When using USB to control the pump, the address fi elds in command messages are used
to address individual pump channels. As each USB connection is a point-to-point link
between the controlling device (PC) and the pump, there is no need to provide pump
addressing in the communications protocol.
Some parameters apply only to each pump, and so individual channel addressing is not
necessary. When using USB, an address must still be provided each of these messages, but
this address will be ignored.
