  • IP30 polyamide enclosure protects in industrial settings
  • Single serial port handles RS232, RS422 and RS485

Industrial serial device server

The Brainboxes ES-511 connects one RS232, RS422 or RS485 serial device to a 10/100 Base TX Ethernet network. Auto-gating circuitry manages RS485 half-duplex flow control without software intervention. Configuration is handled through a web interface and an RFC2217-compliant socket. The IP-30 rated polyamide enclosure is non-conducting and built for industrial environments.

Engineers integrating legacy serial kit

This unit suits engineers who need to place a single serial instrument on an IP network for remote monitoring or control. It is not for installers who require multiple serial ports on one device, nor for sites that need gigabit Ethernet throughput or Power over Ethernet. Buyers needing wireless connectivity or DIN-rail mounting hardware not included here should look elsewhere.

One serial port with triple protocol support

The defining specification is the single port that operates as RS232, RS422 or RS485 selectable in software. This flexibility lets the same hardware replace several dedicated converters while the auto-gating feature removes the usual RS485 timing headaches.

Questions about this item

What Ethernet cable and power source are needed to connect the ES-511 to the network?

The ES-511 has a 10/100 Base TX Ethernet port; use a standard Cat5 or better patch cable and supply the rated DC voltage for the terminal block.

Will my existing RS-232, RS-422 or RS-485 serial equipment work with the ES-511 without changes?

The port supports RS232, RS422 and RS485 with auto gating for half-duplex flow control, so legacy serial devices can connect directly.

How can I verify the ES-511 is operating correctly after installation?

Open the web configuration page or an RFC2217 client; the interface shows link status, serial port settings and data counters confirming operation.
