3.1.5 Restoring Default IP Address, Subnet Mask, Gateway Address
In the event that the IP address of an Adapter is unknown, its communications settings
can be restored to factory default values by following the procedure below:
Figure 14: Pin numbering and LED locations.
1.
Disconnect the Adapter from the network.
Attention: Determine how your
control system will respond before disconnecting an Adapter from the
network.
2.
Detach the Adapter from the DataStick.
3.
Make an electrical connection between pins 5 and 9 on the DataStick-side of the
Adapter using a clip lead or equivalent as shown in Figure 14. Be careful to make
the connection only between pins 5 and 9.
4.
Apply power to the Adapter and watch the Heartbeat LED shown in Figure 14.
After approximately 5 seconds, the Heartbeat LED will blink red and green at a
rate of 2 Hz. This indicates that the Adapter has detected the connection between
pins 5 and 9 and restored the communications settings to their factory default
values.
5.
Disconnect the power from the Adapter and remove the electrical connection
between pins 5 and 9. Re-attach the Adapter to the DataStick.
6.
Establish communications with the Adapter as described in Section 4.
