Step 4. Connect the Cables
The cables should be connected in the following order to ensure proper
connection:
1.
Connect the parallel cable to the GPIB-PRL and close the bail-lock clips.
Connect the other end of the cable to your parallel device. Be sure to use
only shielded parallel cable.
2.
Connect the GPIB cable to the GPIB-PRL and tighten the thumb screws
on the connector. Connect the other end to your GPIB system. Be sure
to obey all IEEE 488 cabling restrictions, and use shielded GPIB cable.
3.
Connect the power jack of the wall-mount power supply to the power
receptacle on the back panel of the GPIB-PRL, then plug the supply into
an AC outlet of the correct voltage.
Note:
To disconnect the cables, remove the GPIB cable before removing
the parallel cable so that the bail-lock clips can be unlocked.
Step 5. Power on the Unit
Power on your GPIB-PRL by using the front panel rocker switch. The
POWER LED should come on immediately and the READY indicator should
come on after the GPIB-PRL has passed its power-on self-test indicating the
unit is ready for operation.
If the READY indicator does not come on within seven seconds after the unit
is powered on, recheck all connections and switch settings and retry the
power-on sequence. If the READY light still fails to come on, contact
National Instruments.
Operation
The GPIB-PRL is now ready to operate. All characters sent to the unit will be
received at full speed and stored in the internal data buffer. The characters
will be sent to the receiving device at the rate of the receiving device.
If using the GPIB-PRL in P mode, turn on the GPIB instrument before turning
on the GPIB-PRL and be sure the configuration switches are set correctly.
Simply send data to your parallel port as you would if you had a parallel
device connected to it and the data will be converted and sent to the GPIB
instrument. If you are using a standard software package, such as a word
