Au SAE J1708/J1587 Interpreter

Au J1708 Interpreter

Au SAE J1708/J1587 Interpreter, a palm-size handheld device with J1708/J1587 bus Interface and RS232 Interface, is capable of interpret the most popular SAE J1708/J1587 signals to a RS232 ASCII String (similar to AT command string). Its 9 pin female RS232 connector can be connected to PC or any devices with RS232 serial connections. At the 9-pin “BUS” side (male connector), it can be connected to J1708/J1587 network and a DC power supply (e.g. +12V).

The pin-out of the DB9 male "BUS" Interface is illustrated here:
