levels on the RS232 port conform to the RS232 standard and are generated on the

motherboard. It is also possible to connect to the BlueCore

01 UART using CMOS

(3V) levels using the second internal Molex connector on the 3V UART/Serial PCM

port. The USB port is type “B”.

USB Functionality.

First systems do not support USB. The first new BlueCore

radio module upgrade

will support USB. This is expected to be available in Q3 2000.

Note: When using USB the UART CTS and UART RTS pins are used for the

USB- and USB+ respectively. Hence it is not possible to use one unit with

both USB and RS232 connections operating simultaneously.

Eight LED’s are provided on each module and the function of each is as follows

LED 0 Radio RX ON LED 1 Radio TX ON

LED 2 ACL/LMP data received LED 3 ACL/LMP data transmitted

LED 4 SCO data received LED 5 SCO data transmitted
