AQUOS BOARD™ TECHNICAL BULLETIN August 11, 2014 Bulletin #14167 MODELS PN-L603A PN-L603B PN-L703A PN-L703B REFERENCE RS-232C Connectivity BACKGROUND ACTION METHOD The AQUOS BOARD™ models listed above do not provide an out of the box RS-232C port. This bulletin will explain how to utilize remote RS-232C control by utilizing the built-in service port connector. Users can purchase the 3rd party adapters listed below. When connected to the AQUOS BOARD™, these adapters will permit a standard RS-232C control cable to be connected to the unit. *Note, the gender changer may not be required depending on the cable used. The 3.5mm RS-232C port is located on the right side of the back of the display under a service cover. This cover is attached with a single screw and must be removed to access the port. PARTS REQUIRED DB9 Male to 3.5mm Male Adapter Cable 1.5 Feet DB9 Female/Female Mini Gender Changer SUPPORTED COMMANDS All network commands are available for use. (See Operation Manual p.55-p.62) LIMITATIONS Sharp is currently developing updated firmware to enhance the RS-232C capability, but currently the following limitations apply: - Baud rate Speed: Only 38,400bps is supported. - When an RS-232C command is sent, do not use LAN control and control via a web browser. - When controlling via RS-232C commands, please use the (default) standby mode. If the "low power mode" is used, RS-232C data may not be received. - When using RS-232C commands with the "A" models, commands cannot be received for approximately 3 minutes during the power up or shut down sequence whether initiated either via the IR remote, or front panel power button. - If the main power on switch on the back of the unit is cycled, you will need to clear the receiving buffer due to erroneous data.
