BDI IP Address	Enter the IP address for the BDI2000. Use the following format:
	xxx.xxx.xxx.xxx e.g.151.120.25.101
	Ask your network administrator for assigning an IP address to this
	BDI2000. Every BDI2000 in your network needs a different IP address.
Subnet Mask	Enter the subnet mask of the network where the BDI is connected to.
	Use the following format: xxx.xxx.xxx.xxxe.g.255.255.255.0
	A subnet mask of 255.255.255.255 disables the gateway feature.
	Ask your network administrator for the correct subnet mask.
Default Gateway	Enter the IP address of the default gateway. Ask your network administra-
	tor for the correct gateway IP address. If the gateway feature is disabled,
	you may enter 255.255.255.255 or any other value..

Conﬁg - Host IP Address Enter the IP address of the host with the conﬁguration ﬁle. The conﬁgura- tion ﬁle is automatically read by the BDI2000 after every start-up.

Conﬁguration ﬁle	Enter the full path and name of the conﬁguration ﬁle.
	e.g. D:\ada\target\conﬁg\bdi\evs332.cnf
	For information about the syntax of the conﬁguration ﬁle see the bdiGDB
	User manual. This name is transmitted to the TFTP server when reading
	the conﬁguration ﬁle.
Transmit	Click on this button to store the conﬁguration in the BDI2000 ﬂash
	memory.

2.5.3 Recover procedure

In rare instances you may not be able to load the ﬁrmware in spite of a correctly connected BDI (error of the previous ﬁrmware in the ﬂash memory). Before carrying out the following procedure, check the possibilities in Appendix «Troubleshooting». In case you do not have any success with the tips there, do the following:

•Switch OFF the power supply for the BDI and open the unit as described in Appendix «Maintenance»

•Place the jumper in the «INIT MODE» position

•Connect the power cable or target cable if the BDI is powered from target system

•Switch ON the power supply for the BDI again and wait until the LED «MODE» blinks fast

•Turn the power supply OFF again

•Return the jumper to the «DEFAULT» position

INIT MODE

DEFAULT

• Reassemble the unit as described in Appendix «Maintenance»
