2. Before Using CRSC
Creating a Network
Rotary Switches
The 16-position rotary switch located on the front of a router or remote panel module is used to
determine a device’s initial IP address. Routers and remote panel modules usually come from the
factory with the switch set to 1. Once the frames are added to your network, you can use CRSC to
assign a different IP addresses, if you want. After that, the rotary switches are generally irrelevant.
The switches have hexadecimal position numbers from 0 to 9 and A to F. In hex notation, each let-
ter represents the following:
A = 10, B = 11, C = 12, D = 13, E = 14, F = 15
The switch is then added to a present number to create the initial IP address for the router or panel.
If a rotary switch is set to zero (0), the router or panel reverts to the factory default state, not to a
previously set state.
In the following, the subnet is represented by xxx.yyy.zzz:
For CR Series routers, IP address = xxx.yyy.zzz.sss where sss = switch value + 100.
For CQX routers, IP address = xxx.yyy.zzz.sss where sss = switch value + 200. Use only a
switch setting in the range 1–4 (addresses 201 to 204).
For remote panel modules, IP address = xxx.yyy.zzz.sss where sss = switch value + 50.
Using these formulas, a router and a control panel can have the same switch setting because each is
being added to a unique number. However, two routers or two control panels cannot have the same
switch setting because the resulting number would be the same creating identical IP addresses.
Remember that each device must have a unique IP address. If the devices are on the same subnet,
use the rotary switch setting plus the value listed above to create the default, IP address making
sure that the frame number is unique.
Remember that CQX routers and control panels must be on a separate subnet.
For instructions on setting switch settings, see How to Add Routers to a Network on page 20 and
How to Add Remote Panels to a Network on page 21. After you add the router or remote panel to
the network, you can change its IP address using CRSC. See How to Change Ethernet Settings on
page 22.
Initial Assembly
During the initial physical assembly of routers, panels, and remote panel modules, you need to
ensure that:
• All routers and remote panel modules have their rotary switches set to unique settings before
adding them to the network
• The switch settings of the routers and remote panel modules are non-zero and distinct.
Powering Up Re-initializes
A router or remote panel module re-initializes to its factory default settings if you power it up with
the rotary switch set to zero (0). If you reset the frame by accident, and the frame is in your net-
work, you will have to add the frame again and reconfigure it.
