PHPoC P5H-151 IoT Gateway Device

Overview

The P5H-152 is a programmable device that provides Ethernet function. Because this product equipped a serial port which can be selected to RS485 or RS422, you can connect a variety of serial devices to a network.
Programming on this product requires the use of PHPoC (PHP on Chip). PHPoC is quite similar in syntax to PHP, the general-purpose scripting language. Therefore, anyone with experience in programming can easily learn and use it.
Although PHPoC and PHP are quite similar in syntax, they are clearly different programming languages. Refer to the PHPoC Language Reference and PHPoC vs PHP for detailed information.

Supplying Power

DC 5V Input
This port is the input port for supplying power. The input voltage is DC 5V(±0.5V) and the specification is as follows:

Ethernet

Ethernet port supports 10/100Mbps Ethernet. This port is an RJ45 connector and it is mapped to NET0 for programming.

Serial Port

The type of serial port of P5H-152 can be selected to either RS485 or RS422. This port is a 6-pole terminal block and is mapped to UART0 for programming.
Setting flow control is required to use RS485 on UART0. For more details, please refer to the PHPoC Device Programming Guide for p40 document.

Connecting Product

USB Connection

Connect the USB device port of P5H-152 to your PC via a USB cable.
Run PHPoC Debugger
Select connected COM PORT and press connect ) button.
If USB is successfully connected, connect button will be inactivated and disconnect button ) will be activated

Remote Connection
P5H-152 provides the remote connection. Please refer to the PHPoC Debugger manual page for details.

Reset

Settings Reset
Settings Reset makes all settings of your PHPoC products to factory default.

Settings Reset Procedure

Step	Action	Product State	STS LED
1	Press function button shortly (less than 1 second)	Button setup mode	On
2	Keep pressing the function button over 5 seconds	Preparing initialization	Blink very rapidly
3	Check if the STS LED is turned OFF	Initialization ready	Off
4	Release the function button right after the STS is OFF.(※ If you don’t release the button within 2 seconds, the state go back to the step 3)	Progressing initialization	On
5	Rebooting automatically	Initial state	Off

Factory Reset
Factory Reset makes all settings of your PHPoC products to factory default including a password. Futhermore, all files stored in flash memory are deleted as well as certificate. Because of this, you have to backup your files before doing Factory Reset. To progresss the Factory Reset, the PHPoC Debugger is required.

Factory Reset Procedure

Web Interface

PHPoC itself has a webserver to provide a web interface. When receiving a HTTP request, it executes the php script in the requested file (if there) and respond to the client. Webserver is independent of PHPoC main script. TCP 80 is used for web server and you can use the interface via Internet Explorer, Chrome or any other web browsers.

How to use web interface
To use the web interface, “index.php” file should be in the file system of your PHPoC. Connect to this page by entering device IP address after connecting it to network.

If the name of file is not “index.php”, just specify the name of file after the IP address with slash mark.

Practical Use of Web Interface
Since the web server executes the php script in the requested file, user can put php code in the in the requested file to interact with peripherals. It is worth noting that there is other way to interact with the peripherals in real-time from web interface. This can be done by using websocket.

Setting Passwords

If you set a password for the product, you must enter the password when connecting the product via USB or network.
Please refer to the PHPoC Debugger manual page for details.

Escaping Infinite Reset

PHPoC basically runs scripts when it boots up. Therefore, it is possible that a PHPoC cannot be escaped from infinite reboot when script contains system command such as “reboot”. To solve this problem, it is required to stop the running script.
Refer to the following.

Entering ISP mode
Make your PHPoC product to enter ISP mode by supplying power while pressing FUNC button. In the ISP mode, you can access to PHPoC by PHPoC Debugger without running a script.
Connect to PHPoC
Connect a PC to PHPoC via a USB cable and connect to the port via PHPoC Debugger. A message window related with ISP mode will be popped up.
Reboot PHPoC
Reboot PHPoC by using “Reboot a product” menu in PHPoC Debugger. After rebooting, PHPoC stops running script even it is not in the ISP mode.
Correct source code
Correct the source code to prevent infinite reboot state.
