1. Overview WL-C2400 provides safe RF wireless communication with Point-to-Point Topology. WL-C2400 is an RF wireless communication module operating in the 2.4GHz ISM Band Frequency Hopping method and can apply to equipment using serial interface, and long distance communication is possible at high speed. WL-C2400 can be configured according to the required type by AT command. Applications are conveniently configured and can be applied in various fields. 1.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes: (1) l’appareil ne doit pas produire de brouillage, et (2) l’utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.
1.2 Characteristics and fucntions The main performance features of WL-C2400 are as follows. 2.4MHz ISM Band Frequency Hopping Operation Link rate : Max. 250kbps Can be set by AT command UART / USB interface Call book function . 1.3 WL-C2400 Specitication Electrical / General Supported Frequency: 2.402 ~ 2.480 GHz Spreading Method: Frequency Hopping (FHSS) Output Power: Min.
2 Hardware Description This document defines the standard and general characteristics applied to the WL-C2400 module. WL-C2400 composes several interfaces as follows. Input DC voltage : +5 VDC Power LED indication : RED RS232 / UART Data Interface Antenna (SMA) USB Port (Serial to USB (Micro 5Pin)) I/O Pins (JST Connector 6Pin (VCC / TX / RX / GPIO1 / GND / GND)) Fig 1.

4 Installation There are several factors to consider when preparing to deploy a wireless network, and several factors are described below in no specific order. 4.1 Network Topology WL-C2400 operates in 2.4GHz ISM band and supports Point to Point Topology. 4.2 Throughput WL-C2400 supports up to 250kbps asynchronous transmission speed 4.3 Distance Physical distance between products is affected by required antenna performance and height 4.
5 User description 5.1 POWER SUPPLY The module supply power is +5V, and the user should consider the current capacity when applying power. 5.2 UART PORT It processes transmission/reception data by connecting it to the UART Port of the connecting device. Fig 5. PWR/UART Connector 5.3 USB PORT USB PORT is an added function for user convenience, and it is directly connected to the PC without using a separate conversion device. Also, power can be supplied through the USB port without a power supply.
5.4 LED status indication LED status indication is as follows Item Description Number of LED TX RF data transmission status indication 1 EA RX RF data reception status indication 1 EA POWER Module power status indication 1 EA ＊ In command Mode, only the power LED is on Fig 7. LED indication 5.5 ANTENNA When using the WL-C2400, it is recommended to use the antenna listed below. Item Type Part name Gain (dBi) 1 Dipole antenna W5E-WO-01 4.5 ± 1 Fig 8.
