3.0 CONFIGURATION
The Model 2530 features configuration capability via hardware
switches or a software control port. This section describes all possible
hardware and software switch configurations of the Model 2530.
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
The Model 2530 has 24 DIP switches that allow configuration to
wide range of applications. The 24 switches are grouped into three
eight-switch sets, and are externally accessible from the underside of
the Model 2530 (See Figure 1).
The three sets of DIP switches on the underside of the Model 2530
will be referred to as S1, S2, and S3. Figure 2 shows the orientation of
all DIP switches with respect to “ON” and “OFF” positions.

3.1.1 DIP Switch Set “S1”
The DIP switches on set S1 may be used to configure the DTE
rate, RTS/CTS delay, anti-stream timer, data format, character length
and Extended Signalling Rate (ESR) Default settings and detailed
descriptions for each switch in the set are shown below.
Switches S1-1, S1-2, and S1-3: DTE Rate
Use Switches S1-1 and S1-2 to configure the DTE rate of the
Model 2530. This rate represents the synchronous or asynchronous
rate at which the DTE must connect to Model 2530’s
QuikConnect™
interface.

Switch S1-4: RTS/CTS Delay
The RTS/CTS delay is the amount of time it takes for CTS to
change logic state following an RTS transition. Use Switch S1-4 to
select the RTS/CTS delay (measured in
msec.).
