Modem Emulation (Digi One TS and PortServer TS 2/4 MEI only)

Modem emulation enables a system administrator to configure a networked Digi device server to act as a

modem. The Digi device server emulates modem responses to a serial device and seamlessly sends and receives

data over an Ethernet network instead of a PSTN (Public Switched Telephone Network). The advantage for a

user is the ability to retain legacy software applications without modification and use a less expensive Ethernet

network in place of public telephone lines.

To use a Digi device server for modem emulation, do the following:

• use a cable with the correct wiring pinouts (see See “Modem Emulation Cable Signals” on page 37.)

• configure the serial ports and device type with the Web Interface

Note: Before AT commands are accepted, DSR must go high on the Digi device server.
