C1 + M1
devices are interconnected by four interface lines:
, C1 devices do not have dedicated ground and power lines.
Sometimes, such lines are just not necessary. For example, Tibbit #27 (IR
receiver/transmitter) works fine without the ground and power:
Some C1 devices, such as
(power input) do need to be connected to the
system ground. Tibbit #18 was designed to be used with power supply Tibbits
and
. These "M" devices provide ground on their pin 5, and this solves the
problem. Incoming supply voltage (Vin) is routed through pin 1:
