Wire Connections
Wiring the Probes to TPS devices
This wiring scheme ensures compatibility with Tibbits of similar functions. For
example, let's suppose that there is a Tibbo BASIC/C app that works with Tibbit #29
(ambient temperature meter) plugged into the slot S2 of the TPS2 device. Then,
replacing this Tibbit with Tibbit #21 (four terminal blocks) and wiring a Cable Probe
#01 to this terminal block as shown above will allow the app to run unchanged. The
same applies to other Probes and their Tibbit counterparts.
The only adjustment that the app may need is the speed of the I2C communications
for Probes 1~3. Since the cable of these Probes moves the sensing ICs away from
the CPU, the I2C clock frequency needs to be lowered. We recommend the
ssi.baudrate of 100.
