HDCVI Speed Dome
It is to set the speed dome baud rate. 1 and 2 bit are used to set baud rate, 3 and 4 bit are used
to set HD/SD video mode. See Figure 2-6 for baud rate and mode; refer to Table 2-4 and Table
2-5 for baud rate and mode setup.

2.4 Terminal Matched Resistance Setup
The connection mode of device terminal 120
Ω resistance is equipped on the power board. There
are two connection modes which are shown in Figure 2-7.
120Ω
1-2
ON
2-3
OFF
Figure 2-7
The factory default connection mode is shown in Figure 2-8; the jumper (connection board) is
plugged into pin2 and pin 3, which
means 120Ω resistance is not connected to the device.
Figure 2-8
If you want to connect the 120
Ω
resistance, you have to pull the jumper out of pin 2 and pin 3,
and connect to pin 1 and pin 2, then 120
Ω
resistance is connected to the circuit, see Figure 2-9.
