III.
Connecting with a Serial Port:
PDA communication with the Global Water family of data loggers is generally done
using a serial port due the greater popularity and larger number of PDA’s with this
capability. This is done with the GL500 and WL16S loggers and requires a serial
adaptor cable, which converts the special connector on the PDA to a standard DB-9
serial port. In the case of the WL16S, the special adaptor cable provided with the
logger is also needed. Some recommendations are:
For the Dell Axim X50, X50V, X51, X51V, X30, X3i and X3, use model number
C-X50V-1F-P adaptor cable available from Global Water or SERIALIO.COM.
For the Hewlett Packard iPAQ rz1715, hx2110, hx2410, hx2750, rx3115, rx3415,
rx3715 and hx4705 series of PDA’s; use model number ISC-21-1700 adaptor cable
available from Global Water or GOMADIC.COM.
While the PDA software will run on any device using the Windows CE or Mobile
operating systems, the serial adaptor cable is also a requirement. It has been found
that some of the cables on the market do not support the DTR (Data Terminal
Ready) pin, which is required to communicate with the data logger. The cables
recommended above are known by Global Water to have this signal wired in. Before
buying cables for other types of PDA’s, consult the manufacturer.
IV. Connecting with a USB Host Port:
Global Water recommends using a serial port to communicate between PDA’s
and the WL16S and GL500 data loggers, however; communication with the GL500
or WL16U using a USB port is possible, provided that the PDA’s USB port functions
in the host mode. Some recommendations for PDA’s with USB host ports are:
Acer n30: Requires no special cable.
Fujitsu-Siemens Pocket Loox 720: Requires no special cable.
ASUS Mypal A730W: Requires a special adaptor cable.
Many other after-market devices can be found for adding USB host functionality to
the more common PDA’s on the market but at the time this manual was written,
Global Water has not tried them and cannot make any recommendations.
