Serial DB9 Port with IRIG-B Support
Figure 26: Serial DB9 Port Pin Configuration
d
In RS232 DTE mode, ports transmit to DTE devices on pin 2 and receive from DTE on pin 3.
NOTE
Pins 7 and 8 are connected internally. In RS232 mode, these pins enter a high impedance state. A
DTE that asserts RTS will see CTS asserted. However, the device will not perform hardware flow
control.

e
The DSR, DCD and DTR pins are connected together internally.
f
In RS232 mode, the RJ45 ports conform to EIA-561 DTE, which transmit on TXD and receive on RXD.
NOTE
Pins 1, 2 and 3 and pins 7 and 8 are connected internally. In RS232 mode, these pins enter a high
impedance state. A DTE that asserts RTS will see CTS asserted. However, the device will not perform
hardware flow control.
