These specifications describe the methods of controlling the SX50 projector from the PC over an RS-232C connection.
Virtually all operations possible with the remote control can be controlled from the PC.
The following symbols are used in these specifications.

separator
□Space with 1 or more characters (20h), Tab (09h), or other
separator

BUSY
BUSY response
This response is sent when a command cannot be received during processing.

Cable
The connection diagram for the cable connecting the PC and projector is shown below.

3.Communication Flow
Transmission
sent At the sending side (PC), the transmission is sent within character intervals of Tc (character interval timeout).
Transmission
received
A
t the receiving side (SX50), data able to be received within the character interval of Tc is held, and receiving of a delimiter is considered
“transmission received”.
If a received character interval exceeds Tc or a delimiter is not received within 256 characters, all data already received is
lost, and the mode is reset to receive standby again.
Command/ One response is always returned for each command sent from the PC.
Response (However, note that a response may not be returned when the internal receive buffer overflows due to
reception of a large amount of data.)

timeout
If a response is not received within Tr (timeout interval between command and response) while in response reception standby
after sending a command at the PC, resend the command in the “response reception timeout”.
