Description
OBDII is an international standard for
communication between automobiles and
diagnostic testers.it specifies a serial data
communication bus between ECUs and diagnostic
test SAE OBDII Scan Tool ( SAE j1978 ).
The OE90C2600 provides an inteligent interface
between a Host and the vehicle’s Electronic
control units. Both LEDs display the current
communication status and connected information.
OE90C2600 is developed to meet the ISO 15031-
5 standard with ISO9141,KWP2000,SAE j1850
and CAN Bus protocols in Service 1..9

it is recommended to use a brown out device ( e.g TL7705 from TI ).
• the both LEDs are low current If < 5 mA.
• close jumper to download a new release.
• Don’t change the value of crystal.
• LED yellow indicates everytime a frame exchange occurs. LED green is on if a valid protocol is found.
