Digi Connect Wi-EM™
The Digi Connect Wi-EM (Wireless Embedded Module) device server is a fully customizable and
secure 802.11b wireless embedded module that provides integration flexibility in a variety of
connection options. Based on the common platform design approach of the Digi Connect family of
embedded products, the Digi Connect Wi-EM minimizes design risk and reduces time to market by
allowing customers to easily accommodate both wired and wireless network functionality in a
single future-proof product design.
The Digi Connect Wi-EM wireless embedded module is pin-compatible with the Digi Connect
EM, and makes fully transparent 802.11b integration possible without the traditional complexities
of hardware and software integration work.
Built on leading NetSilicon 32-bit NET+ARM technology, the Digi Connect Wi-EM combines
true plug-and-play functionality with the freedom and flexibility of complete software
customization using the proven NetSilicon NET+Works development platform, and offers a
seamless migration path to a fully integrated NetSilicon system-on-chip solution.
The Digi Connect Wi-EM Integration Kit is available to help customize the look-and-feel of the
device interface.
Digi Connect™ ES 4/8 SB and Digi Connect 4/8 SB with Switch
Digi Connect ES provides mission-critical serial over Ethernet connectivity. It is the first IEC
60601/EN60601 compliant device of its kind and consists of four or eight galvanic isolated RS-232
serial ports, with a 10/100 Mbps network interface and, for Digi Connect ES 4/8 SB with Switch, a
four-port Ethernet switch. Applications include providing Ethernet connections from serial devices
such as ventilators, EKGs, patient monitoring systems, infusion pumps and glucose meters to the
central data management system.
Galvanic isolation provides extended electrical safety. There is no electrical path for current to
earth ground, ensuring no electrical shock when making physical contact with the Digi Connect
ES. There is no electrical path from port to port, ensuring a ground fault will not affect the
operation of the Digi Connect ES or the operation of any device connected to it.
Digi’s patented RealPort technology makes it possible to establish a connection between the host
and a networked serial device by creating a local COM or TTY port on the host computer.
Incoming/outgoing and Telnet sessions on each port give system administrators a high level of
control over networked serial devices.
