*** DISCONTINUED *** This server is discontinued
A lot of automation equipment like PLCs, barcode scanners, digital signage, security access and CNC controllers still use RS-232, RS-422 and RS-485 serial communication. To connect this equipment to your network, you need a serial device server like Antaira’s STE-708A. A serial device server converts bi-directional serial streams to Ethernet TCP/IP packets and allows serial devices to communicate with an industrial network.
The STE-708A is a serial device server which converts up to 8 ports of RS-232 or RS-422/485 to Ethernet. With dual LAN ports, the system may be configured for daisy chaining, network redundancy or a ring topology. To meet industrial and factory floor applications, it is industrial rated and offers a wide operating temperature. High EMC protection and 2.5KV optical isolation is available in the RS-422/485 model. The STE-708A features:
