Reception Error The response command differs between the reception error and parameter error. • Communication error (Reception error) When the unit cannot properly receive the command due to the communication error, the unit immediately sends back the NACK code to the PC. After clearing the receive buffer, the unit enters the wait state until receiving the following [STX] command. [NCK] N = Reception failed (ASCII code: 15H) Reason for the communication error 1: Parity error (ASCII code: 31H) 2: Framing error (ASCII code: 33H) 3: Overrun error (ASCII code: 34H) • Parameter error When the unit cannot properly process the received command, the unit sends back an error code to the PC. After clearing the receive buffer, the unit enters the wait state until receiving the following [STX] command. ER N [ETX] =Error Reason for the error 001: Command invalid (There is no associated command.) 002: Parameter invalid (The number, digit, or range of the command parameters is incorrect.) 301: Command invalid (The unit does not support the operation mode.) E: Command error (ASCII code: 45H) • If the unit receives another command during the response, the unit will respond to the command after processing the current response. • If the unit received the [STX] command again before receiving the [ETX] command, the unit will clear the internal buffer. Then, the unit will process the data following to the [STX] command. (The commands received before the second [STX] command will be canceled.) • The internal buffer will be cleared when it fills up.* 155
