The IrDA interface provides a wireless interface to an external printer. This interface
functions in the same way as a normal serial interface except that a modulated infrared beam
is used to exchange data and status information instead of a wire connection. Both the
Monitor and some printers are equipped with infrared transmitter/receiver units.
When using a printer without a built-in infrared interface, for example, the HP DeskJet 420,
an infrared to parallel converter (Jet-Eye, orderable under M3080A Option #H05) is needed.
See the User’s Guide (M3046-9001C-1) , Installation chapter, for details on how to connect
the printer using this converter.

The Wireless LAN interface provides a wireless connection to the Agilent LAN. The
Wireless LAN CPU connects to the wired LAN inside the Monitor and provides the software
drivers for the RF Board. The RF Board transforms wired LAN signals into 2.4 GHz signals
for transmission. The modulation technique FHSS, frequency hopping spread spectrum,
ensures optimum transmission performance.
The 2.4 GHz band is available worldwide for industrial, scientific and medical purposes, and
is called the ISM-band.
