Serial port provides 1500W surge protection and 15kV electrostatic protection

RS-485/422 port provides optional connection ways, including RJ45, DB9M and 5-pin terminal blocks

Introduction

MODEL485P is a RS-232 to RS-485/422 interface converter that can achieve bidirectional conversion between RS-232 and RS-485/422. It provides 1 RS-232 serial port and 1 RS-485/422 serial port. The RS-485/422 supports serial port self-adaption technology that can identify RS-485/422 serial port automatically without the need of setting the switch. Serial ports are equipped with 1500W surge protection, 15kV electrostatic protection and 2500V photoelectric isolation protection, which can effectively avoid surge and lightning strike. The device also adopts wall mounting, which can meet the requirements of different scenes.

Hardware adopts fanless, low power consumption, wide temperature and voltage design. It can be wildly used in indoor and outdoor system like attendance, entrance guard, cloud platform control, food selling and parking lot, etc.
