Some are 10 pins others are 14 pins.

14 pins connector

The 14 pins connector appears to be very popular amongst all penenabled wacom sensors.

The 14 pins connector appears to include both a USB port and a USART (Serial) port.

Trashie successfully connected the USB port using the TabletPC drivers. Note that the board requires a 3.3v supply. The board appears to support a 5V (USB power) supply but requires that a “Zener” diode is installed for this to work (look for a ZD1 marking). All the boards we have seen so far did not have the zener installed. So something is required to be able to convert the 5V USB power to 3.3v. See Trashie's thread about it.

NOTE: There might be hints that boards are *EITHER* USB or USART instead of “boths”. We are not sure if boards can have both interfaces or is it just “programmed” on way vs. the other way.

Considering all the info we have so far:

Pin# Name Signal Direction Wire Color (USB) Notes
1 USB Ground1 Black Shield or signal ?
2 USB Ground2 Brown (also seen Black) Shield or signal?
3 USB D- (twisted pair)
4 USB D+ (twisted pair)
5 USB power (5V)? Red
6 ? Orange or Blue
7 DTR Tablet ← Host unconnected
8 RTS Tablet ← Host unconnected
9 RXD Tablet → Host unconnected
10 TXD Tablet ← Host unconnected
11 GRD **Tablet ←?→ Host yellow/green Trashie sets that to VCC for the board to start sending data. Undersampled did nothing for that one, but we have noted contradictory directions for this(?)
12 PLTRS1 Tablet ← Host green active low enable? Trashie did not have to connect this for it to work(?)
13 PCB VCC 3.3v Red VCC Supply
14 PCB Ground Black

10 pins connector

(gleaned from a disconnected SU-017-X01 from a Compaq tc1100)

Pin# Name Direction Notes
1 +3.3vdc test point markings says +3vdc – mA never seen above ~25mA @3.3v
2 RXD Tablet → Host Serial data packets - runs at 19200 baud N-8-1
3 TXD Host ← Tablet Serial data (commands & queries)
4 ? No clear output activity. When applying VCC: weird behavior (current draw goes down to 0mA then jumps to 46mA, sounds illegal/scary)
5 ? No clear output activity. When applying VCC or Ground makes no behavior difference. Ugly signal on pin when applying VCC.
6 Ground
7 ? not connected on tc1100
8 ? not connected on tc1100
9 ? not connected on tc1100
10 ? not connected on tc1100
