‚ Turn off the power to the System 1100.
‚ Open the front door of the System 1100
enclosure.

down the channel 1 and 2 dual channel card
(the card in the bottom of the unit that has the
channel 1 and channel 2 strain gauges plugged
into it ). Remove the channel card by pulling
on the handle on the card.
‚ Using Figure A.2, locate the software chip on

MB” in the socket for a two channel unit, or
the chip labeled “1100-4-MB” for a four
channel unit. A 4 channel chip in a 2 channel
motherboard or a 2 channel chip in a 4
channel motherboard will prevent the unit
from working correctly!

Be sure not to leave any lockwashers or
screws loose in the unit!
