Pulse Output for EMR3
53
SP1 and SP2
• SP1 and SP2 are open collector outputs with an internal pull-up resistor (2.2K) tied to Input V. The output
voltage can be set to either 5, 12, or 24 volts depending on the location of the pulse voltage selector jumper
wire (see Figure 40).
• A low or 0 volt signal which indicates that the corresponding Display Head is in the delivery state
