DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015
- 14 -
The iAir App and DL-300 Utility search the logger by broadcast, therefore only the
devices on the same subnet can be searched out. It means that the host PC, Android
devices and the logger must have the same broadcast address. The broadcast address
for an IPv4 device can be obtained by performing a bitwise OR operation between the
bit complement of the subnet mask and the IP address for a device. In other words, take
the device's IP address, and set to '1' any bit positions which hold a '0' in the subnet
mask.
For example, in an entire IPv4 subnet, the host PC or the Android device uses the
private IP address space 172.16.0.0/12 and subnet mask address 255.240.0.0, the
broadcast address is 172.16.0.0 | 0.15.255.255 = 172.31.255.255. Only the loggers
which have the same broadcast address could be searched out in the iAir App or
DL-300 Utility. Please contact with your network administrator to make sure the DL-300
logger is connected to the same sub-network that your Android devices or PC is
connected to.
For connecting with PC via RS-485 network
The DL-300 logger can connect to the PC through a RS-485 network with power input
