Chapter 2. Setting Up the Express 3000
61203153L2-20 Express 3000 User Manual 2-9
Setting the DIP Switches
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
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.

DIP Switch 1
With DIP switch 1 set to the
ON (down)
position, the Express 3000 auto-
matically 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 operate
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:
(DTE Rates)
On (Down) = Autobaud (speeds up to 115.2 kbps)
Off (Up) = 230.4 kbps (requires 16650 UART)
DIP Switch 2:
(Reset)
Off (Up) = Factory Default (resets settings)
On (Down) = Normal (saves settings)
