2.4.2.1 Switch With End of Line Resistor
Please refer to Figure 3 for connecting the SIM100 to a switch with an end of line resistor. This figure shows the connection of the monitored switch to switch channel 1 via the terminals named SW1A and SW1B. Connections to other switch terminals are similar.
