Sambungan biasa
The Pepper C2R Module can be connected to a host (computer or another device) using USB or UART0. Both interfaces can be used for communication using the binary protocol described below.
The Module also has secondary UART (UART2) available. Using this connection, the user can view output logs which contain additional information about temporary executing commands. The default configuration is : baud: 115200, Data: 8 bit, Parity: none, Stop bits: 1 bit, Flow Control: none. Data lines can be configured to work using any free GPIO’s available on the module. Additionally, it can be used to operate the RS485 interface with hardware flow control using the DE and Re lines (pin no. 15 and 16).
The Pepper C2 device can be connected directly to a host computer using a standard USB interface. In the same way it can be powered to operate as a standalone device by using power sources such as a USB charger or power bank.
The computer operating system should recognize this device as a virtual com port or USB serial device and it should appear in Windows device manager as a COM port. 
Figure 3-1. Typical connection
Hint – If you don’t have a USB-UART converter to see the logs on the UART2, you can temporarily change the default log interface from UART2 to UART0 in the Cx-client UART configuration button. Then, the logs should be available on the USB port
HID keyboard emulation
The RFID reader can be configured to enable USB port emulation of the HID Keyboard profile. With this functionality, UID numbers of tags read during polling are transmitted as a keyboard input stream to any host device that accepts USB keyboards. To activate this profile, the Cx-client application should be used to select the HID Keyboard profile for the USB port within the USB/UART configuration menu.
Once the device is configured via the USB/UART0 interface in HID Keyboard mode, further connection to this port using the Cx-client application becomes unavailable. In order to temporarily restore the binary protocol, the BUTTON pin should be held at the LOW state for 3 seconds. During this process, the device’s RGB LED blinks once every second and flashes red when the default UART emulation profile has been temporarily restored. Additionally, configuration options allow enabling automatic transmission of the ENTER key after each UID is sent. 
Tetapan semula kilang
To restore the device to its factory default settings, the button pin must be held at LOW state for 10 seconds. The device will indicate the completion of the factory reset process by flashing the RGB LED in white.
