Chapter 2: SETUP 

 
 

The 232MSS2 is set up using an eight-position dipswitch. This 

dipswitch is used to set the communication format, port config- 
uration, smart switch/port combiner mode and to enable/disable the 
enhanced features. To change the settings on the switch, remove 
the power from the unit, and remove the screws (4) from the bottom 
of the 232MSS2. The dipswitch is located on the top of the PC board 
(side with LEDs) and is labeled “SW1.” The other dipswitch, labeled 
“SW2” is used to set the second character of the preamble. After the 
switches have been set to match your requirements, you can put the 
unit back together. NOTE: The end panel should be open end 
towards the bottom of the PC board and the smooth side goes 
toward the inside. Table 1 shows the settings for dipswitch “SW1”.
