Configuring the Model 1133A
(c) For Modbus, make sure to select the Modbus RTU Mode below.
(d) For Vorne Output, make sure to check the Vorne Output. Select time zone and voltage
phase: UTC AV, UTC BV, UTC CV, Local AV, Local BV, Local CV. See Appendix E
6. Click the OK button if you are finished configuring, otherwise continue configuring other
options.
7.3
Configure Ports - Ethernet
This section describes setting up the basic values for the 1133A Ethernet port. This includes the IP
address, subnet mask and Port Number. All of the different protocols are available except Vorne,
which is not defined for Ethernet.
1. Begin configuring the Ethernet port by opening the Configure Ports window and selecting
Ethernet on the left panel.
NOTE:
Power cycle the 1133A
after configuring the IP Address,
Subnet Mask, and Port Number or the new values will not be active. Prior to power-cycling,
the front panel will reflect the new IP address, but the new connection parameters will not
be activated without power cycling the unit.

2. It is best to use this window for two things: (1) viewing the Ethernet connection and (2)
making Protocol changes. If you want to change the port settings on the active connection,
you will still be connected at the previous settings. Only after power-cycling the 1133A will
the new settings become active.
3. If the connection protocol is Modbus, choose ON or OFF for the desired action and then click
the OK button.
4. If the connection protocol is DNP, choose ON or OFF for the desired action and choose a
value for Max App Frag Size (see Section 7.6). Values range from 1 to 2048.
5. If the desired connection protocol is C37.118, then you will need to decide if you want to use
PMU-1, PMU-2 or PMU-3 Ghost.
