Industrial 8-Port RS-232/422/485 Serial Device Server, AC Input, 1U Rack Mount Size

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:

  • Select 8 ports RS-232 or RS-422/485 model
  • Dual 10/100Mbps Ethernet ports
  • 1U 19” rack mount metal enclosure
  • Optical isolation for the RS-422/485 model
  • Serial data throughput rate of 50 to 921.6 Kbps
  • Supports virtual COM, TCP/UDP server/client and tunneling mode
  • Built-in web console and windows utilities
  • Front panel console port, LED status display and LED configuration buttons
  • 100 to 240V AC Power Input with choice of US plug or EU plug
  • Wide operating temperature range of -20° to 70°C
  • 5 year warranty
  • Included accessories: RJ45 to DB9 male serial cable, AC power cord, product CD and hardware installation guide, 19" rack mount kit and rubber feet for benchtop use
