Creating a Network
Network Speeds
Compact router networks are Ethernet LANs (100
Mb/s, UDP). That means they are reasonably
fast, and have potentially many network configuration options. However, no matter how fast the
network is, the amount of network traffic increases exponentially with the number of devices on the
network. At some point, the traffic exceeds the capacity of the network. The practical limit is 4
compact routers and about 16 remote panel modules.
Cabling
In general, router networks and machine control ports use ordinary Ethernet cable and connectors
(RJ-45). However, some frames have DE9 connectors. To make network connections to these
devices, you will need to acquire DE9-to-RJ45 cables.
Analog audio connectors are DB25. Each connector supports 8 audio channels (4 stereo pairs). You
will need to acquire breakout cables to connect individual analog audio devices, such as Miranda’s
WC0053 breakout cable.
CQX Networks
A CQX router must be operated with a CQX control panel (or automation). Do not place a CQX
router on a subnet with other routers. However, you can have more than one subnet dedicated to
CQX routers.
Figure 3-3 shows the ways a “clean and quiet” router can be connected:
Figure 2-2. Figure 3-3. CQX Network
The CQX panel can be local (mounted on a CQX router) or it can be remote (mounted on a remote
panel module). The remote CQX panel then must be connected to the CQX router by an Ethernet
switch. It is possible to use both a captive panel and a remote panel.
Unlike other compact routers, the CQX routers have two rotary switches. You must set both
switches to an appropriate value.
Mode Rotary Switch
The ‘Mode’ rotary switch configures the router’s video format. Set this 16-position rotary switch to
a position in the range 0–5 according to this table:
