+” terminal when the lock relay is active is 12V.
See jumper settings table to set at 24V.
HIGH/LOW (NETWORK IMPEDANCE)
Select the impedance of the RS485 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 o. Please refer diagram below.
HIGH/LOW (E-BUS IMPEDANCE)
Select the impedance of the E-bus for the RS485 (default: low). Set to low when running normally. Set to
high when running special E-Bus devices.
