Figure 11: RS232/485 adapter
Note: If you connect an ADAM module to the unit, you cannot connect any RS232 PTZ
controllers to the unit. For additional information about connecting PTZ controllers to
the unit, see Connecting PTZ Controllers, page 16.
5. Connect the ADAM-4051 module to the power source as follows (see figure 12,
page 22):
• Connect the positive (+) wire of the power supply cable to the (R) +Vs connector
on the module
• Connect the negative (-) wire of the power supply cable to the (B) GND connector
on the module
Note: Each of the power connectors on the module will then have two wires connected
to it – one connecting it to the power supply, and one connecting it to the power
connectors of the ADAM-4520 converter.
Note: You may be able to use the MVG 400 to supply power to the modules by
connecting the power supply cables to the 12 VDC connector on the rear panel of the
unit. However, bear in mind that the unit can supply a maximum of 500 mA of power. If
the devices connected to the unit require more than this amount of power, you must
power some or all of them independently.
