Agency Compliance and Approvals FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20cm may be maintained between the antenna and users.
Radio Frequency (RF) Exposure Information The radiated output power of the Wireless Device is below the Industry Canada (IC) radio frequency exposure limits. The Wireless Device should be used in such a manner such that the potential for human contact during normal operation is minimized. This device has also been evaluated and shown compliant with the IC RF Exposure limits under mobile exposure conditions. (antennas are greater than 20cm from a person's body).
1. Introduction Product Introduction The RF-WKD is an 802.11 a/b/g/n Wi-Fi module which supports 2 dual-band external antennas. The module provides serial UART interface, enabling connection to any embedded design utilizing a 32-bit microcontroller via simple commands. The RF-WKD Wi-Fi module is compatible with other devices that use 802.11 a/b/g/n technology. For more information, please refer the contents in this document.

3. AT command Convention For every AT command its response is a status, the default response should be an ASCII character byte starting from ‘0’, ‘0’ indicate the request is done successfully , others indicate independent status, but ‘1’ may indicate the request is not complete in certain circumstances. For every AT command its input is defined, the input option with underline indicate the default value for the module. Angle Brackets (“<” and “>”) indicate the value in the brackets is an arbitrary string.

Status 3.14.1.
4. Network command Format To ensure all transfers over UART are operating as expectation, each transfer is required to include the following fields: ● An Opcode which defines the specific operation, the operation may be different between the Printer and the Module. ● A transfer size designates the whole size of this transfer. Target should drop this transfer and acknowledge Initiator with error when received size is different to this value.
NT Command: Printer can establish connection through NT command in following format. Initiator Request: Opcode Transfer size Data Checksum Value 0x3000 Size NT command Reserved Size (Byte) 2 3 <16M 2 Opcode Transfer size Data Checksum Value 0x3000 Size NT response Reserved Size (Byte) 2 3 <16M 2 Target Response: Network Command Set: Printer can establish connection through commands below.
