This topic describes how to configure port parameters for IRIG-B daughter cards.
Adaptive clocking is configured by default on IRIG-B bundles, and the packet size is set to 64 bytes. The packet size combined with the default data rate of 16 Kbps, produces a packet rate of 32 pps, which is a good packet rate for adaptive clocking.
Before you begin:
To configure IRIG-B port parameters using CTPView:
Table 1: CTP Bundle IRIG-B Port Parameter Settings in CTPView
Field | Function | Your Action |
---|---|---|
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:
|
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:
