Description
ISO14230 is an international standard for
communication between automobiles and
diagnostic specifies a serial data
communication bus between ECUs and diagnostic
test SAE OBDII Scan Tool ( SAE j1978 ).
The OE90C1100 provides an inteligent interface
between a Host and the vehicle’s Electronic
control units. Both LEDs display the current
communication status and connected information.
K and L lines can be connected to ISO BUS
eighter via transistor or transceiver chip. The logic
level on K and L lines can be inverted. The ISO
baud rate is 10400 .
