5.1 Promi-SD202

Promi-SD202 (part no. PSD00-20200), released from June 1, 2003, and will include

the following upgraded features:

1) Promi-SD202 will include Class 1 Bluetooth chip, default distance: 100m;

maximum distance, via Patch antenna: 1.2Km.

2) Automatic Hardware flow control setting

3) Promi-SD202 uses Pin 1 (CD) to display Bluetooth connection status.

Pin 1 is ON if connection is active, Pin 1 is OFF if non-active.

4) Host system can automatically indicate Promi-SD202 operation status, by Pin 4

(DTR) and Pin 6 (DSR) instead of by AT commands, as Promi-SD202 loops

back status data to Host. When Host turns on DTR signal, Promi-SD202

returns Active DSR signal to Host indicating Active operation status.

AT commands may also be used for operation status check.

5) Using Pin 4 (DTR) signal, Host may disconnect Bluetooth connections, without

AT commands. When Host changes the DTR signal to Non-active, Promi-

SD202 will drop the connection. AT commands may also be used for

disconnect.

Full specification of Promi-SD202 will be released soon.
