Creating a CRSC Network
CR Series products (and CRSC) communicate on an Ethernet LAN. There are three main reasons
to create a network:
• To perform multi-level operations, such as ‘takes’ and locks.
• To operate routers or a network of routers remotely (e.g., from a separate room).
• To make use of CRSC features, such as configurable remote panels. (But remember that it is
actually the remote panel module that is configurable.)
CRSC can access multiple subnets. Each subnet can include the following items:
• From 1 to 16 remote panel modules (with attached control panels).
• From 1 to 4 compact routers. You can mix CR Series routers of any size and type according to
your requirements.
 If you are also using any CQX routers and control panels, a second, separate subnet must be
created for the CQX products.
The control panels and routers communicate by sending messages across the network. If any
routers or control panels on the network have duplicate IP addresses, the devices are not distin-
guishable and the network will not functions properly. CRSC will notify you of any duplicate IP
addresses and tell you which frames are inaccessible on a specific subnet.
You can create multiple CRSC subnets. CRSC can detect and manage all subnets as long as your
configuration PC can connect to the different subnets.
IP Addresses
An IP address is a 32-bit number usually expressed by four 8-bit values (octets) in decimal nota-
tion separated by periods: 192.168.2.87 (for example). The 32-bit number has two parts: a
subnet identifier and a device address with the subnet.
For example, if a router’s full IP address is 192.168.2.87, and the subnet mask is 24 bits, the
router’s address is 87 and the subnet is 192.168.2.xxx.
Subnets
A subnet allows a single large network to be organized into smaller sub-networks. Typically, a
subnet may represent all the machines at one geographic location or on the same local area
network (LAN).
A CQX router and control panel must be on its own subnet.
A router can receive commands only from a control panel on the same subnet.
