1 – RESET. Turn to ON and then to OFF again for Reset operation.
2 – OPER/LOAD. Operation in OFF and program loading via Port 1 in ON
position.
3 – Fixed port 1 parameters. If in ON position, the port 1 address is 1, speed
9600 b/s, no handshake
4 – Restore the DEFAULT setup. Turn switch 4 to ON, do a Reset with switch
1, turn switch 4 to OFF while the red LED is blinking, wait until green LED
starts to blink (do not do a Reset before that)
To enter into hardware test mode, switches 3 and 4 are simultaneously set
to ON position and then followed by Reset. An ordinary PC terminal program
is used for that. PC is connected to port 1.

Yellow LED – RX
Green LED – TX
Green LED at SSP port – blinking indicates the existence of GPS time

9. Firmware Update
Loading GW5 firmware from a PC computer is done through port 1. Switch 2
has to be set to ON position, followed by Reset. Firmware loader SDFlash.exe
can be found on the GW5 configuration CD. Firmware code is stored in the
gw5.out file.
Firmware update from CD
1. Set the GW5 switch ”Firmware update mode“ to “On“ position
2. Reset with the “Reset” switch (do not leave it ”On“)
3. Open ”GW5 Firmware Update“

If the gw5.out file is in the same catalogue as SDFlash.exe (the program
that you use for firmware update) then gw5.out is sufficient. However, if you
want to download firmware from some other place then you have to show
the exact way, for example, C:\GW5\ Firmware\…\gw5.out

•Invert – Object’s value will be inverted
•Fn.code – Function code on the IEC 60870-5-103 protocol
•Info no. – Information number on the IEC 60870-5-103 protocol
•Index – Object index on the IEC 60870-5-103 protocol. It indicates the
order number of the object in message types 3 and 9 of analog
measurements.
•Object.Addr ν– Object’s downlink address
•Object.Addr ^ – Object’s uplink address
•DB – Deadband (% of full scale). If the value has changed less than
the deadband then it is not spontaneously transferred.
•DB2 – This is used instead of DB if the Crit.Min and Crit.Max fields
are used and the value falls within these limits. In case of offline
(GSM) channel, if the change in value is bigger than deadband 2 (% of
full scale) then a call to SCADA system is initiated. Raw Min, Raw Max
– Minimum and maximum raw values of analog measurement (before
scaling).
•Scale Min, Scale Max – Minimum and maximum scale values of
analog measurement.
•Crit.Min, Crit.Max - minimum and maximum values in % from the full
scale of analog measurements on which GW5 initializes
communication (Fig. 10.5.1). If Crit. Max and Crit. Min do not have
values, DB1 and DB2 are in use. If Crit. Max and Crit. Min have the
value ‘zero’, only DeadB1 is in use. If the analog measurement value is
between Crit. Min and Crit. Max, DB2 is in use. If the analog
measurement value is out of limits, DB1 is in use.
•Forb. Ports – Uplink port to which the object’s value transfer is
blocked. To select uplink ports, which should not be used for
transferring these object values, double-click on the cell of the Forb.
Ports column and select the corresponding ports from the window that
has appeared.
