4 Using the Evaluation Software
4.1 Setting Register Values.
On both the Volatile and Non-Volatile pages, the registers are labeled by function. To set a register value,
select the value from the options available for that register and click the “Write” button. To perform a read
of that register, simply click the “Read” button. Descriptions of the register functions can be found in the
Wi.232DTS Users Manual.

4.2 Diagnostic Mode Commands
There are a special class of commands available through the evaluation software. These controls are
located on the “Volatile Registers” page as seen below.
located on the “Volatile Registers” page as seen below.
These commands place the module into special diagnostic modes that can be used to test the module’s
performance, or to activate the transmitter for RF testing purposes. It is important to note that once a
module executes a diagnostic command, it should be reset or have the power cycled to return to normal
operation.

4.2.1 Transceiver
Mode
This selects the modulation mode and power output of both the transmitter and receiver. The mode is not
set until “Set TX Diag” or “Set RX Diag” is pressed. If “Set RX Diag” is pressed, the power output value is
ignored.

4.2.2 Transmit
Diagnostic
Transmit Diagnostic consists of four radio buttons which select the transmit channel. Low, Mid and High
are quick reference buttons which can be used to select the lowest, the middle, or the highest channel.
Any specific channel can be selected by using the controls below the “Set TX Diag” button.

If a “…1010101010101…” bit pattern is received at the frequency and baud rate set up in the relevant
registers, the BER test will return the number and percent of bit errors. This information is displayed in
the panel below the “Set RX Diag” button. If no transmission is present, or the transmission is at the
wrong frequency or data rate, the module may enter an infinite loop waiting for the beginning of the data.
In this case, the module should be powered down and back up to return the module to its normal
operating mode.
