Sharp CE-170TS serial cable for Zaurus

Sharp CE-170TS is a null modem serial cable for Zaurus. It seems to be actually the only available IOPORT serial cable working with the latest Zauruses (it requires only 3.3V power).

Opening the case requires a bit of violence. The cover is fastened by a drop of glue on one or two places. After breaking them it easily opens and closes. My attempt did not cause any case damage.

It is a bit expensive, but poorly designed anyway. It expects that other side provides full RS-232 levels output, but accepts low levels input. Output voltage does not conform RS-232 standard. Some pins are even directly connected to the low voltage side! It means that the cable provides no ESD or voltage protection! However it works nicely as a null modem with a standard PC and using a special null modem gender changer it works with a RS-232 hardware modem. It does not work with mobile phone or GPS client cables.
