Description
Ethernet to Serial device server providing access to eight RS422/485 serial ports. Data transfer rates up to 230,400 baud, coupled with 1Mbit/s
line drivers deliver uncompromising performance. Our ES range provides simple instant networked serial ports. RS485 - 2 wire half duplex
configuration with autogating provides trouble free data transmission due to automatic control of data direction. A web interface allows secure
configuration and control of the serial ports over a local network or the internet using any browser. For Windows our in-house designed (32 bit
and 64 bit) driver gives you local COM ports, retaining existing software applications and allowing you to connect across your network to remote
devices just as if they were attached locally. Serial Port Tunneling (individually configurable) allows serial cable replacement over any distance, no
software required. You can access the device via TCP/IP sockets from any networked device like an Android tablet, PC or phone. On Windows OS
TCP/IP sockets are handled by the Winsock API, this will differ on other OSs.
Windows Users - Our software drivers gives you local COM ports, allowing you to retain your existing software applications and connect to your
devices over the network. COM Port can be assigned from COM1 to COM255 and the Brainboxes Ethernet to serial device remembers your COM
Port assignment on reboots.
Web Interface Users (Linux/Apple OS/Android) - Alternatively access the device via TCP/IP socket from any networked device. Configure options
via web interface.
Extend your reach! Remote serial devices with local control. With Brainboxes industry renowned Lifetime Warranty and Lifetime Support!

RS422 Standard: RS422 allows one transmitter and up to 10 receivers with data transmitter rates up to 10
megabits per second for distances up to 40 feet and up to 100 Kilobits per second for distances up to 4,000
feet (1219 metres).
To achieve good long distance noise immunity, 2 wires are used to carry each signal, configured as a twisted
pair of cables. The TXD pair and RXD pair are used to carry the data whilst the RTS pair and CTS pair lines are
used for handshaking. Thus 2 twisted pairs are used without handshaking and 4 twisted pair cable is used with
handshaking both these schemes allow full duplex data communications.
RS485 Standard: RS485, based on the RS422 standard allows up to 32 driver/receivers pairs on a standard
load or 128 low load devices per port can be connected. Whilst only one of these should be transmitting data
at any time, the rest can all simultaneously listen to the data. Handshaking is performed by software protocol.
Two twisted pairs form a full duplex system.
Often only one twisted pair cable is used as the TXD and RXD lines are tied together; this is known as
half duplex mode. Brainboxes RS422/485 products implement a state of the art hardware autogating circuit
ensuring error free communications in half duplex configurations.
