1. Start Observer.

2. Open the Packet Capture window by selecting

Capture > Packet Capture. This

view shows you whether or not all the packets have been captured, how full the

capture buffer is at any given time, and whether any low-level communication errors

have occurred (depending on the NIC).

3. Check, and if necessary, alter the setups (i.e., pre-filter, buffer size) by clicking on the

ETUP icon.

4. To begin the capture, select

Mode Commands > Start Mode or click on the START

icon

5. As soon as you have acquired a sufficient number of captures, select Mode

Commands > Stop

or click on the STOP icon to stop the capture process.

If the IP addresses of the communication partners are unknown or if you want to derive

them automatically from a TCP packet:

1. Change to the Observer Standard Decode view in

Mode Commands > View or click

on the V

IEW icon.

2. Mark a TCP packet belonging to the communication you want to decode.

3. Select

Mode Commands > Automatic DICOM Address Pair Setup to set the

addresses and ports of the communication partners for the DICOM post-filter

automatically.

4. Click on the O

K button.

5. You can now change to the DICOM window with

Mode Commands > Start

DICOM Decode

or click on the DECODE icon.

If the IP addresses are known:

1. Select Mode Commands > Start DICOM Decode.
