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, driver
installation and COM port settings.
VIII. Modem Connection (WL16S Only):
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.
