Attention
Setup available for LW8 (LoRaWAN) references Software 1.7 Revision A.3 or prior.
The following information applies to the ACW / LW8-DINRS
In this operating mode, the ACW / LW8-DINRS is seen as a Modbus master on the RS232 or RS485 serial link.
✓
1: Serial parameters: The ACW / LW8-DINRS module has a serial link that can be set in RS232 or RS485
mode. You must also specify the speed (Baudrate) you want to use: 4800, 9600, 19200, 38400, 57600,
and 115200 are available. The other default and non-configurable parameters are: 1 stop bit, no
parity, no flow control and 8 data bits.
✓
2: LoRa parameters: Check 'Enable OTAA' to activate the 'Over The Air Activation' mode. Uncheck
'Enable OTAA' to activate 'Activation By Customization' mode.
✓
3: Modbus parameter: 'Timeout' is the maximum response time of the slave. If the slave does not
respond before this time, the message will be considered as erroneous and will not be sent on the
LoraWan network. Also specify the 'Function Code' function code that you want to use.
