Electrical Signals
By default, the output data is valid on the falling edge of the clock, as shown in Figure 8. The polarity of the output
clock may be inverted by toggling the Clock Polarity setting in either user interface. The RM RDMS™ can be
operated through its front panel interface or Ethernet-based remote client interface (Remote RDMS™ Client).
