PRECAUTIONS I , .
Congratulations on your purchase of this SHARP
CE-133T level converter.
By connecting this level converter between the
Organizer with a serial 1/0function and a personal
computer or peripheral device with an RS - 232C level
converter, information can be interchanged between the
Organizer and the personal computer. Except for the
input and output levels, the serial 1/0 functions of the
Organizers conform to the RS-232C standard. This level
converter adjusts the input and output levels to the
RS-232C standard.
SPECIAL NOTICE
• The level converter is designed to comply with the EIA
(Electronic Industries Association) standard.
However, we can notguarantee that the level
converter will work with all so-called "RS-232C
compatible" devices . Carefully study this manual
together with the Organizer operation manual and the
manual for the other device you wish to communicate
with until you are fully acquainted with the protocols
and specifications of all these devices .
