Operating a Stand-Alone Network
Stand-Alone Network
Stand-Alone Network
A stand-alone network includes 1–4 routers, possibly some remote panel modules (up to 15),
and an Ethernet switch. A remote panel module, to be useful, must have a control panel
1
attached. (Automation is possible, but this document does not address automation.)
A PC running configuration software can optionally be connected to the network.
Operation
Startup
To power up a router or a remote panel module, connect the 4-pin connector the power supply
to PS1 or PS2. Then plug the power supply into AC power outlet. If you have chosen to use two
power supplies for redundancy, connect one to PS1 and the other to PS2.
At power-up, a router loads stored program code into its internal FPGA and restores its previous
operational state. (The “state” includes the crosspoint map between inputs and outputs and
which of the outputs are locked.)
At power-up, a router detects the presence or absence of a video reference signal. The AES
routers switch to synchronous mode if a video reference is present.
At power-up, routers and remote panel modules “discover” the presence and state of the routers
in the network.
 It might be convenient to connect all your CR Series power supplies to a power bus that you
can switch on and off. A fully populated network requires 20 power supplies (or up to 40 if
you are providing redundant power). Under normal operation, a fully populated network
draws less than 3 A at 120 VAC.
At power-up, a control panel’s ‘Panel Lock’ button is on (red). You must turn Panel Lock off
before you can use the panel. This is true whether the control panel is mounted on a router or a
remote panel module.
At power-up, a control panel mounted on a remote panel module lights a subset of its level
buttons, depending on the levels selected at each of the routers in the network. There are 4 situ-
ations to consider:
1 If there is one router (level in the range 1–4), one level button is illuminated but is inoperable
because, with one level, level selection is not possible.
2 If there is no router whose level is in the range 1–4, no level button is illuminated and all are
inoperable. The network routers are configured in error and inaccessible.
3 There are from 1 to 4 routers whose levels are distinct and in the range 1–4. The level but-
tons that correspond to the levels of the routers are illuminated and operable.
4 There are from 1 to 4 routers whose levels are not distinct in the range 1–4. The level buttons
that correspond to the levels of the routers are illuminated and operable. However, the
router network will misbehave in unpredictable ways.
