STEP1: Connect theAnalogSignalCable(s)
1-1. Routetheanalogsignalcablesfromyourinstrument
through theopenhole in thebackof theModel202.
1-2. Strip1/4”of insulation from the “signal+” and
“signal-”wiresofyourinstrument’ssignalcables.
1-3. Remove the jumpersshown in theclose-
uppicture to the left. Insert the“signal+”wire
into the Lawson 202 board screw terminal
marked“CH1sig+”andsecure theconnection
withasmallflat-bladescrewdriver.
1-4. Insert the“signal-”wire into theLawson
202boardscrew terminalmarked“CH1sig -”
andsecure theconnection.
1-5. Repeat theconnectionofsignalcablesfor
channels 2, 3, and 4. Any unused channels
MUSThaveboth inputs jumpered toground.
