4-3 MGP Series • Software Configuration and Control
PRELIMINAR
Y
N The cables used to connect the RS-232/422 port to a computer or control system
may need to be modified by removing pins or cutting wires. If unneeded pins are
connected, the processor may hang up.
Communication software
There are several programs that enable you to connect the MGP to a computer
or control device via the RS-232/422 interface, and to enter commands.
HyperTerminal for Windows is one such program that is commonly used on PCs.
In addition, the MGP has a Windows-based control software program, discussed
later in this chapter, that is available through the RS-232/422 port, the front panel
Config port, or via Ethernet. (See the MGP software’s help file for information on
using the software to configure the MGP.)
For any program that you use, set up communication using the following protocol:
Baud rate: 9600
Stop Bits: 1
Data bits: 8 Flow Control: None
Parity: None
Setting Up Internet Communication
The rear panel Ethernet connector on the MGP can be connected to an Ethernet
LAN or WAN. This connection makes SIS control of the MGP possible using a
computer connected to the same LAN or WAN.
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable. A cable wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped. RJ-45

Ethernet connection
The cable can be terminated as either a patch cable or a crossover cable (figure 4-3)
and must be properly terminated for your application:
• Patch (straight) cable — Connection of the ISS to an Ethernet hub, router, or
switch that also hosts a controlling computer
• Crossover cable — Direct connection between the ISS and a computer
Default address
To access the MGP via the LAN port, you need the MGP’s IP address. If the
address has been changed to an address comprised of words and characters,
you can get the actual numeric IP address using the front panel (see “ Comm./IP
Configuration Menu ” in chapter 3, “Operation”). If the address has not been
changed, the factory-specified default is 192.168.254.254.
