Connecting To Sun Workstations; Sgi Workstations With Irix 6.2 Or Higher - Logitech LogiCad3D Magellan/SPACE MOUSE Classic User Manual

output voltage of the SGI port handshake
signals to 5 V and 10 mA to supply the
Magellan/SPACE MOUSE. The input handshake
signals CTS and DCD of the workstation are
not connected in order to save some current
taken from the workstation's output handshake
signals DTR and RTS.
Different SGI workstations—despite somewhat
similar connector types—show different
voltage and current conditions at the serial
RS232 port. One example is a Personal IRIX
workstation, which offers such a low current
(and voltage) handshake signal that the
Magellan/SPACE MOUSE (as well as any
standard mouse) is not able to operate due to
a lack of current. In such cases, only an
external power supply (min. 5.0 V, max. 11.0
V, 9 mA DC) into the DTR pin of the Magellan/
SPACE MOUSE will solve the problem. An
appropriate adapter cable with external power
supply has been included in the product
package based on the system specified at the
time of order. However, if an adapter with the
external power supply feature has not been
included with your Magellan/SPACE MOUSE or
should you discover after ordering that your
SGI machine requires an external power
supply, please contact the
Center listed for your area.

Connecting to SUN Workstations

To install the Magellan/SPACE MOUSE on SUN
workstations, make sure that the hardware
configuration of the serial port to which you
want to connect the Magellan/SPACE MOUSE is
set to RS232. The default is RS422! The RS232
configuration is required in order to supply
control voltages to the Magellan/SPACE
MOUSE through the handshake signal lines. To
configure the port to RS232, follow the steps
in your SUN user handbook. The wiring
scheme of the SUN–Magellan/SPACE MOUSE
adapter is shown below.

SGI Workstations With IRIX 6.2 or
Higher
Some applications support the driver for the
Magellan/SPACE MOUSE that is integrated in
SGI systems with IRIX version 6.2 or higher.
At present, the following applications support
this driver:
Alias
Open Inventor
Follow the procedure below to install the X-
Window driver with these applications.
1 Login as root and launch the inst
program.
2 Select the CD-ROM as the source drive
(the Magellan/SPACE MOUSE driver is
located on the IRIX 6.2 System CD-ROM
1 of 2).
3 Select the step installation menu with
the following commands:
inst
install eoe.sw.optinput
go
quit
4 Exit the inst program.
5 Using the System Manager Tools,
configure the Serial Port Setup to which
the Magellan/SPACE MOUSE is connected
(Port 2) as Magellan . Test the installation
with Run Confidence Test .
6 For older applications that use the old
name (e.g. IRIX Inventor) you must
create the file /usr/lib/X11/input/
config/magellan with following contents:
x_init {
name "spaceball"
}
After creating the file, reboot the system
for the new configuration to take effect.
NOTE: Install either the xdriver or the IRIX
kernel driver. Do not install both! For older
R3000 workstations, please contact the
LogiCad3D Support
and ask if a driver is available. You can also
check our homepage at www.logicad3d.com.
