Finally, you terminate the last device on each chain, leaving the adapter unterminated. 25: Cabling internal and external SCSI devices together Note Even though the third technique described is the technically correct way to install termination for the hybrid situation (in which you have both internal and external devices), some adapter cards still need to have terminators installed. Each device must also have a unique SCSI ID number. This number can be assigned by the jumper (with internal devices) or with a rotary switch (on external devices).
The wires are soldered to modular connectors at both ends. These connectors allow the cables to be quickly attached to the devices they connect. Cables may be either shielded or unshielded. This refers to shielding against electromagnetic interference (EMI); it has nothing to do with whether the cable is shielded against dirt or water. 5. The F or M in a connector’s designation is for Female (holes) or Male (pins). 5: Common PC Cable Descriptions Application Null modem Null modem RS-232 (modem cable) RS-232 (modem cable) Parallel printer External SCSI cable 1st Connector DB-9F DB-25F DB-9F DB-25F DB-25M Centronics 50M 2nd Connector DB-9F DB-25F DB-25M DB-25M Centronics 36M Centronics 50M VGA extension cable UTP Ethernet cable Thinnet Ethernet cable Telephone wall cable DB-15M RJ-45M BNC-M RJ-11M or RJ-14M DB-15M RJ-45M BNC-M RJ-11M or RJ-14M Max.
