GE Grid Solutions MDS Master Station - IP Payload

MDS 05-6399A01, Rev. F MDS™ Master Station 51
- Peer to Peer Enabled – If enabled, the AP will allow enabled peers to send
traffic through the AP to other enabled peers by rebroadcasting their
transmissions to all other remotes in the system.
- Ethernet Rebroadcast Type – When rebroadcasting peer-to-peer Ethernet
traffic, only the selected type of traffic will be rebroadcast to other remotes on the
network.
• Remote Options:
- Rebroadcast Serial – If enabled, serial traffic originating from this device will be
rebroadcast by the AP to other remotes in the network. The AP must have peer-
to-peer rebroadcasting enabled.
- Rebroadcast Ethernet – If enabled, Ethernet traffic originating from this device
will be rebroadcast by the AP to other remotes in the network. The AP must have
peer-to-peer rebroadcasting enabled.
IP Payload
Under the IP Payload menu, up to three instances of the IP Payload service may be configured.
The IP Payload service can operate in 4 different modes:
- TCP Server
- TCP Client
- TCP Server/Client
- UDP
Common Options:
• Enabled – Set to true to enable this IP Payload configuration.
• IP Payload Mode – The mode in which this instance of the IP Payload service should
operate. The details of these modes are shown below.
• Talk on VRC – (Only in packet-with-mac mode) The Virtual Radio Channel that data
from this IP Payload instance will be tagged with when transmitted over the air.
• Listen to VRC – (Only in packet-with-mac mode) Over-the-air data tagged with this
Virtual Radio Channel will be handled by this IP Payload instance.
• Modbus TCP RTU Conversion – (Does not apply to UDP mode) When enabled, the IP
Payload server will convert packets between MODBUS TCP and MODBUS RTU
formats.
• Inactivity Timeout – When set to a value larger than 0, the connection will be closed
after the specified number of seconds without any data activity.
Each of the IP Payload modes have different use cases and configuration options, as described
below:
TCP Server:
The TCP server mode allows IP connections to be established with the Master Station. Data
received on this TCP socket will be transmitted over the air to remote SD radios as if the data
was received on the payload serial port of the Master Station. Over-the-air serial data originating
from a remote SD radio will be transmitted out of this TCP socket. This mode of operation can
be thought of as a ‘remote terminal server’, not to be confused with the SD remote radio’s
Terminal Server functionality.
