RC1180-MPC1/RC1701HP-MPC1 User Manual (rev. 1.1)

RC1180-MPC1

USER MANUAL RC1701HP-MPC1

Example 8

– Example message – Configuration setting message (OTA123, step 2)

Example

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:

L C

LL_HEADER

APP DATA - LONG TPL_HEAD

_UID

UID

Field

Hex

Comment/Note

0x18

Length. 24 bytes.

0x44

SND-NR

M_MID

0x24 0x48

Master Manufacturer ID. MSB first

M_UID

0xAB 0xEF 0xCD 0xAB

Master Unique ID. MSB first

M_VER

0x01

Master Version

M_DEV

0x00

Other

0xAB

CI field for the Application Layer.
Long header.

S_UID

0x78 0x56 0x34 0x12

Slave Unique ID. MSB first

S_MID

0x24 0x48

Slave Manufacturer ID. MSB first

S_VER

0x01

Slave Version

S_DEV

0x00

Slave General device

0x01

Access Number

0x00

Status Byte

0x00 0x00

Configuration Word

DATA

0x03

Old (unchanged) value for Address 0x00

DATA

0x01

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.
