1.4.5 Terminal Matched Resistance Setup
The connection mode of device terminal 120Ω resistance is equipped on the power board. There
are two connection modes which are shown in Figure 1-7.
Figure 1-7
The factory default connection mode is shown in Figure1-8; the jumper (connection board) is
plugged into pin2 and pin 3, which means 120Ω resistance is not connected to the device.
Figure 1-8
If you want to connect the 120Ω resistance, you have to pull the jumper out of pin 2 and pin 3,
and connect to pin 1 and pin 2, then 120Ω resistance is connected to the circuit, see Figure 1-9.

1.5 Reset and SD Card Installation (network speed dome)
You can see there is a RESET button and Micro-SD card slot on the PCB after you open the dial
switch cover. See Figure 1-10. Reset button is used to reset network system. Micro-SD card is
used to save the data.
