5.8 Updating the PT-100’s Firmware

Firmware updates for the PT-100 are provided to improve performance, ﬁ x issues, and to add

new features or change functionality. Firmware updates are periodically available for download

on our website (

www.SensataPower.com). This website also provides an Instruction Sheet that

gives a detailed step-by-step procedure for successfully downloading and installing the update.

The PT-100 controller uses a USB Micro-B port/connector (see Figure 5-4) to connect a Windows-

based computer to download a ﬁ rmware updates.

Note: Installing new ﬁ rmware resets your PT-100 controller to its factory default settings.

However, if used in a standalone installation (i.e., not networked), the DIP switch settings will

reload. If networked with a Magnum inverter and remote, your original settings are retained in

the remote and will reload once the PT-100 is reconnected to the network.
