Control Port

Selects the TCP/IP physical interface: Normal (10BaseT Ethernet) or SLIP using the RS-232 serial port. Choices: NORMAL or SLIP

If the Control Port option is set to SLIP, the RS-232 port cannot be used as a terminal interface.

IP Address

This is the IP address that uniquely identifies the TDU 120e on a TCP/IP network. This address is composed of four decimal numbers, each in the range of 0 to 255, sepa- rated by periods. This value is used for either the 10BaseT Ethernet or SLIP interface, depending on the control port setting.

Subnet Address

This defines which part of a destination IP address is the Network number. It is used along with the TDU 120e IP address to determine which nodes must be reached through the default IP Gateway. This value is set to 0.0.0.0 when the control port option is set to SLIP.

Default Router

All IP Packets destined for nodes not on the TDU 120e unit’s local network are not forwarded through this IP address. Normally, this address defines a router con- nected to the TDU 120e unit’s local network. This value is ignored when the control port option is set to SLIP.

SLIP Rate

This sets the baud rate for the Chain-In port when used as the SLIP connection for SNMP management. Choices: 1200, 2400, 9600, 19200, 38400
