CH20-ROA Hardware Key

The CH20 ROA hardware key allows enabling the DeltaLog13 application software for the use with the HD2402 photo-radiometer datalogger.

The key does not require installation; simply plug it in an available USB port of the PC, and the software will be automatically enabled. In the status bar of the software, the key serial number will appear.

It can be transferred to one PC to another, allowing the software to be used on the PC to which the key is connected, if DeltaLog13 is installed on different computers.

It works with PC running Windows® operating system.

Notes:

- The minimum required version of the DeltaLog13 software is 1.0.1.0.

- If the software is started before the connection of the hardware key, a warning message will appear asking to connect the key, and the software will not start.

- The functionalities of the software are enabled until the key is connected to the PC. If the key is disconnected, a warning message will appear asking to connect the key again.

- DeltaLog13 software recognizes hardware keys having CH20-ROA code only. It is not possible to enable the software with hardware keys having different code supplied with other software.

- For the proper operation of the key, it is necessary that the PC is provided with USB ports. If the PC has no free USB ports, it is possible to increase the number of ports available through an external USB hub that can be easily found at the PC accessories shops.
