Frame synchronization is accomplished by inserting the character 0xB5 in the beginning of frame.
If another character 0xB5 should appear in the frame, then it is replaced by the following DLE
sequence:
DLE sequence
Character
0xC500
0x85
0xC501
0xC5

Mode of Connected device: MASTER
Transmission control timeout [ms]
Number {0 – 65535}, default = 11500
Master timeout. This timeout is reseted after receiving of an answer from Slave or a frame incoming
from the connected master.
Mode of Connected device: SLAVE
Response timeout [ms]
Number {0 – 16383}, default = 300
Slave’s response timeout - waiting for response, otherwise the reply to master is resend.
Repeats
Number {0 – 7}, default = 3
Number of repeats when the response from master is not received
Break mode
(additional parameter)
Master, Slave Plus
Break validity time [ms]
Number {0 – 5000}, default = 1000
Slave, Slave Plus
Break length [ms]
Number {0 – 128}, default = 2
Length of break in ms
7.1.3.3.13. RDS
RDS protocol is a protocol used in MRxx networks. It supports network communication; any node in
the network can talk to any other (unlike Master-Slave type of protocols). The RDS protocol is typically
used when combining RipEX and MRxx networks or SCADA networks adapted to MRxx networks.
