Setting the DIP Switches

The Express 3000 SP 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

down (ON)

. Leave the switches in the

down (ON)

position during the

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

Rear Panel.

Figure 2-3. DIP Switch Locations on Rear Panel

DIP Switch 1

With DIP switch 1 set to the

ON (down)

position, the Express 3000 SP au-

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

set to the

OFF (up)

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 oper-

ate at this higher rate.

DIP Switch 2

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

OFF (up)

position. When the switch is set to the

ON (down)

position,

new settings can be entered. These settings are saved until DIP

switch 2 is reset to the

OFF (up)

position; then, they are cleared.

DIP Switch 1:

On (Down) = Autobaud (speeds up to 115.2 kbps)

Off (Up) = 230.4 kbps (requires 16650 UART)

DIP Switch 2:

Off (Up) = Factory Default (resets settings)

On (Down) = Normal (saves settings)
