Perle STS4-D portable audio

SKU CH-ZY9J-JNCRJ MPN STS4-D

A four-port RS-232 terminal server with Fast Ethernet and TrueSerial technology for protocol integrity

  • TypeTerminal Server
  • Authentic serial connections over Ethernet backed by TrueSerial technology
  • Four RS232 ports connect multiple legacy devices to a single network drop
  • Fast Ethernet 10/100Base-TX provides reliable wired throughput
  • RoHS and WEEE compliant for environmentally responsible deployment
  • Compact desktop or wall-mount form factor fits tight equipment spaces

Four-port RS232 terminal server

The Perle IOLAN STS4-D is a desktop or wall-mountable terminal server that converts four serial RS232 ports to a single 10/100Base-TX Fast Ethernet link. TrueSerial technology preserves device protocol integrity across the network. It is built for engineers and project managers who need a cost-effective way to connect legacy serial equipment to modern LAN infrastructure. RoHS and WEEE compliance confirms environmentally responsible manufacturing.

Desktop or wall mounting with one Ethernet uplink

The unit measures 1.1 inches high, 4.4 inches wide and 3.2 inches deep, fitting on a bench, a shelf or a DIN-rail bracket. A single RJ-45 port handles the 10/100Base-TX uplink over twisted-pair cabling, so no additional network interfaces are required. Power over Ethernet support is available on compatible models, which can eliminate the need for a local power supply at the device location. The compact form factor frees rack space for other gear.

Suited for small serial-to-Ethernet deployments

This model serves sites that need exactly four RS232 connections bridged to Ethernet without the cost or complexity of larger port-count servers. Buyers who need more than four serial ports, fibre uplink options or gigabit Ethernet speeds should evaluate other products in the range. Operations that require wireless connectivity or integrated switching will also need a different solution.

Questions about this item

How many serial devices can the four RS-232 ports connect at once?

The unit provides four serial ports, each supporting one RS-232 device for a total of four simultaneous connections.

What is the power draw of the 10/100Base-TX Ethernet link during continuous operation?

The Fast Ethernet port runs on standard 10/100Base-TX twisted pair without PoE, so power consumption stays low and the desktop chassis remains cool.

Does the desktop enclosure include mounting brackets for a wall or DIN rail?

The specifications list both desktop and wall-mountable form factors, so brackets or keyhole slots are provided for wall installation.
