OK response

After processing of each command is completed, a response is sent indicating that the next command can be received.

BUSY response

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

<BUSY response character string>:=i:BUSY

Example:

> IMAGE=2 < i:BUSY

WARN response This response is sent when warning information is issued.　Note that this command cannot be executed.

> IMAGE=2

Example:

< w:USER_COMMAND_VERSION_IS_UPDATED

ERR response An error message is output.

※　<Error code> is expressed as a four-digit hexadecimal number. * Refer to “Error List”!

3.Communication Flow

Transmission

sent

Transmission

received

Command/ One response is always returned for each command sent from the PC.

Response

reception

timeout

At the sending side (PC), the transmission is sent within character intervals of Tc (character interval timeout).

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.

(However, note that a response may not be returned when the internal receive buffer overflows due to reception of a large amount of data.)

PC SX50

Command

Within Tr

Response

*The timeout interval between command and response (Tr) is 10 seconds.

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”.
