6.2.2 S102 Serial Baud Rate
S102 is used to set the baud rate of the data serial port. When the serial port rate is changed, please note that the serial port baud rate of the device connected to the VCAN1878 should be modified.
6.2.3 S103 Orifice Speed
| Te mau faufaa (te mau) |
| 0 – 172800（ Default ）1 – 2304002 – 2764803 – 576004 – 115200 |
The S103 determines the communication rate of the entire network. Each device on the network must be configured to the same rate. The higher the rate, the higher the network throughput, but the worse the sensitivity. The sensitivity difference between adjacent modes is about 1dB.
6.2.4 S104 Network Address (ID)
| Values（0~4294967295） |
| Parau 1234567890 |
All devices on a network must have the same network address. Devices with different network addresses do not communicate with each other. When multiple networks are operating simultaneously in the same area, the network address of each network must be guaranteed to be unique.
6.2.5 S105 Unit Address
| Values（0~65535） |
| Parau 0 |
On the same network, unit address is used for identification on the network, and each device should have a unique unit address.
For a point-to-point network, the default value is 0. The device automatically assigns the unit address. Users do not need to set this parameter. Users can also manually assign the non-0 unit addresses. In the same network, if automatic allocation is used, the unit address of all devices is set to 0. If manual assignment is used, you can set the unit address S105, synchronous address S118, and target address S140 for each device to ensure that the network topology is correct.
For a point-to-multipoint networks, each device must be manually assigned a non-0 device address. No te mau haamaramaramaraa hau atu, see Section 8.7.
6.2.6 S108 Output Power（dBm）
| Values（dBm） |
| 30- 3W 33- 5W 35- 7W 40 – 10W（ Default ） |
S108 is used to set the transmitting power of the local device.
6.2.7 S110 Serial Data Format
| Te mau faufaa |
| 1 – 8N1（ Default ） |
The data format of the serial port supports only 8N1.
6.2.8 S113 Packet Retransmissions
| Values（0~255） |
| Parau 3 |
This register determines the maximum number of times the packet can be retransmitted. The number of the retransmission is used to ensure the robustness of the system in complex environment or weak signal. Retransmission can cause additional data transfer, which can reduce system throughput. The maximum number of packet transmissions is the number of data retransmissions plus one.
6.2.9 S114 Repeater Index
| Values（1~254） |
| Parau 1 |
In point-to-point mode, the register takes effect when the working mode is repeater and the unit address is 0. This register indicates the relative position of the repeater on the network. No additional configuration is required on the master and slaves to add or remove repeater devices on a point-to-point network. When the repeater device is started, it automatically connects to the point-to-point network, and when it is shut down, the network is reconnected.
When multiple repeaters are used, please ensure that the serial numbers of the repeaters from the master to the slave increase monotonously, which can be discontinuous.
6.2.10 S118 Sync Address
| Values（0~65535） |
| Parau 0 |
You can set the synchronization address of the master device and the slave device to specify the synchronization address of the current device from the local device (S105) to the device (S118).
On the point-to-point network, when the local address (S105) is set to 0, the address is automatically assigned, and there is no need to set the synchronous address. When the local address (S105) is not 0, the synchronous address must be set to determine the network topology.
On a point-to-multipoint network, you must manually set the correct synchronization address for each device.
No te mau haamaramaramaraa hau atu, see Section 8.7.
| Values（dBm） |
| -255 ~ 0（read only） |
6.2.11 S123 RSSI From Master RSSI（dBm）
Indicates the received signal strength of the slave or repeater. The value corresponds to pins RSSI1, RSSI2, and RSSI3.
S123 of the repeater device indicates the signal strength of the upper device, and S124 indicates the signal strength of the lower device.
| Values（dBm） |
| -255 ~ 0（read only） |
6.2.12 S124 RSSI From Slave RSSI（dBm）
Indicates the received signal strength of the master or repeater. The value corresponds to pins RSSI1, RSSI2, and RSSI3。
S123 of the repeater device indicates the signal strength of the upper device, and S124 indicates the signal strength of the lower device.
| Te mau faufaa |
| 0 – Point to Multipoint (point to multipoint)1 – Point to Point (point to point) |
6.2.13 S133 Network Type
This register is used to set the network type. On one network, the network type of all devices must be the same.
- Point-to-multipoint：The master broadcasts data to all devices, and all slave devices send data back to the master. （ There can be 0 or more repeaters）
- Point-to-point：Only master and slave endpoints communicate with each other. （There can be 0 or more repeaters）
6.2.14 S140 Destination Address
| Values（0~65535） |
| Parau 0 |
The master and repeater devices can set the destination address, which is used to specify the address of the child device connected to the local device.
On a point-to-point network, when the local address is set to 0, the address is automatically assigned without setting the target address. When the local address is not 0, the destination address must be set to specify the network topology.
On a point-to-multipoint network, you must manually set the correct destination address for each device.
No te mau haamaramaramaraa hau atu, see Section 8.7.
6.2.15 S141 Repeater Y/N
| Values（0~1） |
| 0 – without repeater（Valid only on the master side ）（Default）1 – with repeater（ Valid only on the master side ） |

6.2.17 S143 Faahororaa no te faaohipa i te GPIO
| Te mau faufaa |
| Faaohipa i te tapa'o S114 (Default)A faaohipa i te GPIO[4:1] no te faaite i te numera o te api parau |
No te faaohie i te tapiti-faahou-raa ia taui i te numera o te ana'iraa, e nehenehe ta outou e numera i te numera o te matini ma te faaohipa i te GPIO [4:1].
Ia tae'ahia te matahiti i te 143 0, the repeater sequence number is the value of S114, which ranges from 1 no te 254.
Ia tae'ahia te matahiti i te 143 1, the repeater sequence number is GPIO [4:1]+1, which ranges from 1 no te 16.
If GPIO is used as the repeater number, the repeater number ranges from 1 no te 16. No reira, a maximum of 16 repeaters can be configured.

The master provides synchronization signals for the whole network to ensure that all devices can communicate normally.
The slave end is the final node of the network and communicates directly with the master or repeater. When there is no user data transfer in the point-to-point network, the slave device will only synchronize with the master and will not send any information in the network.
The repeater can extend the coverage area of the master and forward the data. The repeater synchronizes with the master or the upper-level repeater and sends synchronization signals to the lower-level devices. The repeater device can also be used as a slave to send and receive data through the data serial port。Te mau haamaramaramaraa no ni'a i te mau haamaramaramaraa, o te mau haamaramaramaraa ana'e ïa i haponohia mai e te matini i ni'a e aita te reira e horo'a mai i te mau haamaramaramaraa no ni'a i te matini raro roa a'e.
