SiteChart can connect to one Explorer. In order to connect two instruments, you
must run two copies of SiteChart. You will also need a second serial port. If you
do not need to control two instruments at the same time, you may want to connect
one instrument to the computer, download the information, disconnect it and then
connect the second instrument.
Connecting Multiple Instruments
1. Start SiteChart and connect the communications cable to the first Explorer.
2. Open the Communications menu and select Setup .
3. Select the serial port to which the first Explorer is connected.
4. Ensure the first instrument is communicating with SiteChart.
5. Start another copy of SiteChart and connect the communications cable to the
second Explorer.
6. Open the Communications menu and select Setup .
7. Select the serial port to which the second Explorer is connected.
8. Ensure the second instrument is communicating with SiteChart.
SiteChart was designed to accept data from multiple instruments so the log directory
is divided into sub-directories. Each sub-directory will correspond to information
received from a single instrument. These sub-directories are created using the
instrument serial numbers. For example, if one instrument has the serial number
“123”, then all the information received from this instrument will be recorded in a
sub-directory of the data directory called “123”. The path would be C:\Program
Files\SiteChart\Data\123\filename.PID.
