PARC Model 303A SMDE
The jumper on the back panel board (Figure 2-6) must be in the disconnected
position for the PARC 303A. The BAS 100B/W can be used to control the
stirring, purging, knock and dispense of the PARC 303A SMDE. Two
connections are required (Figure 2-6):
To CELL STAND
Connector on 100B
To CELL
Connector on 100B
Figure 2-6. PARC cell connections.
1. Connect the CELL STAND port on the rear panel of the Electrochemical
Analyzer to the INPUT port on the rear panel of the 303A via a 25 pin ribbon
cable (P/N EF-1600). Line 22 of this cable must be disconnected for proper
operation of the 303A. Early versions of the BAS 100A require line 22 to be
cut. Later versions of the BAS100A and BAS 100B have a jumper on the
back panel board to disconnect line 22. However, line 22 is connected on the
BAS 100B/W, so the position of the jumper must be switched in order for the
knock function of the 303A to operate,
2. Use the Analog Signal Cable (P/N EW-8096) to connect CELL on the rear
panel of the Electrochemical Analyzer to the ELECTRODE TEST POINTS
on the rear of the 303A. The pins on the end of the cable are inserted into the
mounted sockets. The color code is:
Black pin into the WORK Electrode Socket
Red pin into the CNTR Electrode Socket
