Table 285
Connectors J1, J2, J3, and J4 pin assignments
Pin # Signal Purpose in DTE mode Purpose in DCE mode
1 DCD Data Carrier detect (Note 1) Data Carrier detect (Not used)
2 RD Transmitted data Received data
3 TD Received data Transmitted data
4 DTR Data terminal ready Data terminal ready (Note 2)
5 GND Signal Ground Signal Ground
6 DSR Data set ready (Note 1) Data set ready
7 RTS Request to send (Not Used) Request to send (Note 2)
8 CTS Clear to send (Note 1) Clear to send
Note 1: In DTE mode the signals CD, DSR, and CTS are tied to +12 volts to signify that the port on
the QSDI paddle board is always ready to transmit and receive data. This mode is set to connect
to a terminal device (DTE).
Note 2: In DCE mode the signals DTR and RTS are tied to +12 volts to signify that the port on the
QSDI paddle board is always ready to transmit and receive data. This mode is set to connect
to a modem device (DCE).
Configuring the QSDI paddle board
Configuring the QSDI paddle board to work in a system consists of setting
these option switches for each serial port:
•
Baud rate
• Port address
• DTE/DCE mode
The QSDI paddle board has fourteen option switches, SW2–13, SW15-16.
Figure 246 "NT8D41BA QSDI paddle board" (page 723) identifies the
location of option switches on the QSDI paddle board. Learn how to set
these switches in the following sections.
Once the board has been installed, the system software must be
configured to recognize it. Instructions for doing this are found in the
section titled
“Software service changes” (page 728) .
Option switch settings
Baud rate
Switches SW13, SW10, SW11, and SW12 determine the baud rate for
ports 1, 2, 3, and 4, respectively. See the settings for these switches in
Table 286 "NT8D41BA baud rate switch settings" (page 726) .
