5. S is the length of the transmitted message. The setting value should be in the range of 0~8 with the unit of byte
3
(8bits). If the setting value (<0 or >8) exceeds the range, the instruction will run at the minimum value 0 or the
maximum 8. If the length of the transmitted message is 0, the communication mode will automatically change into
the slave mode to receive messages without sending out any data. The mode can be used to monitor the
communication packet.
6. S is the starting device where transmitted data are stored and only the following 8 bits of data are used.

For example, 4 messages are transmitted with D10 as the starting device. See the data transmission sequence as
below.

beforehand based on the 2.0A/2.0B mode. If the Msg. ID is not specified, please clear the value of D
before receiving data.
