2.  After module is powered up, long press this button (“Low” > 4s) and loose to make the module recover to factory setting.

2.2. RS485 Interface
RS485 use two wire links, A(DATA+), B(DATA-). Connect A(+) to A(+), B(-) to B(-) for communication.
Suggest to connect GND together when interference is very severe.
The RS485 interface support maximum 32 RS485 device. The cable maximum length is 1200 meters.
Need to add 120Ohm terminal resistor for over 300 meters.

2.3. Mechanical Size
The dimensions of Protoss-PW11 are defined as following picture (mm):

2.4. Product Installation

2.5. Order Information
Base on customer detailed requirement, Protoss-PW11 provide different configuration version, Details as below:

NETWORK STRUCTURE

3.1. Wireless Network
Product can be set as a wireless STA and AP as well. And logically, it supports two wireless interfaces, one is used as STA and the other is AP. Other STA devices can join into the wireless network through AP interface. So it can provide flexible networking method and network topology.
AP: Wireless access point which is the central joint. Usually, wireless router is a AP, other STA devices can connect with AP to join the network.
STA: Wireless station which is terminal of a wireless network. Such as laptop and pad etc.
3.1.1. AP Network
All the STA devices connect to the device AP transfer data to PLC device. Note the STA devices can not communicate to each other due to PW11 does not support router function, if need this function, use PW21/HF2211/HF2221

3.1.2. STA Wireless Network
Take the following picture as example. When router works in AP mode, product connects to the user’ s devices by RS485 interface. In this topology, the whole wireless network can be easily stretched.

3.1.3. AP+STA Wireless Network
Product can support AP+STA method. It can support AP and STA interface at the same time.Shown as follow:

In this picture, open the AP+STA function and the STA interface can be connected to the remote server by the router. Similarly, the AP interface can also be used. Phone/PAD can be connected to the AP interface and to control the serial devices or set itself.
Through AP+STA function, it is convenient to use Phone/PAD to monitor the user’s devices and not change its original settings.
Notes that:
When the AP+STA function is opened, the STA interface needs to connect to other router. Otherwise, STA interface will endlessly scan the router information nearby. When it is scanning, it will bring bad effects to the AP interface, like losing data etc.
AP and STA parts must set to the different sub-network for the product working as APSTA mode.
Does not support Wi-Fi repeater function that means device works in AP+STA(STA connects to router), PC connects to device AP, but can not access to internet (If need this router function, use PW21/HF2211/HF2221)
3.1.4. IOTService Software
Open the IOTService after PC connect to the AP hotspot generated by product, then config the parameter.

3.1.5. Webpage Configuration
Use PC to connect with product’s AP. Input the default IP(10.10.100.254, default username and password: admin/admin) to login the webpage to configure the parameter.
