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. See Appendix D “KTD-405 keypad” on page 133 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 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 on
page 130). If you are using another manufacturer’s PTZ protocol, it is not
possible to connect both a keypad and dome camera to the recorder.
