Setting Configuration Addresses for Ethernet
Follow these steps to configure the MiniCapt Remote Microbial Air Sampler to
communicate with the Host application by means of an Ethernet network.
CAUTION
As with any network-capable software, do not attempt to connect the MiniCapt
Remote to a network without your network administrator’s cognizance and
explicit permission. The administrator will need to approve, and in most cases
will issue, addresses.
To configure the sampler:
1
Connect the MiniCapt Remote to a computer that has terminal emulation software.
2
Start the terminal emulation software and select the appropriate Serial Port on your
PC. Windows Device Manager may be used to find the required setting.
3
Set the following communication parameters:
