If the panel looks like figure 9, then do one of two things, depending on what kind of connection you are using:
USB connection: Press the Reset button on the MS-2000 back panel. If this does not work then you have to either use a real serial port or use a serial adapter, e.g., Keyspan™ USA-19HS Serial Adapter. Serial adapters can often be obtained at local stores.
Serial port connection: Turn power off then on again.
Note that as soon as the panel looks like Fogure 10 the firmware is being erased.
If using a USB connection, do not disconnect, turn off power, or otherwise interrupt the firmware loading when the panel looks like Figure 10. To do so will make firmware loading impossible with the USB connection.
If the direct USB connection stops working due to loss of firmware, the Keyspan USB-serial adapter will work.
