Port Description

Specifies a description for the port.

Enter a description of up to 62 alphanumeric characters. Do not use the following characters:

( ; ' " ) ]

I/F Type

Specifies the daughter card as the interface type.

Select DCARD.

Port Speed

Specifies the data rate on the IP connection.

Unless network bandwidth is at a premium, we do not recommend that you change this value from the default of 16,000 bps.

Enter a number from 1.000 through 25.500 KHz. The port speed must be a multiple of 100 bps.

Direction

Specifies the direction of the circuit. Although the IP circuit connection through the network is full duplex, an IRIG-B circuit is actually a simplex application, and the daughter card can operate only in Rx or Tx mode and not both at the same time.

Select one:

• RX—The end of the circuit that recovers IRIG-B from the attached cable and generates IP packets toward the network.
• TX—The end of the circuit that accepts IP packets, extracts the IRIG-B data codes, and transmits IRIG-B signaling output onto the cable.

Output High Volts Level

This option appears only if you set the direction of the port to Tx.

Specifies the high output level, which is measured in peak-to-peak voltage. This setting is based on a 50 ohm termination

Enter a number from 0.00 through 7.85 volts peak-to-peak.

Output Low Volts Level

This option appears only if you set the direction of the port to Tx.

Specifies the low output level, which is measured in peak-to-peak voltage. This setting is based on a 50 ohm termination.

Enter a number from 0.00 through 7.85 volts peak-to-peak.

Clock Cfg

Specifies the type of clocking for the bundle.

Select one:

• Custom—The custom clocking configuration is used.
• Voice/IRIG-B Master End—This end of the circuit generates a clock signal and sends it to the remote end.
• Voice/IRIG-B Slave End—This end of the circuit receives the clock signal from the remote end. The clock slave uses its period to determine when to sample data and how to transmit data across the link.
