Single-port serial device server with internal modem

The Digi 70001899 connects one RS-232/422/485 serial device to an Ethernet network and adds an internal v.90/v.92 modem for dial-up access. Three RJ-45 ports and one RJ-11 port provide the physical interfaces. The unit measures 3.3 by 5.3 by 1 inches and weighs 2.25 ounces. A 12 VDC power supply and a crossover cable are included.

Suits sites needing one serial port and dial-backup

This model fits installations that require a single serial connection with modem fallback over a phone line. It does not suit applications that need multiple serial ports or purely Ethernet-connected serial devices without dial-up capability.

One RJ-11 port for dial-up connectivity

The single RJ-11 interface is the only path for v.90/v.92 modem communication, so the part is only appropriate when a telephone line is available for remote serial access.

Questions about this item

Does the 70001899 require an existing Ethernet switch or router to connect to my LAN?

Yes, the unit has four RJ-45 ports for Fast Ethernet, so a switch or router with an available port is needed for network connectivity.

Can the internal v.90/v.92 modem on the 70001899 share the same phone line as my legacy analog modem?

The RJ-11 port connects the internal modem to a standard phone line; it cannot operate simultaneously with another modem on that line.

How can I verify the 70001899 serial port is communicating correctly after installation?

Connect a serial device using the RS-232/422/485 switch-selectable port and confirm data passes through the Ethernet or dial-up link.
