B.3 SOLDER LINK AREAS
A number of functions can be configured with solder links on the TP400 board. The
board layout is so dense we have implemented these configuration options with
solder links that take less space than jumpers, as well as being more reliable.
Care must be taken when changing these link areas so that no accidental shorts are
produced or created. Default settings are noted below.
Two versions of the TP400 have been shipped. The Rev B board has two additional
solder links.
The board revision can be determined by locating the DSP Design document number
that appears at various places on the copper and silk screen ident of the TP400. The
number 158001.A00 or 158101.A00 identifies a Rev .A00 board. The number
158001.B00 or 158101.B00 identifies a Rev .B00 board.
LK1 - LK4 Not Present
LK1 – LK4 are not present on the TP400.
LK5 PME# Connection
The PCI specification has been extended to include a new signal, PME# (power
management event). This signal is not defined on the PC/104-Plus specification. DSP
Design have proposed that a previously reserved pin on the PC/104-Plus connector
be allocated to this new signal. The pin we recommend is pin C30. In case this pin
should be need to be used for a different purpose we have provided a solder link to
allow this pin to be disconnected from the TP400's PME# signal.
Pin C30 is PME#: Fit link (default)
Pin C30 is not connected: Omit link.
LK6 VREF or Microphone
This link determines whether Connector J6 pin 1 is used for the analog to digital
convertor VREF input or output, or the audio codec microphone input. See also LK14.
Pin 1 is A/D convertor VREF: Fit link
Pin 1 is audio codec microphone input: Omit link (default)
LK7 ADC0 or LINE_IN_R
This link determines whether Connector J6 pin 2 is used for the analog to digital
convertor channel 0 input, or the audio codec Line In Right input.
Pin 2 is A/D convertor ADC0: Fit link
Pin 2 is audio codec Line In Right input: Omit link (default)
