Connection ports on the MAC

Connection ports
    What exactly are all those connection ports (SCSI, ADB, USB, RJ45, etc...) at the back of your Macintosh?

    For keyboard, mouse, trackball, drawing tablet, or joystick. Do not plug or unplug one of these attachments when your Mac is turned on.

    modem printer Modem or
    serial port
    For printer, modem, midi, or other devices ...

    Replaces the old modem and printer ports and ADBs on the newer MACs (since the iMAC). Plug and play (computer does not have to be turned off to plug or unplug devices).

    Ecran Apple Screen
    To plug in your Apple monitor. A VGA adapter is needed to plug in a PC monitor to this jack.

    SCSI External
    SCSI port
    For hard drives, removable storage devices, digital cameras, jaz, syquest, scanners, ....
    NEVER plug or unplug when the MACis turned on.
    Each peripheral must have a unique SCSI number: 1,2,4, 5 or 6 (the MAC is pre-assigned number 7, the internal disk the number 0 and the CD-ROM the number 3). If you have an internal SCSI drive separate from the external one or if your internal devices are configured with IDE you will have access to 0 and 3 for your external SCSI devices.
    The last device in your SCSI chain must be terminated (devices/peripherals are either self-terminating or have a switch that can be set to on or off).

    SCSI powerbook External
    SCSI port
    on Powerbook
    for hard drives, removable storage devices, digital cameras, jaz, syquest, scanners, ...
    and to connect to another MAC. Same comments as above.

    hard drives
    Most hard drives come with a 50 pin SCSI plug. You must therefore always use a "25/50" cable to connect to a MAC. Other peripherals are added to the SCSI chain using "50/50" cables. The quality of the these cables is the most important factor in the proper functioning of the peripherals, particularly when there are several of them.

    IEC m Firewire
    For hard drives, removable storage devices, digital cameras,jaz, scanners, .... and for connecting to another MAC.
    The main difference between firewire and SCSI connection ports are that firewire are "hot" connectable (computer can be turned on), there are no device numbers used, and they don't need to be terminated.

    IEC m Power cord
    For main power plug.

    IEC f Secondary
    Power plug for a monitor. Allows monitor to turn on as soon as your MAC boots up.

    Réseau AAUI
    for Network
    Used in conjunction with an adapter to allow connections with a network using RJ45 or BNC base.

    BNC BNC for
    10base2 networks
    To connect to a 10base2 network. All the connections are made in series with the use of a BNC adapter in a 'T' formation on a long coaxial cable with BNC terminators on both ends.

    RJ45 RJ45 for
    Network Plug to connect to a 10baseT or 100baseT network. All of the connections are made in a star shape out of a main hub.
