PHPoC P5H-155 Programmable IoT Gateway Device User Manual

PHPoC P5H-155 Programmable IoT Gateway Device

Overview

The P5H-155 is a programmable device that provides Ethernet function. Because this product equips 2 digital output ports, you can remotely control two relays via 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. 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

Digital Output
2 digital output ports are an 6-pole(5mm pitch) terminal block. Each port is mapped a specific pin of UIO0 for programming. Normal Open
It means that the output port default is OFF. This method can be used by connecting user equipment to COM terminal and NO terminal of each output port. The maximum allowable current is 5A at DC 30V.

Normal Close
It means that the output port default status is ON. This method can be used by connecting user equipment to COM terminal and NC terminal of each output port. The maximum allowable current is 1A at DC 30V.

LED
This product has 8 LEDs. The user-defined LEDs are turned on when you output LOW to the UIO pin connected.

Function Button
The function button, which is inside the hole of the side panel, is used to operate this product as a button setup mode.

USB Device Port for connection with PC
The USB device port is to connect with PC. You can access to P5H-155 via development tool by\ connecting USB cable to this port.

Software (IDE)

Connecting Product

USB Connection

•  Connect the USB device port of P5H-155 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-155 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

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.
