5.6 REVERTING TO FACTORY SETTINGS
5.6.1 Factory Network Settings
The 8099 can be reset to the default network settings listed in Table 1-3 at any
time by holding the LAN Reset Button in for 5 seconds while applying power
to the board. The TALK, LSTN and SRQ LEDs all blink on momentarily when
the board is changed back to its default settings. The Digital I/O configuration
values are not affected by the LAN Reset operation.
5.6.2 Factory Digital I/O Configuration
The 8099's Digital IO configuration can be reset to the factory settings listed in
Table 1-3 by sending the unit the CAL:DEFAULT command or with an internal
jumper as directed below. The CAL:DEFAULT command resets the current
values in RAM and saves them to the 8099's Flash memory. CAL:DEFAULT
does not change the network settings.
1. Turn the unit off and disconnect all cables.
2. Touch your hands to the shiny metal part of the computer or to some other
instrument that is grounded to the AC power lines and to earth.
3. Remove the PC assembly from its case by undoing the two rear panel
screws and the two screws on the bottom of the case. Press the Power
Switch to slide the PC assembly out of the case.
4. Locate the W1 (DEF) jumper pins as shown in Figures 2-9 or 2-10.
Use a jumper or clip lead to short the two W1 (DEF) pins.
5. Apply power to the board. Keep the until the DEF pins shorted while
he board boots up. This will take approximately 10 seconds. The
TALK, LSTN and SRQ LEDs will blink for 0.5 seconds as the default
configuration is saved in the flash memory. Repeat step 4 if you do
not see the TALK, LSTN and SRQ LEDs blink.
6. Power the unit off. Remove the W1 jumper.
7. To reassemble the unit, slide the PC assembly back into its case and
carefully guide the Power Switch through the front panel overlay.
Replace the screws. Do not over-tighten the rear panel screws.
5. Power cycle the unit and verify the network settings.
