5 Ethernet protocol
Using the protocol described below, the PT-104 can be controlled directly through the Ethernet port without using the usbpt104 DLL.
5.1 Enabling the Ethernet module
By default the Ethernet module is disabled to save power. To enable it, plug the connector into a USB port and use the Ethernet settings application installed with PicoLog. Once an IP address and port are assigned, the module will be enabled. The unit may then be used by powering from USB or PoE.
5.2 Finding Ethernet PT-104s
To discover all PT-104 data loggers on a network:
·
Send a UDP packet to port 23 from port 23 (telnet) to destination 255.255.255.255 with this character string:
fff
(three bytes of 0x66 - that is, 0x666666)
·
All PT-104s will reply from port 23 to port 23. The data will be the string:
PT104 Mac:XXXXXX Lock:Y Port:ZZ
where:
XXXXXX is the 6-byte MAC address of the PT-104 replying Y is 0x00 for unlocked and 0x01 for locked ZZ is the port it will listen on (two bytes, MSB first).
5.2.1 Commands
To lock a PT-104 to a machine, send a UDP packet containing the data string lock destined for the device's listening port and IP address. This is required before the PT-104 is usable.

·
[hex] 0c XX XX XX XX 0d XX XX XX XX 0e XX XX XX XX 0f XX XX XX XX data from channel 4
A unit that has been locked will reply Lock Success or, if currently locked by this machine, Lock
Success (already locked to this machine).
Converting is an acknowledgment of any convert request received. Once a setting has been made the unit
will continue to convert and send back data. This means there will be incoming data approximately every 720 ms. To stop all converting, send a converting command with data 0x00 to turn off all channels.
USB PT-104 USB/Ethernet RTD Data Logger Programmer's Guide 17
Copyright © 2010–2017 Pico Technology Ltd. All rights reserved. usbpt104pg r8
After receiving the lock command via UDP, a 15 s timeout will start and a keep-alive packet must be sent in this time. The Alive response is the acknowledgment. Try to send a keep-alive packet every 10 seconds to allow time to retry if no acknowledgment is received.
If any request is made from another machine while a unit is locked, the response will be PT104
Mac:XXXXXX Lock:Y Port:ZZ as explained in Finding Ethernet PT-104s.

5.5 To calculate a resistance
·
Read the EEPROM to obtain the calibration information for the channels.
·
Take measurement 0, 1, 2 and 3 on a channel.
·
Note that measurements are stored MSB-first while calibration values are stored LSB-first.
·
Then: result = (channel calibration * (measurement 3 - measurement 2))
/(measurement 1 - measurement 0)
·
To convert to a resistance, divide result by 1 000 000.0.
For other measurement types see the Protocol information in the Serial Port PT-104 User's Guide.
