Connector pin assignments 989
Table 414 "Connector J1 pin assignments" (page 989) shows the pinouts
for connector J1, and Table 415 "Connector J2 pin assignments" (page
989) shows the pinouts for connector J2.
Table 414
Connector J1 pin assignments
Pin
number Signal Purpose in DTE mode Purpose in DCE mode
1 FGD Frame ground Frame ground
2 TD Received data Transmitted data
3 RD Transmitted data Received data
4 RTS Request to send (not used) Request to send (Note 2)
5 CTS Clear to send (Note 1) Clear to send
6 DSR Data set ready (Note 1) Data set ready
7 GND Ground Ground
8 CD Carrier detect (Note 1) Carrier detect (not used)
20 DTR Data terminal ready Data terminal ready (Note 2)
Note 1: In DTE mode, the signals CD, DSR, and CTS are tied to +12 volts (through a resistor) to
indicate that the QSDI port is always ready to transmit and receive data.
Note 2: In DCE mode, the signals DTR, and RTS are tied to +12 volts (through a resistor) to indicate
that the QSDI port is always ready to transmit and receive data.
