What it does

The Digi International 70001806 PortServer TS 2 MEI connects two serial devices to an Ethernet network using switch-selectable RS-232/422/485 interfaces. It provides three RJ-45 ports for 10/100 Mbps Fast Ethernet connectivity and includes a power supply for wall-mountable installation.

Sustained operation

The unit handles continuous serial data streams at up to 230 Kbps across both ports while maintaining 100 Mbps Ethernet throughput. Management via SNMP, Telnet and HTTPS allows remote monitoring and diagnostics without interrupting the serial-to-network bridging function.

Interface limits

Fast Ethernet caps network bandwidth at 100 Mbps, so aggregate serial traffic cannot exceed that ceiling. The three RJ-45 ports share the same 10/100 Mbps backbone, and serial signalling is limited to the 230 Kbps maximum per port with no higher-speed serial modes available.

Questions about this item

How much power does the 70001806 draw when running continuously?

The unit ships with an external power supply; the device itself weighs 2.25 oz and has no internal fan, so heat output is minimal during all-day operation.

What cabling and network infrastructure must I already have to use the two serial ports?

You need a 10/100 Mbps Ethernet switch with a free RJ-45 port and standard Cat5 cabling; the server provides switch-selectable RS-232/422/485 on its two DB-9 ports.

Will the 230 Kbps serial rate work with my legacy RS-422 equipment?

Yes — the serial interfaces are switch-selectable between RS-232, RS-422 and RS-485, supporting legacy gear at up to 230 Kbps over the 10/100 Mbps Ethernet uplink.
