REFERENCE

RS-232C Connectivity

BACKGROUND

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.

ACTION

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.

METHOD

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

All network commands are available for use. (See Operation Manual p.55

COMMANDS

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.
