4] ACCESS CONTROL SYSTEM INSTALLATION
You have two options for connectiong the CA-A360-USBRS to the computer. You can
connect one end of the 6 pin cable that comes with the CA-A360-USBRS module
to the connector on the module. The other end of the 6 pin cable should be connected
to the serial communications port on the computer using the appropriate adapter
(9 and 25 pin adapters provided). Or you can connect a USB wire (not provided) from the
CA-A360-USBRS to the computer.
Connect the A+, B- and GND terminals of the CA-A360-USBRS module to the A1+, B1- and
GND terminals of the first controller using shielded, 4 wire, stranded cable (refer to Figure
1). The +12V and GND terminals of the CA-A360-USBRS should be connected to the
+12V and GND terminals of the CT-V900-A controller (refer to Figure 1).

5] REPEATER MODULES INSTALLATION
Using the screw-in terminals, connect RX of the first CA-A360-USBRS repeater module
to TX of the 2nd module. Connect TX of the first module to RX of the 2nd module.
Ground terminal of the first module should be connected to GND on the 2nd module
(7.6m / 25ft maximum). Connect the A+, B- and GND terminals of each CA-A360-USBRS
module to the A1+, B1- and GND terminals of the appropriate controller using a shielded,
4 wire, stranded cable (refer to Figure 2). Power can be supplied by the model CT-V900-A
controllers or a separate power supply. When using a separate supply, connect the GND
terminal of the CA-A360-USBRS module to the negative terminal of the controller.
