Advantage
The data output on the receiver is continuous, it meets the requirements for MODBUS continuous transmission and low
latency.
Disadvantage
The baud rates on both receiver and transmitter must be same. The module will raise its air data when the baud rate is raised,
thus the receiving sensitivity will be lowered and operation range will be shorter.
Applications
Applicable for those applications not requiring distance but continuous data and response time.
Note
1. The “wireless air data rate” in the configuration commands is invalid (SPED.210 bits) and software will calculate
automatically.
2. 0000 and FFFF are the broadcast addresses, which can be used to monitor and broadcast.
3.
The addresses and baud rates must be same on both receiver and transmitter.
4.
In continuous mode, both transmitter and receiver must be same model. For example, E70 (868T14S) and E70 (868T30S)
cannot communicate in continuous mode.
6.4 Sub-package Mode (Mode 2)
Status
M0=0 M1=1 M2=0
Transmitting
Wireless data transmission is available.
Receiving
Wireless data receiving is available.
Baud rate &
air data rate
Under this mode, the baud rate and air data rate are independent, both receiver and transmitter can have different baud rate but
same air data rate.
Advantage
Very low air data rate can be configured for longer distance, the data continuousness between output data depends on the data
packet length.
Disadvantage
Since the air data rate is low and the receiver needs to wait for the data packet length or timeout byte numbers, it may caus e
some delay, which depends on the actual value as set.
Applications
Applicable for those applications requiring distance and continuous data while not requiring transmission speed.
Note
1. Air data rate and baud rate are not relative; the values are valid.
2. 0000 and FFFF are the broadcast addresses, which can be used to monitor and broadcast.
3. The addresses and air data rates must be same, but baud rates can be different on both receiver and transmitter.
4. The size of individual data packet depends on the subpackage size CHAN [7:5] (excluding address and channel for
directional transmission)
6.5 Configuration Mode (Mode 3)
Status
M0=1 M1=1 M2=0
Transmitting
Transmission not available, serial data received will be discarded.
