2600 Family Instruction Manual 3 Chapter 1 : Introduction
1.3 Module Network Topology
The MM has sixteen RJ-45 jacks—referred to as IOM ports—
which may be connected to IOMs by means of standard
Category-5 patch cables. These jacks supply power and
communication signals to the connected IOM.
Every IOM has an RJ-45 jack which may be connected to any
of the sixteen IOM ports on a MM. The connected MM will
then act as a client of the IOM.
A high degree of flexibility is permitted with respect to the
module network topology:
• Each IOM port may be connected to an IOM or left
disconnected.
• Any IOM type may be connected to any IOM port.
• All of the IOM ports may be left disconnected, in which
case the MM’s gateway functions are simply not utilized.
1.3.1 Module Network
The MM serves as a client of all connected IOMs, and also as
an IOM gateway for one or more Ethernet clients.
The IOM may be connected to any of the MM’s IOM ports by
means of a standard Category-5 patch cable as shown in Figure
3. Although not shown in Figure 3, as many as 15 additional
IOMs may be connected to unused IOM ports as required.
Figure 3: Connection for a Module Network
In Figure 3, the Ethernet client is not connected directly to the
2601, but is instead connected to a switch. The switch, in turn,
is connected to the MM.
If the MM will be connected directly to an Ethernet client, a
crossover cable must be used in place of the standard
Category-5 patch cable. This would be the case, for example,
if the MM is connected directly to an Ethernet interface card on
a computer.
1.3.2 Setting the IP Address
Network configuration settings and firmware upgrades can be
uploaded into the MM’s flash memory when it is connected as
described below.
During the firmware upgrade process, a local computer will act
as a setup manager for the target MM. The computer must
have an available RS-232 port, which connects to the MM’s
COM4 port by means of an RS-232 null modem cable as
shown in Figure 4.
Figure 4: Connection for Network/Firmware Reconfiguration
A utility program, Cfg2601.exe, is included with the 2600
distribution media. When executed in conjunction with the
hardware shown in Figure 4, this program will enable you to
examine and modify network settings and upload new
firmware onto a 2601.
The MM’s default IP address is 10.10.10.1 as shipped from the
factory. To change the IP address:
• Connect your hardware as shown in Figure 4.
• Run Cfg2601.exe. For example, invoke with “Cfg2601 2”
if the MM is connected to COM2 on the PC.
• Cycle power on the MM or wait for it to self-reset in
response to a network communication timeout.
• Select the “Change network configuration” option.
• Enter the new IP address.
• Select the “Run application firmware” option.
• Select the “Exit program” option.
