Sensorsoft ST6105J User Manual page 7

When connecting a Sensorsoft Thermometer to a serial port or device/console server, configure
the port as follows:

1200 bps, 8 bits, no parity, 1 stop bit

Turn off autobaud

Flow control set to "None"

Non-telnet binary (raw) transfer mode

Assert RTS and DTR always
If using a device/console server, refer to its documentation for more details on the above.
Note the physical port number where you plugged the cable into your computer or device/console
server. If the Sensorsoft Thermometer is being plugged into a Windows based computer that has
only one COM port, the port number is usually COM1. If you are using a USB to serial adapter,
you need to refer to the operating system's serial port (COM) listing. In Microsoft Windows, this
is usually "Device Manager->Ports (COM&LPT)." In Linux or UNIX, refer to the /dev/tty
directory.
