Ethernet LAN Port
The Ethernet LAN port is an RJ-45 receptacle with a 10 Base T (or 100 Base T/Tx for 220 MHz and 290
MHz models) Ethernet connection and Auto-MDIX. Refer to the following table for pin-out descriptions
and Section 4.4.6 to configure the LAN settings for this port.

The name shows the default function. Given the Auto-MDIX capability
of the Ethernet transceiver, Tx and Rx functions could be swapped.
1.3.3.2.
SETUP and COM Ports
The SETUP and COM serial connections are DE-9F RS-232 ports. Refer to the
following table for pin-out descriptions and Section 4.3.4 for control line
configurations of DCD, DTR, RTS, and CTS control lines.
Serial port considerations:
Viper SETUP and COM ports are Data Communication Equipment (DCE) devices.
In general, equipment connected to the Viper serial ports is Data Terminal Equipment (DTE) and a straight-through
cable is recommended.
Note:
If a DCE device is connected to the Viper serial ports, a null-modem cable or adapter is required.
