描述 Description

The PL2303GR is a low cost and high performance USB-to-RS485 Bridge Controller with built-in RS485 transceiver. The PL2303GR provides a convenient solution for connecting an RS-485 half-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL2303GR highly compatible drivers could simulate the traditional COM port on most operating systems allowing the existing applications based on COM port to easily migrate and be made USB ready.
The PL2303GR integrates a high baud rate RS-485 transceiver that meets the EIA/TIA-485 communications interface specifications. The RS-485 transceiver build in TVS protection for bus terminals of ±15kv contact discharge and ±18kv air-gap discharge. It provides the bipolar output to the transmitters, and makes the transmitters to deliver the RS-485 output voltage levels. Under normal operation, PL2303GR operates at very low power consumption with guaranteed data rate up to 10Mbps.
