Page 36 of 56 BlueCoreTM01 Title PCM EXTERNAL LOOPBACK Summary Sets the PCM into external LOOPBACK mode, whereby the data written to the PCM output is read again on the input pin. A check is made that the data read back is the same (up to usual codec transformations) as that written. The LOOP BACK consists of 512 bytes of random data. The PCM port mode is selectable as PCM Mode (pcm_mode), which is the same as for PCM LB (radiotest_pcm_loop_back) The external LOOP BACK may be a simple wire. Related Test Spec Name None Note On the Casira under test, set CN8 jumper to Codec BYP and on header CN12 link pins 10 and 11. Test Arguments PCM Mode = 0 to 2 (default = 1) Return Data None Exit Click on Reset Chip. PCM EXT LB Example Display

BlueTest Instruction Manual bc01-an-047b © Copyright CSR 2001 This material is subject to CSR’s non-disclosure agreement. Page 51 of 56 BlueCoreTM01 Appendix 2 Known Software Issue(s) in BlueTest Version 1.4 (a) Pressing the Reset Chip button on the GUI while data is being transmitted sends a hardware reset command to the chip and restarts the serial stack software. Closing the GUI sends a hardware reset command to the chip. If the link fails, the connection can only be recreated by manually resetting the chip (power off/on) and by clicking on Reset Chip or closing down and restarting the GUI (both of which will restart the serial stack software). The above will not occur if no data is visibly scrolling in the window. The tests concerned are: g VCOTRIM g BUILD LUT g READ g LUT (b) There is a race between command responses indicating that a test has started and the first data relating to that test. This does not affect the test results. (c) It is not possible to rouse the chip from Deep Sleep except by powering down the chip and restarting.

Changes or modifications to the transmitter not expressively approved by CSR could void the authority ability to operate the equipment. User Label Warning !The transmitter is in compliance with the Part 15 FCC Rules. A label which demonstrates compliance with the FCC is located on the bottom of the laptop. The label contains the following information :- Contains FCC ID:- PIW632500516610 This label ID is to be used only for Dell lap tops. The use of this transmitter outside Dell laptops is illegal. Transmitter Warning ! Installers of the Bluetooth transmitter should note that the Bluetooth transmitter should not be co-located with any other transmitter, for example WLAN interfaces in the lap top.The distance between the Bluetooth transmitter and antennas of other radio equipment must be at least 20cm in distance away from each other. Any closer installations require additional certification filings to examine co-location issues.
