STEP 1:
Connecting the analog signal cable:
NOTE: The analog output fromsomeGCs or LCs can have a range of up to
10 volts dc. Although theModel 203will allowhigh voltage inputs such as this;
be advised that signals above 6 voltswill generate unwanted noise and signals
above 5 voltswill be "clipped". (The tops of thewaveforms will be cut off.)
Route the analog signal cable fromyour instrument through the open hole in the
back of the Model 203.
Strip 1/4" of insulationoff of the 'signal
+'
and 'signal-' wires of your signal cable.
Insert 'signal

and
secure theconnection using a small screwdriver.
Insert 'signal -' into the Lawson203 board screw terminal marked 'sig -' and
secure theconnection usinga small screwdriver.
STEP 2:
(OPTIONAL) Connecting the remote start cable:
NOTE: TheModel 203 offers a remote starting capability as a standard
feature. This permits the user to start the data systembymeans of a
switch closure, such as a footswitch. In some applications, the
chromatograph being usedwith theModel 203 may offer a remote
start signal output or switch closure output that permits starting an
integrator or other devicewhen theSTART button is pressed on the
chromatograph's on-board control panel. Typically, this signal can be
used to start theModel 203.
Route the remote start cable fromyour instrument through the open hole
in the back of theModel 203.
Strip 1/4" of insulation off of the
'+'
and '-' wires of your remote start cable.
Insert
'+'
into the 203RLYboard screw terminal marked 'IN' and secure the
connectionusinga smallscrewdriver.
Insert ' -' into the 203RLYboard screw terminal marked 'GND' and secure
the connectionusing a small screwdriver.
NOTE: Be sure to check the "RemoteStart" box in the PeakSimple For
Windows EDIT - CHANNELS - DETAILSscreen for channel 1.
Refer to the "PeakSimpIeForWindows" section of this manual.
STEP 3:
(OPTIONAL) Connecting the external event relay wires:
TheModel 203 features eight 0-5 volt TIL Level outputs that may be turned on
and off individually and automatically bymeans of a timed event table.
Manual control is also availablevia the keyboard.
These outputs may be used to control external events or devices. If TIL level
outputs are not adequate for your application, theModel 203 can be fittedwith
eight relay circuits offering normally open (NO) and normally closed (NC) contact
closures. NOTE: Relay contact closuresmust be specifically requested at the
time you order theModel 203.
