4-Port RS-232 Ethernet Adapter

The Brainboxes ES-701 connects four RS-232 serial devices to an Ethernet network. Each port uses a 9-pin DB-9 male connector for direct cable attachment. The IP-30 rated enclosure is wall-mountable and DIN rail mountable. Simple operation is provided for each and every operating system.

Who this suits and who it does not

Industrial engineers integrating legacy PLCs, meters or barcode scanners into modern LAN infrastructure will find the four ports and rugged housing fit the task. Installers needing Power over Ethernet or wireless connectivity should look at alternative solutions. Buyers who require more than four serial ports must choose a different adapter.

Deciding specification — port count and connector

Four 9-pin DB-9 male RS-232 ports define whether this unit matches the device count and cabling you have. The adapter measures 34 mm high, 215 mm wide and 132 mm deep, weighing 678 g. TAA compliance is confirmed for regulated procurement.

Questions about this item

How is the ES-701 mounted and which step is often missed?

The adapter is wall-mountable and DIN rail mountable; the step often missed is securing both the wall brackets and the DIN rail clip for a stable fit.

What maintenance or replacement will the ES-701 need over time?

The IP-30 rated enclosure protects against solid objects; no internal user-serviceable parts exist, so maintenance is limited to checking cable connections and LED status indicators.

What physical limit appears first when the ES-701 runs continuously in a warm cabinet?

The IP-30 enclosure offers no active cooling, so the operating temperature limit of the internal components is reached before any port throughput ceiling.
