Device Servers

SENA device servers replace modems with Ethernet over SSL encryption

Modem emulation allows a user to easily configure a networked SENA device / terminal server as a modem. The SENA product emulates modem responses to a serial device in the field and seamlessly sends and receives data over an Ethernet network. Embedded, pre-designed devices can treat the SENA device like a modem, but allow it to "dial up" an IP address instead of a phone number.

A key benefit is the ability to retain legacy software applications and devices without reprogramming devices in the field. Modem emulation also promotes cost savings by utilizing an IP network instead of a PSTN. Modem emulation can be used to replace the modem at both ends of the connection or on just one end using IP sockets.
