applications in IBCL mode.
Step 4: Connect the Cables
Connect the cables as follows:
1. Connect the serial cable to the GPIB-232CT and securely fasten the
holding screws. Connect the other end of the cable to your serial
device. Be sure to use only shielded serial cable, and obey all
RS-232 cabling restrictions.
2. Connect the GPIB cable to the GPIB-232CT 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 only double-
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-232CT, then plug the supply
into an AC outlet of the correct voltage.
Step 5: Power on the Unit
Power on your GPIB-232CT by using the front panel rocker switch. The
POWER
LED should come on immediately. The
READY
indicator
should come on after the GPIB-232CT 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 for further instructions.
