uninstall, and then hit the tab key. It will show all the installed packages that match those letters at

5.4.5 Command Line Instructions (CLI)
Command Line Instructions can be used to control and monitor the functions of the hub and
attached devices. To use the command-line interface a serial terminal emulator must be installed on
the host computer. Examples include PuTTy, Serial, ZTerm, and Minicom. If you would like more
information, please look at our more in-depth information here:
Two example commands can be seen below, you can use these commands to check hub information
and health.

5.5. Scalability
If you wish to synchronise more devices, multiple PDSync-C4 can be connected together (either in a
star topology or daisy chained) to allow up to 20 devices to be managed from a single host computer
simultaneously
In order to daisy-chain multiple PDSync-C4, each PDSync-C4 needs to be connected to mains power
individually and the first PDSync-C4
in the chain should be connected to the local computer through
the "host port". The host port of the next board in the daisy-chain is then connected to any of the first
PDSync-C4 downstream USB ports. More boards are added in the same way.
Using this daisy-chain approach, a maximum of three additional boards can be linked, allowing a total
of 20 devices to be sync'd from a single host computer.
For more information on endpoints, connecting multiple devices and calculating how many devices
you can connect to your host system please see our
on endpoints.
5.6. Cooling the PDSync-C4
The safety features of the product include an over-temperature feature that causes the board to
temporarily shut down when the board temperature exceeds 65°C board temperature can be
measured using a temperature sensor placed at the location shown in the diagram below.
Temperature can also be monitored via our API, Cambrionix connect App and the command line
interface. When measuring temperature to determine if forced cooling is required, the temperature
should be measured whilst the PDSync-C4 is under
full load and at the highest ambient operating temperature.
Forced cooling may be required if the board is operated inside an enclosure and/or at high ambient
temperatures. We recommend using a fan monitoring fan flow-rate and position to ensure the unit
remains below 60°C.
