General Purpose I/O (GPIO)
The GPIO connector features a Micro-Fit 3.0™ 2 x 8 position connector with a 3.0 mm pitch, manufactured by Molex.
Digital inputs are equipped with pull-down resistors. Additionally, all general-purpose I/O (GPIO) pins, encompassing both inputs and outputs, are safeguarded by transient protection.
The I/O port facilitates the control of up to 4 external devices and the monitoring of 4 external inputs.
The serial data port uses 3 (including common Ground) of the 14 pins configured as Data Communication Equipment (DCE). RS485 uses two pins.
Serial data ports on most computer equipment are configured as Data Terminal Equipment (DTE). In some cases, it may be necessary to insert a “null modem” or “gender changer” in the serial data line in order to correctly connect between the devices.
