Fig. 3.1 - Gateway front
Print-out button
If Gateway is connected to a terminal or a PC in terminal emulation (through the config connector - selections: 9600, 8, N, 1 ),
the print-out button displays the configuration-parameter list and the program version installed in the Gateway EPROM.
Reset button
Forces the Gateway reset, starting the reading procedure of the Gateway configuration and the complete inquiry procedure of
all the connected peripherals.
LED line (yellow)
It shows the power supply.
rx and tx LEDs (green)
Their persistent blinking signals a correct communication between the Gateway and the Carel peripherals.
alarm1 LED (red)
If activated, it signals an anomaly in the parameter initial configuration.
In this case, reset the Gateway. If the problem persists, it is necessary to riconfigure the Gateway with the issued program (see
Procedures for the starting configuration ).
alarm2 LED (red)
If blinking, it signals an error in the communication between the Gateway and one or more Carel peripherals.
The cause may reside in inconsistencies compared to what was envisaged by the configuration. That is to say the number of
the peripherals recognized from the Gateway is lower than the number of the configurated peripherals.
WARNING : the LED flashes at every start-up of the Gateway, as long as it acquires all the variables from the connected
peripherals. Therefore, before this the LED flashing is normal and doesn’t signal any anomaly, but it only indicates that the
variable acquisition procedure is in progress.
