OBD-II Interfaces
ScanTool
ScanTool.net offers these OBD-II interfaces:
- ElmScan ISO
- ElmScan VPW
- ElmScan PWM
- ElmScan 5
Purchase the version appropriate for your car. You will need an OBD-II cable, and a serial adapter to connect the PDA serial cable to the ElmScan serial connector.
Multiplex Engineering
Multiplex
Engineering offers these OBD-II interfaces for PDAs:
- T16-006
- T16-003 (shown here)
The OBD-II protocol is software selectable. The hardware supports ISO, VPW, PWM, and KWP. These interfaces plug directly into a serial PDA cable. The T16-006 requires an OBD-II cable; the T16-003 has an integral OBD-II connector. Multiplex offers the T16-009 which also supports the CAN protocol, but is not yet supported by OBD Gauge. Support for the T16-009 will be added in a future version.
Car-Pal
The
Car-Pal OBD-II interface connects
wirelessly using Bluetooth. The module plugs directly into the OBD-II connector
of the vehicle. No cables are needed when used with a Bluetooth capable Palm,
Pocket PC, or Windows PC. ISO, SAE, KWP and CAN bus protocols are supported.
OBDPro
The
OBDPro Serial Scantool is compatible with
OBD Gauge and offers support for all OBD2 protocols (ISO, VPW, PWM, KWP,
and CAN).
blueOBD
Build
your own blueOBD OBD-II interface,
featuring a wireless Bluetooth connection, and a tiny form factor.
OBDKey
The
OBDKey vehicle interface uses either
Bluetooth or USB 2.0 and plugs straight into the standard OBD connector in your
car. OBDKey provides wire free diagnostics with Bluetooth or is supplied with a
