The development board connects the BT900 module to a virtual COM port of a PC or other device. From a PC, you
can communicate with the module using Laird’s UW Terminal application (version 6.51 or newer).
UW Terminal is a terminal emulation application capable of running on Windows 98, ME, 2000, XP, Windows 7, and
Windows 8 operating systems. It was developed specifically to aid development and testing of Laird modules. It
allows connection to serial devices using any combination of the communications parameters listed in
Table 5-1: Communication Parameters
COM Port:
1 to 255
Baud rate:
1200 to 921,600
Note: Baud rate default is 115200.
Parity:
None, Odd, Even
Data Bits:
8
Stop Bits:
1 or 2
Handshaking:
None or CTS/RTS
Note: Baud rates higher than 115200 depend on the COM port capabilities of the host PC and may require an
external USB – RS232 adapter or PCMCIA card.
The benefits of using UW Terminal include:
Continually displayed status of DSR, CTS, DCD, and RI
Direct control of DTR on the host PC via a check box
Direct control of RTS, if CTS / RTS Handshaking is disabled when UWTerminal is launched
Sending of BREAK signals
BASIC tab provides standalone testing and development of
smart
BASIC ** applications and allows
UWTerminal operation to be automated.
The BASIC embedded into UWTerminal, since version 6.20, shares the same core functionality as the BT900
series module.
Additional built-in features (right click in Terminal tab screen) to accelerate development including Automation
and various XCompile / Load / Run options for downloading
smart
BASIC applications into the BT900.
Note: Full details on
smart
BASIC are available in the
smart
BASIC User Manual available for download at the
Laird website. This document also includes a basic introduction to the UW terminal program.
Tip:
If the module returns a four hex digit error code: In UwTerminal, select those four digits, right-click, and
select Lookup Selected ErrorCode. A description of the error is printed on screen.
