CCDBusTransceiver
Development board for interfacing Chrysler's legacy CCD-bus (no CDP68HC68S1 chip needed).
To be used with CCDLibrary.
The Chrysler CCD/SCI Scanner Firmware and GUI works with this hardware. There are obvious limitations of course and there may be connections issues but worth a try.
Wiring (V1.XX):
| PCB | Arduino Mega | OBD2 connector | |----------|--------------|-----------------| | J1 GND | GND | | | J1 TX | RXD1 + D3 | | | J1 RX | TXD1 | | | J1 +5V | +5V | | | J2 CCD- | | J1962-11 | | J2 CCD+ | | J1962-3 | | J2 GND | | J1962-4 |
Connect TBEN jumpers if standalone operation is needed without a compatible vehicle.
Disconnect TBEN jumpers when connected to a live CCD-bus network in a compatible vehicle.
Wiring (V3.XX):
| PCB | Arduino Mega | OBD2 connector | |----------|--------------|-----------------| | 5 CCD+ | | J1962-3 | | 6 CCD- | | J1962-11 | | 7 GND | GND | J1962-4 | | 8 RX | TXD1 | | | 9 TX | RXD1 | | | 13 CTRL | D3 | | | 14 +5V | +5V | |
