7.3.4.2 Bus CAN
The signals of the bus CAN are available on the Micro FIT 16-pin connector and on the cable. (see chapter
3.2.2.3 16-wire micro FIT cable )
The data transmission is done on a differential wire pair. The line is then made with 2 wires,
CANH : Positive differential line,
CANL : Negative differential line.

7.4 Inputs/Output functioning
The
GenPro 53e
provides five Inputs (opto-coupled), three Outputs (open collector) and two analog Inputs
available for an external use.
As an option (contact us) the inputs E3 and E5 can be insulated.
The modem contains the EGM standard library (see the documents
"EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case, these functions can also be controlled by AT commands:
AT+GPIOSET
for a writing access to a GPIO used as an output,
AT+GPIOGET
for a reading access to the GPIO used as an input.
AT+ xxxx
for a reading access of the GPIO used as an analog input. Contact us.
