Mesh Network set up
。 Make sure the following parameters of all of the Parent (coordinator) and Child node (router) to be the same for the same group.
1. PAN ID (group name)
2. Radio channel number
3. Network Name
4. Encryption key
。 Short Address for all of Child nodes ID must be different each other.
8
Communication Configuration
The bit rate means the communication speed between Parent and Child. Please keep at the high speed 115200 bps. Don’t change any
parameters on this page.
Protocol Setup
RS485 Modbus/RTU configuation
Make sure the protocol type as “Modbus (RTU)”
1. “Station number analysis” is an option if Child nodes are connected with Modbus sensors
9
2. A “Station no. list” has to be set with the sensors ID (Station number) corresponding to the short address of Child node and
“Save to module”.
For example:
。 Sensor Modbus ID1/ID2 are connected with Child node short address 0001
。 Sensor Modbus ID3/ID4/ID5 are connected with Child node short address 0002
。 Sensor Modbus ID6 is connected with Child node short address 0003
RS232 ASCII set up
RS232 (1-to-1) set up
Configuration:
1. Select “No” for “Station number analysis” on Parent device.
2. Make sure packet filtering is set at “Yes (notification type)” for Parent and Child devices.
10
RS232 (1-to-N) set up
Parent configuration:
1. The station number analysis needs to enable and setup the station no. table as the description on the page 7/8.
2. Please select “Other(ASCII)” as protocol type
3. “Start character code 1” and “Start character code 2” can be set by demand; The initial start character code1 setting is "25".
4. “Station number start position after character code” is to specify the number of bytes that follow the start position
character code.
5. “Station number store area”: Select the number of bytes (1 to 4) for the area where the station number is stored.
6. “Station number size”: Select the number of digits from the end of the station number (1 to 4)
7. “Station number type”: The format of (Decimal ASCII/Hexadecimal ASCII) can be selected for the station number.
8. “Delete the beginning of transmitted data”: While transmitting the data to the child node, can be set to delete the specified
number of bytes (0 to 15 bytes) from the beginning of the receive data by child nodes,
