Using multiple Matrox Altiz units
Connecting the auxiliary input and output lines
Two power configurations allow the current to flow from the AUX_OUT pin to the AUX_OUT_COM pin
(or vice versa) and from the AUX_IN pin to the AUX_IN_COM pin (or vice versa). In one configuration,
the inputs are sourcing current and the outputs are sinking current. In the second configuration, the
inputs are sinking current and the outputs are sourcing current.
Sourcing Inputs - Sinking Outputs
AUX_IN_COM = +VDC
AUX_OUT_COM = -VDC
-
Connecting AUX_IN_COM and AUX_OUT_COM from multiple Matrox AltiZ units to a single +VDC
and -VDC can be done by using a power distribution block (ex: Phoenix Contact
2/16)
-
The rated current for each AltiZ is 500mA @ 24 V (12 W), as specified in the Electrical
Specifications section of Appendix B in the Installation and Technical Reference manual.
