Connecting a KTD-405 keypad and dome camera
to the recorder
Use the input/output box that is supplied with the keypad to connect the KTD-405 keypad to the
recorder.
As the KTD-405 keypad uses full duplex data communication, you cannot connect the both
keypad and a dome camera directly to the recorder from the RS-485 port as this could cause
problems on the bus. If both devices are required, it is recommended that you use the keypad’s
RS-422 connection to connect the dome camera and the keypad’s RS-485 connection to
connect the recorder. See Figure 5 as well as Table 4 and Table 5 below.
Note: These connections only work with UTC PTZ protocols (see Appendix B “PTZ protocols”
on page 134). If you are using another manufacturer’s PTZ protocol, it is not possible to
connect both a keypad and dome camera to the recorder.
