SRTP connections remain open after IP 

address changed

The Ethernet Interface does not terminate all open SRTP connections 

before changing its IP address. Once the local IP address has changed, 

any existing open TCP connections are unable to normally terminate. This 

can leave SRTP connections open until their underlying TCP connections 

time out. If quicker recovery of the SRTP connection is needed, modify 

the “wkal_idle” Advanced User Parameter to reduce the TCP keep alive 

timer down to the desired maximum time for holding open the broken 

connection. Refer to TCP/IP Ethernet Communications for PACSystems, 

GFK-2224, for details.

CPU time used for produced EGD 

Timestamps

Changing the Ethernet interface time via the CHTIME command does not 

affect the timestamp value within EGD exchanges produced from this 

Ethernet interface. The EGD timestamp value reflects the current CPU 

time. In Series 90-70 products and the Series 90-30 CPU364, EGD 

timestamps are taken from the Ethernet interface and do reflect CHTIME 

modifications.

ENIU stale data during run mode store 

of EGD

In a large PPS system running 20 ENIUs, when a Run-mode Store is 

performed that deletes the EGD exchanges for 10 of the ENIUs, the other 

ENIUs will see the status on their exchanges indicate consumption 

timeouts during the RMS. At the completion of the RMS, the exchanges 

operate normally.

Internet Explorer 8 may require setting 

changes when using Web pages on 

RX7i

It may be required to disable the pop-up blocker when using Internet 

Explorer 8 with the Web pages supplied with the RX7i Ethernet firmware. 

To disable the pop-up blocker, in the Internet Explorer toolbar, select

Tools->Pop-up Blocker->Turn Off Pop-up Blocker

Note: If you have the Google toolbar installed, the Google pop-up 

blocker may also have to be disabled. 

It may also be required to disable configuration scripts when using 

Internet Explorer 8. In the Toolbar select Internet Options. In the Internet 

Options dialog box click the “Connections” tab, click the “LAN settings” 

button, and make sure the box beside “Automatically detect settings” has 

a check in it. If it does not, click the box next to “Automatically detect 

settings” to enable this setting.
