3.2 Radio Interface (Type SMA Connector Female) - RF Antenna
Figure 4: Antenna Connector for MLB-S-BGS2-BW
The connection of the antenna or other equipment must be decoupled from DC voltage.
For optimum RF performance, the MLiS Terminal has to be connected to an external RF antenna
matched to 50ohms including other connecting cables across the operating frequency bands. Please use
a SMA Male connection to the terminal.
Choose suitable types of low attenuation coaxial cables if possible. In general the RG174 or RG58 50
ohms types should be good for normal use. Avoid excessive cable length of > 10 metres.
＊
Compatible RF antennas (PCB patched or Monopole type) are available for order, please
refer to accessories document.
3.3 RJ45 Connector
The RJ45 Modular COM port is used to supply power to the terminal as well as provide serial data
communication. The terminal accepts voltage levels b5Vdc to +32Vdc. Do not exceed these
levels. The minimum requirement for the terminal to communicate with the application or DTE is through
using the following pins:

TxD: Where the Application sends data to MLiS Terminal

RxD: Where the Application receives data from MLiS Terminal
