RC1180-MPC1
USER MANUAL RC1701HP-MPC1
Example 8 – Example message – Configuration setting message (OTA123, step 2)
You want to update this configuration parameter:
• RF_POWER. Address: 0x01. New value: 0x01 (minimum)
Slave Address: 48 24 12 34 56 78 01 00
Master Address: 48 24 AB CD EF AB 01 00
From the incoming configuration dump message (OTA123, step 1) you read that
the value at address 0x00 was 0x03.
The message from master must then look like this:
Master Manufacturer ID. MSB first
Master Unique ID. MSB first
CI field for the Application Layer.
Long header.
Slave Unique ID. MSB first
Slave Manufacturer ID. MSB first
Old (unchanged) value for Address 0x00
New Value for Address 0x01
You only need to send the configuration values up until the last byte you change.
Bonus:
If your master is an RC11xx-MBUS3/17xx(HP)-MBUS4 you can achieve this by:
• Setting C-field to 0x44 (remember to exit config mode afterwards)
• Sending the following message to the master UART:
0x0F 0xAB 0x78 0x56 0x34 0x12 0x24 0x48 0x01 0x00 0x01
0x00 0x00 0x00 0x03 0x01
• C-field and Master address will then be inserted by module before sending,
and L-field will be adjusted, resulting in the above message.
