DX404/DX504/DX604 User’s Guide & Operating Manual
Appendix B – Remote Programming Option
The DX404/DX504/DX604 can be remotely programmed via a:
• RS232C interface
The data rate is set for 9600 Baud, 8 bits, no parity, 1 stop bit and no
handshaking signals.
B.1 Enabling the remote programming option.
On receipt of a valid command on the serial port, the DX604 enters
the ‘Remote/Programming’ mode and the front panel keypad is
‘locked’. The second line of the front panel LCD will display as
follows:
The P indicating the ‘Remote or Programming’ mode and the L
indicating the locked keypad. To bring the unit back to front panel
operation, the unlock command (*055) can be sent on the serial bus
or use the front panel keypad.
B.2 Commands and responses
Commands sent to the DX604 should be terminated by the “carriage
return” (0Dh) character, the “line feed” (0Ah) character, or the
“carriage return” + “line feed” sequence.
If the command sent is valid, it will be executed and the new content
of the LCD display is sent to the RS232C or IRDT interface,
terminated by a carriage return + line feed. If the command is not
valid, the sequence ‘Error’ is sent back.
Note: When ID is set, prefix all serial commands with the three-byte
EIN sequence. Refer page 16
