V. System Requirements:
Desktop or Laptop computer with:
1) Windows 98, ME, 2000, XP Vista or Windows 7 Operating Systems
2) CDROM Drive
3) RS-232 COM Port (for WL16S) or USB Port (for WL16U)
Note that the software provided with the WL16 data loggers is for running on
desktop and laptop computers only. Software for many popular
Handheld PDA
devices is available from Global Water. Special cables may be required.
VI. Software Installation:
Global Logger Installation: This software is for use on Windows based desktop
and laptop computers only. Insert the software installation CD and run the Setup
program. This will install the Global Logger application in the Program Files folder
and automatically put the Global Logger icon on the desktop.
Serial communication (WL16S Only
): If you are using the RS-232 serial port to
access the data logger, no further action is needed. You can start using the logger
by opening the Global Logger application program. Skip the next section.
USB Driver Installation (WL16U Only): With the installation CD in the
drive
and DC power applied to the logger, plug the USB cable into the data logger to
CDROM
open the ADD New Hardware Wizard. The menus that follow will look different for
different operation systems but the procedure is the same. Do not allow the
Hardware Wizard to automatically search for the driver. Instead, specify the
location (CDROM). If a generic driver gets, or has been previously installed, it must
be uninstalled before proceeding by using the Add or Remove Programs section of
the Control Panel. Instead, click the Search External Media box or Specify a
Location
box and install the driver from the CDROM. Running the Setup program that installs
the Global Logger software also installs a folder with the driver in it. This location can
also be specified if the CDROM is not available; although, it is recommended that the
driver be installed at the same time the Global Logger is installed.

WL16U Only
The following menus apply to the Windows XP operating system.
1) Do not let Windows search
for software. Click “No, not
at this time” when asked if
Windows Update can search
for software.
Click Next.
2) Do not let Windows automatically
install the software. Click “Install
from a specific location”.
Click Next.
3) Specify the location of the driver.
Make sure the Global Logger CDROM
is in the CD drive and click “Search
removable media” only.
Click Next.

4) The Hardware Wizard searches
for the driver.
If Windows advises that the software
is not certified, click:
“Continue Anyway”.
This only means that Microsoft has not
licensed the software. Second party
software is allowed and no harm will
come to your computer.
5) The first half of the installation is
complete. The Hardware Wizard
must make two passes.
Click Finish.
6) Two drivers might be required so the Hardware Wizard may repeat the exact
same process again. As before; a: do not let the Windows Update do a search, b:
tell Windows to search from a specific location instead of automatically installing
software, c: tell Windows to search from removable media (CDROM).
7) The installation is complete.
Click Finish.

8) To confirm the installation, look in the
Device Manager and find the USB Serial
Port. The COM setting following that will
show the virtual COM port that has been
automatically assigned to the driver. As
you will see in the following sections, this
COM port will be automatically detected
by the Global Logger software so it is not
necessary to note which port is being
used by the driver.
VII. Direct Connection:
Important: This data logger supports an Auto Baud Rate Mode which automatically
detects the communication speed. However; this communication software also
supports loggers which may be programmed in a Fixed Baud Rate Mode. This is
useful in telemetry applications, particularly when using Global Water data loggers
with our Global Access radio modem software. The upcoming discussion assumes
that the logger is programmed in auto detect mode. If you cannot connect to the
logger and suspect that the logger may be using a fixed rate mode; try each
connection speed separately, especially 38400 which is required when using the
Global Access software.
There are 3 ways to connect to the WL16 data Loggers, direct connection through
the RS-232 serial port (WL16S only) or USB port (WL16U only), as well as dial out
through an installed modem (requires WL16S only with external serial modem).

To make a direct connection to the logger, click the “Direct” option and from the
“Port” menu, select the port you wish to use.
For USB access (WL16U) select the USB serial port at the COM port the driver was
assigned, which is automatically shown in the list as “Global Logger USB Device”.
Serial connection (WL16S) is generally done using the serial cable provided with the
logger through the 9-pin COM1 connector at the back of the computer although
COM2 can also be used.
Next, select the desired baud rate from the “Baud Rate” menu. Generally, the fastest
rate of 115,200 is used although; long cables or other factors may require a slower
setting. Click “Connect” to make the connection. If a connection is not made, an
error
message will appear. Check the battery, communication cable,
installation
VIII. Modem Connection (WL16S Only):
and COM port settings.
driver
Access to the WL16S can be made through dial-out to a remote modem by clicking
the “Modem” option. The connection from modem to logger requires an RS-232
serial modem, USB modems are not supported as an interface to the logger;
therefore, the WL16U logger cannot be accessed by modem. Also, some switch
settings must be made to the remote modem and an initialization file may be
required to properly configure the host modem.
