Dolphin 7400/7450 RF Terminal
The Dolphin 7400 and 7450 RF terminals integrate the basic functionality of the Batch terminal with a radio frequency interface
that allows the terminal to communicate with a host computer via a wireless local area network (WLAN).
Dolphin 7400/7450 terminals have one Type II PCMCIA card slot to allow for an interface with the Cisco 2.4 GHz 802.11b DSSS
WLAN radio.
The Cisco radio uses direct sequence spread spectrum (DSSS) technology, which spreads its signal continuously over a wide
frequency band, and provides an Ethernet-like data rate of up to 11 megabits per second.
The security of wireless networks is greatly enhanced with the use of LEAP (Dynamic WEP), an industry-leading, centralized
security solution developed by Cisco. LEAP combines several innovations including dynamic, per user, per-session WEP and
integrated network logon to promote secure hassle-free enterprise deployment.
The radio may also provide up to 128-bit Wired Equivalent Privacy (WEP) encryption. WEP is used to encrypt and decrypt data
signals transmitted between Wireless LAN (WLAN) devices. The optional WEP security mechanism is available with 128-bit or
40-bit encryption.
Dolphin 7400/7450 RF is interoperable with other 802.11b WiFi-compliant products such as printers and PCs via PC-card
adapters.
Refer to Chapters 1 and 2 in this manual for more on basic operation of the Dolphin terminal.
