NetPerformer <strong>SDM</strong>-<strong>8400</strong> Hardware Installation Guide<br />
7.1 Serial Port<br />
4 or 8 serial ports for WAN/user traffic:<br />
• HD-26 female connector<br />
• Asynchronous speeds: 300 bps to 115.2 Kbps<br />
• Synchronous speeds: 1200 bps to 6 Mbps (6144 Kbps) without data compression;<br />
896 Kbps link port maximum speed with data compression<br />
For further details concerning the serial port, turn to “WAN/User Port Specifications” on<br />
page 7-4.<br />
7.2 Custom HD-26 Cable<br />
The serial ports require a custom-made HD-26 male cable, which can be ordered from<br />
Memotec or your NetPerformer distributor. For ordering information, refer to “Sales<br />
Contacts” on page 1-2.<br />
The required cable depends on the interface and gender of the attached equipment. Twelve<br />
custom HD-26 serial cable models are available:<br />
• V.35/V.11 DCE, V.35/V.11 DTE (for details see “V.35/V.11 Cables” on page 7-5)<br />
• TIA-232 (V.24) DCE, TIA-232 (V.24) DTE (see “TIA-232 (V.24) Cables” on<br />
page 7-5)<br />
• X.21 DCE, X.21 DTE, with 4-40 screw on the DB-25 connector (see “X.21<br />
Cables” on page 7-5)<br />
• X.21 EU DCE, X.21 EU DTE, with metric M3 screw on the DB-15 connector<br />
(see “X.21 EU Cables” on page 7-6)<br />
• TIA-449 (V.36) DCE, TIA-449 (V.36) DTE (see “TIA-449 (V.36) Cables” on<br />
page 7-6)<br />
• TIA-530 DCE, TIA-530 DTE (see “TIA-530 Cables” on page 7-6).<br />
All cables are 1.8 meters (6 feet) long, and have HD-26 male connectors at one end. At the<br />
other end:<br />
• A male connector indicates that the cable is DTE and that it connects to a DCE<br />
device (a modem, for example).<br />
• A female connector indicates that the cable is DCE and that it connects to a DTE<br />
device (a terminal or another NetPerformer, for example).<br />
NOTE: When ordering a cable for the serial port, make sure you specify the correct<br />
gender.<br />
