Wire Connections

Wiring Cable 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 slot S2 of a 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 Cable Probes and their Tibbit counterparts.

The only adjustment that the app may need is the speed of the I²C communications for Cable Probes 1~3. As the cable of these Cable Probes moves the sensing ICs away from the CPU, the I²C clock frequency needs to be lowered. We recommend an ssi.baudrate of 100.

Wiring Cables Probes to Other Hardware

Although Cable Probes are primarily intended for use with TPS devices, they can also be wired to other hardware. When connecting to third-party hardware, remember to add a pull-up resistor (of about 2KΩ) to the SCL line of Cable Probes #1~3 (this is not necessary for wiring to TPS devices).
