RS232 to RS485 good for 5+PTZ  2400bps up to 300meters

Description

Access BCILDV RS1 (RS232/RS485 converter)

Introduction

Access BCILDV RS1 converter can convert the Transfer Data (TD) and Receive Data (RD) of RS-232C serial port to 2 wire half-duplex RS-485 signal. It's the best choice for long distance control devices and point to multi-point bus communications. This interface converter can work without power supply. It can "steal" power from TD signal, RTS signal of RS-485 port or DTR data terminator. It also has a plus function called Automatic Send Data Line Control, this is means that it doesn't need change the hardware configuration or install software. Perfectly surge protection ensures your RS-485 network security.
