2.2.8 USB / Serial Adapter Cable
A USB / Serial adapter cable will convert a USB connection on your PC to a DB-9 serial connec-
tion, compatible with Morningstar devices. Note: Most of these adapter cables come with drivers
which must be installed to created a Virtual COM port (VCOM). This allows the computer to view
a USB port as a serial port. More can be found on VCOMs in Subsection 5.3.2.1. It has been re-
ported that some USB to Serial adapters will not work with either the MSC or our control-
lers. This is usually due to the adapter output voltage being below the RS-232 electrical
specication. Section 11.0 Troubleshooting explains this further.
