RS232 Interface
The millisKanner is configured and controlled through its RS232 interface(s). It is
equipped with two RS232 interfaces so that a number of millisKanners can be controlled
by a single milliK precision thermometer (or other measuring instrument) by ‘daisy-
chaining’ them together with RS232 null-modem cables. The millisKanner responds
identically to data received on the two RS232 ports so they are completely
interchangeable. Even in a system in which a number of millisKanners are daisy-chained
together, the cables to the two RS232 ports may be reversed without any impact on the
operation of the system.
