Use of a PC
Apart from the normal use of Deckman software to control WTP3 in the normal racing environment there are
other times when it is necessary to communicate with WTP3 via a PC. Direct le modications, le backup, le
restore and diagnostics can be carried out via PC using Deckman, FTP or HyperTerminal (or similar terminal
program).
Communication Options and conguration
Ethernet
The Ethernet interface allows much faster data transmission than a standard serial link and used as the method
for interfacing Deckman. The Ethernet interface on WTP3 transmits normal function data to PCs running
Deckman via the UDP protocol , UDP is available to any PC in the correct IP range on the network.
Any PC on the Ethernet can control the WTP les, calibrations etc. This is controlled via a TCP/IP protocol so that,
in the case of multiple PCs running Deckman, only one copy of Deckman has access to the les at a time and
only one copy of Deckman can act as the navigational server.
Note: The navigational server option is controlled via the congure comms dialogue.
The Ethernet port is congured by default. It is only necessary to congure the instrument type within Deckman
(gmenu – change instruments) as ‘WTP2 Ethernet’ and set the network properties on the PCs used to match the
WTP3 IP addressing. It is recommended that the xed IP address is retained (192.168.0.2) and the PC(s) on the
network are set to IP addresses 192.168.0.3 onwards. The Subnet Mask on the PC should also be set to match the
WTP3 , usually set to 255.255.255.0. This can be changed to suit the individual requirements of the boat.
The IP Address of the WTP3 is set in the network.d le.
Note: For an example of this le please see: Data les.
Advanced Calibration via Deckman
Using the Advanced Calibration, Advanced Damping and WTP Guru functions in Deckman the user can directly
modify calibration, lter and system les.
Note: It is recommended that advanced users use FTP to modify system les rather than WTP Guru and the advanced
le editors within Deckman. However these utilities are very useful to take a quick look at the le content while sailing.
Caution: incorrect modication of the WTP3 les (especially system les accessed by the WTP Guru option) can lead
to incorrect data values or system instability. Only modify les directly if you are familiar with the le level operation
of WTP3. Common settings, calibration and damping can be carried out in the normal Deckman Instrument Control
dialogues. It is recommended that regular backups are made of your WTP3 les using FTP.
