3.4.5. DIGITAL COMMUNICATION INTERFACES
Note
Ensure that there are no communication devices
connected until after start-up is complete.
3.4.4.1 E
THERNET
For network or Internet communication with the monitor, connect an Ethernet cable
from the Ethernet interface connector (see Figure 3-4) to an Ethernet port. Although
the default setting is DHCP-enabled, it should be manually configured with a Static
IP address (Section 6.1).
3.4.4.2 S
ERIAL
: RS-232
OR
RS-486
For Serial communication, connect a 9-pin serial cable from the serial connector J14
(see Figure 3-4) to a personal computer serial port. If communication cannot be
established, it’s possible that the cable is pinned differently, and the signal pinout
for the RS-232 connector can be swapped. See Section 6.2 for additional details.
