6.4.3 Ethernet Performance
Ethernet performance on the MVI56E-MCMR module can affect the operation of
the MCMR application ports in the following ways.
 Accessing the web interface (refreshing the page, downloading files, and so
on) may affect MCMR performance
 High Ethernet traffic may impact MCMR performance (consider CIPconnect
(page 96) for these applications and disconnect the module Ethernet port
from the network).
6.4.4 RS-232 Application Port(s)
When the RS-232 interface is selected, the use of hardware handshaking
(control and monitoring of modem signal lines) is user definable. If no hardware
handshaking will be used, here are the cable pinouts to connect to the port.
