Page 9: Card Description
EDM 01-18 DAG 4.5G2/G4/GF Card User Guide Card The DAG 4.5 card provides two or four optical or copper Gigabit Ethernet interfaces. It is capable of full line rate (1,000Mbps) capture and transmission Description of Ethernet traffic and is protocol independent. Full packet capture at line rate allows recording of all header information and/or payload with a high precision timestamp.

Page 13 EDM04-10 Data Stream Management API Programming Guide and EDM04-07 dsm-loader User Guide available from the Support section of the Endace website at www.endace.com. Inline Forwarding The DAG 4.5 card supports inline forwarding which enables the card to receive and transmit packets directly from a single memory.
Page 15: Chapter 2: Installation
EDM 01-18 DAG 4.5G2/G4/GF Card User Guide Chapter 2: Installation Introduction The DAG 4.5 card can be installed in any free PCI-X slot. It operates at 66MHz, 100MHz or 133MHz PCI-X mode but will not operate in 32-bit or 64-bit PCI slots. Higher speed slots will achieve better performance. Although the DAG driver supports up to sixteen DAG cards in one system, the DAG card makes heavy use of PCI-X bus data transfer resources.
Page 16: Port Connectors
Setting Power The optical power range depends on the particular SFP module that is fitted to the DAG card. However Endace recommends you use the 1000baseSX 850nm short range modules which are shipped with the card. Optical power is measured in dBm. This is decibels relative to 1 mW where 10 dB is equivalent to a factor of 10 in power.

Page 31: Chapter 5: Synchronizing Clock Time
Common synchronization sources include GPS or CDMA (cellular telephone) time receivers. Endace also provides the TDS 2 Time Distribution Server modules and the TDS 6 units that enable you to connect multiple DAG cards to a single GPS or CDMA unit.
Page 32: Timestamps
EDM 01-17 DAG 4.5G2/G4/GF Card User Guide ERF files contains a hardware generated timestamp of each packet’s arrival. Timestamps The format of this timestamp is a single little-endian 64-bit fixed point number, representing the number of seconds since midnight on the January 1970.

Page 34: Building
The DAG time synchronization connector supports an RS-422 (PPS) signal from an external source. This is derived directly from an external reference source, or distributed through the Endace TDS 2 (Time Distribution Server) module which allows two DAG cards to use a single receiver. It is also possible for more than two cards to use a single receiver by “daisy-chaining”...
Page 35: Single Card No Reference
EDM 01-18 DAG 4.5G2/G4/GF Card User Guide Single Card No When a single card is used with no external reference, the card can be synchronized to the host PC clock. Most PC clocks are not very accurate by Reference themselves, but the DUCK drifts smoothly at the same rate as the PC clock. If a PC is running NTP to synchronize its own clock, then the DUCK clock is not as smooth because the PC clock is adjusted in small jumps.
Page 36 EDM 01-17 DAG 4.5G2/G4/GF Card User Guide Two Cards No Synchronizing with Each Other Reference Although the master card’s clock will drift against UTC, the cards will still be locked together. This is achieved by connecting the time synchronization (cont.) connectors of both cards using a standard RJ-45 Ethernet cross-over cable.

EDM 01-18 DAG 4.5G2/G4/GF Card User Guide Overview Connector Pin-outs DAG cards have an 8-pin RJ45 connector with two bi-directional RS422 differential circuits, A and B.
