Introduction The WU5108 is an IEEE802.11b/g/n mini-size USB module that can connect the BP300 printer equipped with a USB Pin Connecter (Figure 2-1). The module has a core WiFi chipset, AR9271 which is produced by Atheros Communications, Inc. The WU5108 delivers reliable, cost-effective, feature rich wireless connectivity at high throughput from an extended distance. It supports WMM and WMM-PS (IEEE802.11e QoS standard); also has an innovative built-in WPS (Wi-Fi Protected Setup) function which can build a connection between an AP and synchronize the encryption settings. 2. Features The WU5108 Module supports various Operating Systems and several Network Environments. Table2-1 explains the types for the systems. <Table 2-1> WU5108 Specification Standard IEEE 802.11b/g/n standards compliant Antenna Internal Antenna Supported OS Windows 2000, XP, Vista, WIN7, RTOS(ThreadX) Interface with External PCB USB2.0/1.1 Security WEP 64/128 WPA, WPA2 Frequency Range 802.11b/g/n USA(FCC): 2.412GHz ~ 2.462GHz Europe(ETSI): 2.412GHz ~ 2.472GHz Japan(TELEC): 2.412GHz ~ 2.472GHz Number of Selectable Channels 802.11b/g/n: USA(FCC) 11 Channels EU(ETSI) 13 Channels Japan(TELEC) 13 Channels Data Rate 802.11b: 1,2, 5.5, 11Mbps 802.11g: 6,9,12,18,24,36,48,54Mbps 802.11n: up to 150Mbps - 5 - Transmit Power 802.11b : 16 +/-1 dBm(Typical) 802.11g : 13 +/-1 dBm(Typical) Wireless-N : 13 +/-1 dBm(Typical) Physical Specifications Weight : 2.5g Dimension : 32.4(L)*16.6(W)*2.9(H) Environment Specification Operating Temp : 0 to 40 (Celsius Degree) Storage Temp : -20 to 70 (Celsius Degree) Operating Humidity : 10% to 90% Non-Condensing Storage Humidity P : 10% to 95% Non-Condensing Power Requirement Standard USB Power DC 5V Power Input Method Printer Type : Soldering with a connector between the module and the Printer(BP300)  Figure2-1 <Figure 2-1> Connection between WU5108 and Main PCB - 6 - <Information> Applicant : Prinics Co., Ltd Address : E-1101, Digital Empire B/D, 980-3, Youngtong-Dong, Youngtong-Gu, Suwon-Si, Korea Manufacturer : AboCom System, Inc.

It communicates with an external Main Printer PCB by using standard USB2.0 interface (Fiqure2-1). When the adopter power is applied to the printer, it will be supplied to WU5108 via USB 2.0 Power Pin (5V Pin in the USB2.0). <Figure 3-1> WU5108 Block Diagram - 7 - 4. Installation The BP300 Printer has an ARM926EJ CPU and 4MByte Flash Memory for a program execution file. The Module driver is already embedded in the file. The execution file is produced from compiling the ARM based codes, and then it is flashed in the flash memory using a flash memory writing equipment. When the printer has Power-ON, the module has 5V power from the printer PCB via USB connector (Figure4-1). <Figure 4-1> BP300 Printer System Block Diagram WU5108 Module Main PCB DC1250 (ARM9Core) Flash(4MB) DDRII(128MB) Step Motor IC DC Motor IC USB2.0 Conne…
