CommandPort – TCP/IP port that responds to Link Manager commands.
(typically port 1000)
HTTPPort – port where the Link Manager will respond to HTTP requests.
UDPPassThruPort – port to receive UDP PassThru packects. If the devices
does not want to receive UDP PassThru packets, then the device will
set
UDPPassThruPort to 0.
DeviceMAC – MAC identifier of the device
Locator - character that represents where a sensor packet entered the
repeater network. (" ", "a"-"z" and "A"-"Z").
Version – firmware version of the device
UDP PassThru & Wifi Sensor UDP Packet
Point Six Wireless Wifi sensors send a standard sensor packet contained in a UDP
wrapper. This UDP wrapper contains information about the sender. See the
document “
Point Six Wireless Transmitter Packet Data Specification
” for
information about the standard sensor packet. Wifi sensors normally send UDP
packets with a command of 2. The Wifi Sensor Utility has a mode where it will send
UDP packets on behalf of a sensor using command 5. The host application (like
Link Managers, OneSix OPC Server or other applications) will respond with the
UDP Host Acknowledgment packet. The acknowledgment packet allows the Wifi
Sensor Utility to confirm that a host is receiving the UDP packets.
Where

Cmd – (1 bytes) Command: 2 – UDP Sensor Data; 5 – UDP Sensor Data
asking for host ack.
PktCnt
+
– (2 bytes) packet count. The device will increment this count
every time it transmits a UDP PassThru packet.
MAC – (18 bytes) device MAC address. If the MAC address does not apply
this field will contain a unique identifier for the device. If not used,
this field will be set to all zeros. (ex: “00:23:b4:39:03:47”) (NULL
terminated)
MediaDest – (8 bytes) specifies what media the Link Manager will send the
sensor packet (Sensor Pkt) to. The Media Designations are listed
below and placed consecutively. If no Media Destinations are specified
the field will contain a single NULL and the sensor packet will be sent
to those media that are in Pass-Thru mode. Example: “TSR”
