Connecting a KTD-405 keypad and dome
camera to the DVR
Use the input/output box that is supplied with the keypad to connect the KTD-405
keypad to the DVR. See Appendix D “KTD-405 keypad” on page 127 for more
information on wiring and using the KTD-405 keypad.
As the KTD-405 keypad uses full duplex data communication, you cannot
connect the both keypad and a dome camera directly to the DVR 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 DVR. See
Figure 5 as well as Table 4 and Table 5 below.
Note: These connections only work with UTC PTZ protocols (see Appendix B on
page 123). If you are using another manufacturer’s PTZ protocol, it is not
possible to connect both a keypad and dome camera to the DVR.
