You can connect the RS-232 DB-9 evaluation board directly to the PC without an RS-232 pass through cable or
null modem.
Power Terminals for Evaluation Board
Inputs on J9 & J10 can be >5VDC and <12.0VDC. Worst case power draw for the entire evaluation board is
150ma when the Bluetooth radio/modem connection is established and transmitting. Power consumption is much
lower depending on parameter settings.
Hardware UART Communications Connections for Modules and Eval Board
Radio module TX UART → RX of the application Micro Controller Unit (MCU)
Radio module RX UART← TX of the application Micro Controller Unit (MCU)
Radio module RTS UART→ CTS of the application Micro Controller Unit (MCU)
Radio module CTS UART← RTS of the application Micro Controller Unit (MCU)
PCMIF (Audio)
The module supports 13 bits Linear CODEC interface and the module is configured as master mode of PCM I/F.
1) PCM_OUT, PCM_IN, PCM_CLK, and PCM_SYNC carry one of bi-directional channel of voice data using 13bits
PCM at 8ks/s.
2) PCM_SYNC is output and operates at a fixed clock frequency of 8kHz.
3) PCM_CLK is output and operates at a fixed clock frequency of 256kHz.
4) Reference PCM audio device is Motorola MC145483 13 bit linear CODEC or Windbond W681360R
(recommended for new designs)
