DTLink Hubs have high bandwidth (200k) modules installed.
Assuming that DTLink module (200k) is installed properly in the logger socket of the data logger, (matching outline, not shifted). In the data logger wireless settings, 200k high bandwidth module will need to be selected. Rather than the RSTAR low bandwidth module which is about 9kbps.
Steps are below:
The XBEE Radio should be a HJP900 200k USA/Canada radio.
The DTLink hub address and Network ID should match the DTLink Hub.
This might not work because the data logger is actively logging or their may be other issues.
The best way to check it is to connect to the logger using hyperterminal (or another Terminal program such as YAT - free download on the internet), (921600 baud, 8N1) and send the following commands:
You should get the following response from “XINIT -1” if the module is configured
- XINIT -1,+++,,+++,OK,115200,AT AP,1
Otherwise you will get
- XINIT -1,+++,9600,,….
If response is a) send the command:
XINIT 2400 201 115200
If response is b) send the command:
XINIT 2400 201 9600
You should get the response
AT AP 1,0,OK
AT BD 7,0,OK
Send the following commands
AT 2 1 //Initialized module settings
AT WR //Write ID to permanent memory.
AT ID #### //Replace #### with correct network ID matching hub network id
AT WR //Write new ID to permanent memory
XBEE 9 //Reset to XBEE module and reload memory parameters
