8. KEYBOARD AND DISPLAY
8.6. CONFIGURATION MENU.
The DBF has a configuration unit which can only be accessed by means of the keyboard.
To enter the configuration, start from the main screen ‘DBF – GENERAL ELECTRIC ’ and use the keyboard to enter a
The code is unique for all the DBF relays and is not intended to be a password, but rather a simple safety measure to avoid accidental changes to the configuration. This code is 7169, chosen to coincide with the ASCII code for the initials GE.
After pressing 7169 at the front keyboard, and scrolling with the arrow keys, the following information will appear:
•NET. BAUDRATE : The speed in bauds which the DBF will use for serial communications through the remote port. The possible speeds are between 1200 and 19200 bauds.
•NET.STOP BITS : The number of stop bits which are added to each byte which is transmitted on the serial line. It is treated as a binary logic setting selected by means of the logic key 1/Y for 1 and 3/N for 2.
•LOC. BAUDRATE : as above but for local communications.
•LOC. STOP BITS : As above but for local communications.
•LOCAL SETTINGS : Settings changes by local communications (allowed/not allowed).
•REM SETTINGS : Settings changes by remote communications (allowed/not allowed).
•LOC OPERATIONS : Operations being performed by local communications (computer directly connected) (allowed/not allowed).
•REM OPERATIONS : Operations being performed by remote communications (e.g. modem) (allowed/not allowed).
•UNIT NUMBER : Each DBF is identified by a unit number which it uses to identify the messages which are sent to it on the remote communications line. This number can be between 1 and 255.
•PASSWORD : To prevent unauthorized persons from communicating with the relay via a communications program and changing the settings or performing operations, the relay has a password. This password can only be seen on the relay display and takes the form of a number between 0 and 99999.
