How to use the LS-V5000 data radio module

LS-V5000 provides RS-232, RS-485 or TTL level interface port for direct connection with PC, RS485 devices, micro-controller and other UART equipment.

Power supply

LS-V5000 works in supply voltage 12V DC. By using better ripple factor, LS-V5000 transceivers can also share power supply with other equipments. If possible, a voltage-stabilizing chip with 12V voltage is more recommended as the only power supply than switch power supply. But if only switch power supply available, the jam by switch pulse to the transceiver should be avoided. In addition, the reliable grounding must be used if there is other devices in this system. In case of failing to connect with the ground, it can form its own grounding but must be absolutely separated from the municipal electric supply.
