DESCRIPTION
UART
(Universal Asynchronous Receiver Transmitter)
串列埠適用於TI的DSK和EVM DSP開發平台並同時提供四個相容於DTE (Data
Terminal Equipment)和DCE (Data Communication
Equipment)的RS-232-C串列傳輸介面。並擁有適合UART的開發軟體。這些擴充卡適合用在TI
DSP
和
EVM
開發系統的
TI MS320
交會平台擴充卡上。

DIAGRAMS OF THE STANDARD RS-232-C
SERIAL COMMUNICATION PORT
DAUGHTER CARDS

 |
|
Above is a block diagram of the standard
RS-232-C Serial Communication Port cards
showing the location of each of the four
ports, (labelled "CHANNELS" on the
cards) the gender of the 9-pin, DB-9
connector, and the DTE/DCE
configuration. Each channel has a UART
driving the interface. Channels 1 and 2
are included in the 2-port cards and channels
1, 2, 3, and 4 are included in the 4-port
cards. Note that at the time of order,
the DTE/DCE configuration, and the interface
of any channel can be specified differently.
Note also that a DTE always has a male
connector and a DCE always has a female
connector.
Channel 2 is included in the 1-port card and
wired as a DTE with a male connector.
The hardware UART is removed allowing a
software UART to be used instead,

BLOCK DIAGRAMS
Block diagrams of each of the RS-232-C interface
cards are shown below.

Block diagram of the Model DSPG-IC-1-232, (no
hardware UART, software UART required), single
channel, RS-232-C Serial
Communication
This is the only card that does not have a
hardware UART. It is used when a
software UART is implemented in order to
minimize hardware in the final product.
This card has an RS-232-C interface wired as a
"DTE" (Data Terminal Equipment), and
a male 9-pin, DB-9 connector labeled "TO
DCE", unless specified otherwise at the
time of order. UART software is not
included but can be downloaded from the TI
website by clicking HERE.

Block diagram of the Model DSPG-IC-2-U232,
2-channel, UART-to- RS-232-C This
card is shipped with one RS-232-C interface in
wired as a "DCE" (Data Communication
Equipment), with a female, 9-pin, DB-9
connector labeled "TO DTE", and
one RS-232-C interface wired a " DTE"
(Data Terminal Equipment), with a male, 9-pin,
DB-9 connector labeled "TO DCE".
(This standard configuration can be
changed upon request at the time of order).

Block diagram of the Model DSPG-IC-4-U232,
4-channel, UART-to- RS-232-C This
card is shipped with the RS-232-C interface in
Channels 1 and 3 wired as a "DCE"
(Data Communication Equipment), with female,
9-pin, DB-9 connectors each labeled "TO
DTE", and the RS-232-C interface in
Channels 2 and 4 wired as a " DTE"
(Data Terminal Equipment), with male, 9-pin,
DB-9 connectors labeled "TO DCE".
(This standard configuration can be
changed upon request at the time of order).
