UNIGATE fieldbus gateway for Fast Ethernet V. 2.1
21.4.11
8.4.3
LED "Full Duplex"
This LED flashes when the data transmission is full duplex.
8.4.4
LED "10 MB"
This LED displays, that the data communication occurs on the Ethernet LAN with 10 Mbit.
8.4.5
LED "100 MB"
This LED displays, that the data communication occurs on the Ethernet LAN with 100 Mbit.
8.4.6
LED "Collision"
This LED indicates a collision of data in the Ethernet.
8.4.7
LED “Power“
This LED is connected directly to the (optionally also electrically isolated) supply voltage of the
RS485/RS232 end.
8.4.8
LED “State“
8.4.9
LEDs “Error No. / Select ID“ at UNIGATE SC-Fast Ethernet
If these 4 LEDs flash and LED “State“ simultaneously lights red, the error number is displayed in
binary notation (conversion table, see Annex) in accordance with the table in Chapter "Error han-
dling". Otherwise, the address with which communication is currently running via the RS485
interface is displayed, also in binary notation.
8.5
Switches
The gateway features 4 switches with the following functions:
Rotary coding switch S4
RS485 ID (High Byte)
Rotary coding switch S5
RS485 ID (Low Byte)
Slide switch “Interface“
Selector switch for RS485 or RS232 interface
Slide switch “Termination“
Switchable RS485 terminating resistor
8.5.1
Rotary coding switches S4 + S5 (RS485 ID)
These two switches are used to set the RS485 ID of the gateway in hexadecimal notation pro-
vided an ID is required for the bus. Please refer to the Annex for a conversion table from decimal
to hexadecimal. This value is read in only once when the gateway is activated.
8.5.2
Slide switch (RS485/RS232 interface)
This slide switch is used to select whether an RS485 interface or an RS232 interface is con-
nected at the connector to the external device.
