Konexio tipikoa
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. 
Fabrika berrezarri
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.

FCC ADIERAZPENA
FCC abisua
Ekipo hau probatu egin da eta B Klaseko gailu digital baten mugak betetzen dituela ikusi da, FCC Arauetako 15. zatiaren arabera. Muga hauek etxebizitza-instalazio batean interferentzia kaltegarrien aurka arrazoizko babesa emateko diseinatuta daude. Ekipo honek irrati-maiztasun-energia sortzen, erabiltzen eta igor dezake eta, argibideen arabera instalatu eta erabiltzen ez bada, interferentzia kaltegarriak sor ditzake irrati-komunikazioetan. Dena den, ez dago bermatzen instalazio jakin batean interferentziarik gertatuko ez denik. Ekipo honek irrati- edo telebista-harreran interferentzia kaltegarriak eragiten baditu, eta hori ekipoa itzali eta piztuz jakin daiteke, erabiltzaileari gomendatzen zaio interferentziak zuzentzen saiatzea, neurri hauetako bat edo gehiago erabiliz:
- Berbideratu edo lekuz aldatu antena hartzailea.
- Handitu ekipoaren eta hargailuaren arteko bereizketa.
- Konektatu ekipoa hargailua konektatuta dagoen zirkuitu desberdineko entxufe batera.
- Kontsultatu banatzaileari edo irrati/telebistako teknikari esperientziadun bati laguntza lortzeko.
Kontuz: Fabrikatzaileak berariaz onartzen ez duen gailu honetan egindako aldaketak edo aldaketek ekipo hau erabiltzeko baimena baliogabetu dezakete.
Gailu honek FCC Arauen 15. zatia betetzen du. Funtzionamendua honako bi baldintza hauen menpe dago:
Baliteke gailu honek ez du interferentzia kaltegarririk eragin, eta (2) gailu honek jasotako edozein interferentzia onartu behar du, nahi ez den funtzionamendua eragin dezakeen interferentziak barne.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/Canada. This device is intended only for OEM integrators under the following conditions: The antenna must be installed such that 5mm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna, As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.
Ohar garrantzitsua: baldintza hauek bete ezin badira (adibidezample, certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling The final end product must be labeled in a visible area with the following: “Contains FCC ID: 2ALHY-C2RMODULE”

Amaierako produktuen etiketatzearen betetze-informazioa
When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily removed. If not, a second label must be placed on the outside of the final device that contains the following text: “Contains FCC ID: 2ALHY-C2RMODULE”. The FCC ID can be used only when all FCC compliance requirements are met.
Proba moduei eta proba osagarriei buruzko informazioa
This transmitter is tested in a standalone portable RF exposure condition and any co-located or simultaneous transmission with other transmitter(s) or for mobile products class II permissive change re-evaluation or new FCC authorization. Host manufacturer installed this module with single modular approval. The test of radiated emission and spurious emission according to FCC part 15C, 15.209, 15.207 requirement, only if the test result comply with FCC part 15C, 15.209, 15.207 requirement, then the host can be sold legally.
Proba osagarriak, 15. zatia B azpiataleko oharra
Igorle modular honek azpisistema gisa probatu du eta bere ziurtapenak ez du estaltzen azken ostalariari aplikatzen zaion FCC Part 15 B azpiataleko arauen eskakizuna. Azken ostalariak berriro ebaluatu beharko du, hala badagokio, arauen eskakizunen zati hau betetzen duelako. Aurreko baldintza guztiak betetzen diren bitartean, transmisorearen proba gehiago ez da beharrezkoa izango. Hala ere, OEM integratzaileak bere amaierako produktua probatzeaz arduratzen da instalatutako modular honekin behar diren betetze-baldintza gehigarrietarako.
Kontuan izan EMI gogoetak
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product that integrates this module. The host integrator must follow the integration instructions provided in this document and ensure that the composite system end product complies with the requirements by a technical assessment or evaluation to the rules and to KDB Publication 996369. The host integrator installing this module into their product must ensure that the final composite product complies with the requirements by a technical assessment or evaluation to the rules, including the transmitter operation and should refer to guidance in KDB Publication 996369. OEM/Host Manufacturer Responsibilities OEM/Host manufacturers are ultimately responsible for the compliance of the Host and Module. The final product must be reassessed against all the essential requirements of the FCC rule such as FCC Part 15 Subpart B before it can be placed on the US market. This includes reassessing the transmitter module for compliance with the Radio and RF Exposure essential requirements of the FCC rules.
Nola egin aldaketak - Ohar garrantzitsua
Baldintza hauek bete ezin badira (adibidezampordenagailu eramangarrien konfigurazio jakin batzuk edo beste transmisore batekin kokatzea), orduan FCC baimena ez da baliozkotzat hartzen eta FCC IDa ezin da azken produktuan erabili. Egoera horietan, OEM integratzailea arduratuko da amaierako produktua (igorlea barne) berriro ebaluatzeaz eta FCC baimen berezi bat lortzeaz.
