The Express 3000 contains two DIP switches (1 and 2), located on the 
Rear Panel. These switches let you physically configure DTE rates and 
reset the unit. The factory default position for both switches is 

. Leave the switches in the 

 position during the 

initial installation. Figure 2-3 shows the location of the switches on the 
Rear Panel. 

With DIP switch 1 set to the 

 position, the Express 3000 auto-

matically adapts to the DTE rate, up to 115.2 kbps. With DIP switch 1 set 
to the 

 position, the unit operates at a DTE rate of 230.4 kbps. A 

special serial COM port using a 16650 UART chip is required to operate 
at this higher rate. 

DIP switch 2 resets factory default settings when you set it to the 

 position. When the switch is set to the 

position, 

new settings can be entered. These settings are saved until DIP 
switch 2 is reset to the 

 position; then, they are cleared.
