52 MDS Master Station MDS 05-6399A01, Rev. D
Repeater With Local Data – This is the same as “Repeater” but should be used when
data-collection devices such as serial RTUs will be attached directly to the repeating Master
Station.
Serial Payload Port – The front-panel serial port that will be used for serial payload communications.
This can be set to either COM1 or COM2, the default value for this is COM1.
NOTE: Serial port settings such as baud rate and byte format are located under services serial
ports.
Encryption – When the Master Station is being using in a network of only SD radios, over-the-air (OTA)
encryption may be enabled. The Master Station uses AES-128, passphrase-based encryption to secure
both payload, and Dlink traffic. If the radio is operating in transparent mode, there is a separate
passphrase for payload and Dlink traffic. If the radio is operating in packet or packet-with-MAC mode,
there is a singular passphrase for all traffic.
5.6.5.1.2 Dlink
Dlink is a GE MDS-proprietary protocol used for diagnostics communications.
Unit – This parameter identifies the radio in the wireless network with a specific ID during diagnostic
sessions. For compatibility with legacy devices, the value must be 10000 or greater (2710 in
hexadecimal).
Dlink Type – This setting identifies the radio as a Node, Root, Repeater, Peer, or Gate. Each of these are
operating modes of the transceiver with respect to diagnostic/management activities.
Mode – Configure if Dlink will operate on a serial port, or via a TCP socket.
Serial Mode Settings:
Serial Port — This setting determines which serial port to use COM1 or COM2. This
must be different than the serial payload port.
TCP Mode Settings:
TCP Port – The TCP port that the Dlink service will listen on.
IPv4 Addr – Optionally configure the service to only attach to the specified IPv4
Address. This is useful when traffic is being separated into data and management
VLANs. If no value is specified, the service will accept connections on all configured IP
addresses.
IPv6 Addr – Optionally configure the service to only attach to the specified IPv6
Address. This is useful when traffic is being separated into data and management
VLANs. If no value is specified, the service will accept connections on all configured IP
addresses.
Enabled – Enable or disable diagnostics functionality. Setting it to ON configures the radio to pass the
diagnostic link protocol (DLINK) over the radio’s COM2 management port.
