TSN Box Development – TSN Box 3.0 Getting Started Guide
2.4.17 Earth/Chassis
This connects directly to the unit'schassis. It is important to equalize the ground potentials of devices when using
T1 connections with isolated power supplies since the T1 connections are not isolated themselves, allowing
possible voltage transients to damage the T1 ports when a cable is connected. Always ensure that the unit has the
same ground potential to connected T1 devices by connecting the chassis to a ground/chassis connection of the
connected device(s).
2.4.18 Thermal Considerations
Always ensure that the two ventilation openings at the top of the unit is unobstructed.
At present temperature control is limited to the fan speed being set to a low static value after startup; dynamic
control shall be added in the near future. A very low fan speed was elected for minimal noise, yet still guaranteeing
safe operation at standard 20℃ laboratory conditions with acceptable margin.
If the unit is to be operated at elevated ambient temperatures, please contact support for appropriate fan control
adjustment.
2.5 Software (Web based)
2.5.1 Prerequisites
• Host PC with a modern web browser.
• CAT5e/CAT6 cable to connect the host PC to the unit.
2.5.2 Getting started
Power up the unit as described in the hardware chapter. Refer to the Hardware Setup Guide provided with the
unitto ensure the hardware is not configured in a potentially harmful manner.
2.5.3 Network discovery
By default, the unit you received has an IP address 192.168.41.XX/24 where XX are the last two digits of the unit's
serial number. In the event that the unit is booted into recovery mode using the recovery button, the unit's IP
address defaults to 192.168.41.250/24.
The unit has a web interface that can be used to configure and perform basic functions. The unit advertises itself
using Zeroconf <https://en.wikipedia.org/wiki/Zero-configuration_networking>_. Several tools are
available to discover the IP address of a board(s) connected to their LAN segment. If a python installation is
available, connected unitscan be discovered as follows:
from zeroconf import ServiceBrowser, Zeroconf
