7.1.2.3.13. 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 M!DGE3 and MRxx networks or SCADA networks adapted to MRxx networks.
Frames are received from the Radio channel and sent to COM1-3 or Terminal server 1-5 according to
UDP port settings and vice versa - from wire to radio channel.
ACK
List box {On; Off}, default = "On"
Frame acknowledgement when transmitted over wire (COM or Ethernet) interface. ACK (0x06)
frames are transmitted on successful reception and NAK (0x15) on unsuccessful frame reception.
ACK timeout [ms]
Number {0 – 16383}, default = 1000
Note
ACK timeout is measured from the beginning of the packet transmission.
When "ACK" is enabled, M!DGE3 is waiting "ACK timeout [ms]" after transmitting frame to receive
acknowledgement. If the ACK frame isn't received, the frame is re-transmitted. Frame re-transmission
happens up to "Repeats" number of times.
Repeats
Number {0 – 31}, default = 3
Number of frame re-transmissions.
Local response address
Number {0 – 255}, default = 0
This address is used only with status query (0x51). Response of M!DGE3 is "0x54 <Local response
address> 0x00".
