COM2 PORT NOTES:
RXD+ / RXB and RXD– / RXA are data sent to the radio to be transmitted
•
• RXD+ / RXB is positive with respect to RXD– / RXA when the line input is a "0"
• TXD+ / TXB and TXD– / TXA are data received by the radio and transmitted
• TXD+ / TXB is positive with respect to the TXD– / TXA when the line output is a "0"

4.8 Ethernet Interface (RJ-45)

In x710 mode, the transceiver's Ethernet Port is used for radio manage-
ment only. The port has built-in MDIX (auto-sensing) capability,
allowing either a straight-through or crossover cable to be used.
Figure 16 and Table 9 show pinout data for the Ethernet port.
The Ethernet port can be used to support Telnet or web-based radio
management. Telnet provides the same user interface available with
.
