Product Information System Unit Rear Panel Connectors an external transceiver. The workstation automatically selects the correct network setting. RS-232 Serial Input/Output Connectors There are a variety of peripheral devices that can attach to the RS-232 Serial Input/Output (SIO) ports on this workstation. Refer to the label on the rear of the workstation to locate serial port 1 and serial port 2. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation that accompanies each peripheral device for specific information concerning its use. The SIO ports are programmable, allowing functions such as bit rate, character length, parity, and stop bits to be set using the System Administration Manager (SAM) or by selecting a system special device file with the functions already programmed. The SIO Ports are used as interfaces for serial asynchronous devices to the CPU. Table 1-4. shows the SIO connector pin listings. The serial connectors are 9-pin D-sub connectors. Signal names are those specified in the EIA RS-232 standard. Table 1-4.

Use the SCSI connectors to connect external SCSI devices such as DDS-format tape drives and CD-ROM drives. Consult the documentation that accompanies each SCSI device for specific information concerning its use. Refer to Appendix B, SCSI Connections, for information about connecting SCSI devices to your workstation. NOTE There must ALWAYS be a terminator at both ends of a SCSI bus. This means one internal terminator and one external terminator. 28 Chapter 1

an external transceiver. The workstation automatically selects the correct network setting.
RS-232 Serial Input/Output Connectors
There
are
a
variety
of
peripheral
devices
that
can
attach
to
the
RS-232
Serial
Input/Output (SIO) ports on this workstation. Refer to the label on the rear of the
workstation to locate serial port 1 and serial port 2. Peripheral devices include printers,
plotters,
modems,
and
scanners.
Consult
the
documentation
that
accompanies
each
peripheral device for specific information concerning its use.
The SIO ports are programmable, allowing functions such as bit rate, character length,
parity, and stop bits to be set using the System Administration Manager (SAM) or by
selecting a system special device file with the functions already programmed. The SIO
Ports are used as interfaces for serial asynchronous devices to the CPU.
Table 1-4. shows the SIO connector pin listings. The serial connectors are 9-pin D-sub
connectors. Signal names are those specified in the EIA RS-232 standard.
SCSI Connectors
The
B1000/C3000
workstations
have
built
in
SCSI
connectors
for
Ultra2
Wide
Low-Voltage Differential (LVD) SCSI and Ultra Narrow Single-Ended (NSE) SCSI. Use
the SCSI connectors to connect external SCSI devices such as DDS-format tape drives and
CD-ROM drives. Consult the documentation that accompanies each SCSI device for
specific information concerning its use. Refer to Appendix B, SCSI Connections, for
information about connecting SCSI devices to your workstation.
NOTE
There must ALWAYS be a terminator at both ends of a SCSI bus. This means
one internal terminator and one external terminator.
