Perle IOLAN SDS4 GR Secure Device Server 4-port 10/100/1000 RJ45 RS232/422/485

SKU CH-M8AQ-6V5AF

Connects four serial devices over Gigabit Ethernet with RJ45 ports supporting RS232, RS422 and RS485

  • Secure remote access over Gigabit Ethernet
  • Four serial ports support RS-232, RS-422 and RS-485
  • 10/100/1000 RJ-45 network interface
  • Industrial-grade security for critical infrastructure
  • Compact device server simplifies serial-to-Ethernet integration

Secure Device Server for Serial Integration

The Perle IOLAN SDS4 GR connects up to four RS-232, RS-422 or RS-485 serial devices to a 10/100/1000 Ethernet network. It suits industrial automation, building management or remote monitoring sites that need serial equipment accessible over IP without a local PC.

Gigabit Ethernet and Serial Rate Limits

The single RJ45 uplink auto-negotiates at 10, 100 or 1000 Mbps, so total throughput cannot exceed the negotiated line rate. Each serial port supports standard signalling up to the electrical limits of the RS-232, RS-422 and RS-485 interfaces, with no onboard buffering beyond the firmware queues.

DIN-Rail Mounting and Common Pitfalls

The unit clips onto a standard DIN rail and draws power from an external supply, so installers must verify voltage and polarity before wiring. Mis-matched serial parameters such as baud rate, parity or flow control are the usual cause of dropped data, and the RJ45 pin-out must match the chosen RS-232, RS-422 or RS-485 mode.

Questions about this item

Should I pick the four-port RJ45 model for my serial devices?

Yes, the unit provides four RJ45 ports that each support RS232, RS422 and RS485, so one device server covers all four connections.

What does the 10/100/1000 Ethernet rating mean when the server is installed?

The RJ45 network port auto-negotiates at 10 Mbps, 100 Mbps or 1000 Mbps, matching the speed of the switch or router it is plugged into.

Which serial interface standards are actually supported on the RJ45 ports?

Each port handles RS232, RS422 and RS485 signalling, letting you connect a mix of serial equipment without extra converters.
