Multi-COM Ports with Programmable Device Servers

There are generally a lot of general purpose devices to integrate with the central system in factories and offices. A card reader with an RS-232 interface is set outside of the door and far away from the central system. A device server enables the card reader to communicate with the central system by converting the serial RS-232 signal to Ethernet protocol. A PLC controlling lights, buttons and air conditioning call for multi-COM port connections. Through Ethernet, we can extend transmission distances. PDS also features programmability. Rooms can light up automatically just as someone is about to eneter. PDS and DS are great serial to Ethernet solutions. DS-712 is equipped with RS-485 and ethernet ports. PDS-742-IP67 is waterproof and dustproof. PDS-782-258 is designed for easy wiring. PDS-775 is equipped with 7 RS-485 COM ports at one time.
