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 either the Cisco® 2.4 GHz 802.11b
DSSS WLAN radio or Symbol® Technologies Spectrum24 FHSS 2Mb 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.
