یک فرستنده و گیرنده بی سیم قدرتمند دیجیتال با قیمتی مناسب می باشد که به عنوان اتتقال داده های بی سیم در مسافتهای کوتاه مورد استفاده قرار می گیرد.

مبدل سریال به وایرلس pl863 با اندازه های کوچک ، وزن و توان مصرفی کم و ثبات خوب در سیستم های دو طرفه انتقال تست و کنترل قابل اطمینان است.

Application fields

PL-863 wireless, 433 MHz free band, digital transmission module offers standard RS-232, RS-485 and UART/TTL level interfaces for direct connection with computers, use’s RS-485 equipments, SCM or other UART parts.
PL-863 has adopted half duplex communication channel most suitable for point to multi-point communication mode. The primary station takes full control of communication harmony, and adopts data frames with address codes for data or command transmitting. The secondary station shall fully receive them and select response by comparing address codes; all the work shall be fulfilled by upper layer protocols, which shall ensure that only one wireless module in the communication network is in the transmitting state in any instant to avoid mutual interference. Therefore, the transmission channel built by PL-863 is transparent to the user.
PL-863 can also be applied to point to point communication, making it easier and smoothly upgrade wire (RS232/485/TTL) transmission mode in original system.
