• LEDs which show transmitting and receiving of data.
• Easily mountable
• Metal Housing
• Dimensions of 167× 99×29 mm³ (W×L×H) or 189×102×30 mm³ with DB9 connectors and ears.
• Virtual COM port drivers provided for Windows 10, 8, 7, Vista, XP, ME, 98, Server 2012, Server 2008, Server 2003, CE.NET (version 4.2 and greater), or RT in 32-bit or 64-bit installations. Also supports Linux, MAC OS X, MAC OS 9, MAC OS 8, Android.

This adapter supplies Optical Isolation & Surge Protection.

Each RS-422/485 port is individually optically isolated with 2000 volt DC optical isolation. The optical protects your PC or notebook from spikes and surges on the RS-422/485 network, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse. Your computer is well protected, since the surges and spikes cannot cross the optical link. Each RS-422/485 port is individually protected by surge protector to withstand electrostatic discharge and power surges up to 25KV ESD. Surge suppression on all signals prevent damages caused by lighning and high voltage.
