9.6 CONFIGURATION MENU
DTR units incorporate a configuration unit that can only be accessed through the relay keypad. Its objective is to
select how the DTR unit will interact with external elements.
The configuration unit is accessed from the stand-by screen, by entering a 4-character code through the unit keypad.
If the code is correct, the configuration unit is accessed; otherwise, we remain at the standby screen. The code is
unique for DTR relays, as it does not intend to be a password, but a security measure to avoid accidental
modification of the configuration. This code is 7169, which corresponds to the ASCII code of GE initials. Please refer
to the example below:

keys.
•
NET BAUDRATE : Is the baudrate used by the DTR in serial communications with the remote controller. The
possible baudrate range is 1200 to 19200 bauds.
•
NET STOP BITS : is the number of stop bits added to each byte transmitted via the serial line. This setting is
treated as a binary logic setting, selected by the logic key 1/Y for 1, and 3/N for 2.
•
LOC BAUDRATE : Is the baudrate used by the DTR in serial communications with the local controller. The
possible baudrate range is 1200 to 19200 bauds.
•
LOC STOP BITS : Same setting as in the remote case, but referred to local communications.
•
LOCAL SETTINGS : This setting enables/disables the setting change through local communications.
•
REMOTE SETTINGS : This setting enables/disables the setting change through remote communications.
•
LOCAL OPERATIONS : This setting enables/disables the feature of commanding operations locally.
•
REMOTE OPERATIONS : This setting enables/disables the feature of commanding operations remotely.
•
UNIT NUMBER : Each DTR is identified by a unit number, used for identifying messages addressed to each unit
when there are several units connected to the same communications line. This number can be any between 1 and
255, both inclusive.
•
PASSWORD : In order to avoid undesired communication with the relay through GE-LOCAL communications
software, DTR units incorporate a password. This password can only be seen from the relay display and is a
number between 0 and 99999. The password entered in GE-LOCAL must match the unit password for enabling
communication.
•
t TIMEOUT : Maximum external synchronization time for avoiding a timeout event.
