Overview
P4S-342 is an industrial programmable I/O board. You can build various network communication
systems connecting P4S-342 to many devices such as sensors and actuators. We provide a self-
development programming language, which is called PHPoC, for programing P4S-342. This language
is easy to use and compatible with PHP which is widely used script language.
※ PHPoC is basically compatible with PHP but those languages are not the same because of
restrictions about embedded system. Refer to the PHPoC Language Reference and PHPoC vs PHP for
detailed information.

Peripherals (JP1)
Analog Input: ADC
P4S-342 provides 6 ADC input channels.
To use the ADC, the reference voltage input is required. When VDDA-AREF jumper is connected,
3.3V is connected to the reference voltage input pin.
※ VDD-AREF jumper is connected on the P4S-342 when shipped from the factory.
When directly inputting the reference voltage without using JP4, input it with the AREF pin.
※ Caution: Inputting a voltage to the AREF pin while the VDDA-AREF jumper is connected may
cause the product to malfunction. Therefore, before connecting the voltage to the AREF pin, make
sure that the jumper is NOT connected.

Digital Inputs/Outputs: UIO
P4S-342 provides 24 digital I/O ports including 22 universal I/O ports (numbered 0 to 21) and 2 LED
ports (numbered 30 and 31). Two LEDs on board are assigned to number 30 and 31. The pins
numbered 0 to 21 can be available to be set digital input or output but note that pins which are
shared with serial interfaces (numbered 0 to 13) cannot be available to use a digital input or output
while they are being used by the serial communication (UART, SPI and I2C).
