Chapter 2 Extended I/F Specification Interface circuit Prepare a circuit like the one below on the device side. Input Connector TM-C7500 side device side Input port Output signal 2 Because the TM-C7500 does not have a terminal for providing power to a device, prepare a power supply for the V pull-up on the device side. R pull-up : Set a resistance value to ensure 10 mA or lower. 19 4-8,10pin • An open drain signal is input to the TM-C7500. • When inputting a level signal, set high to 2.6 V or higher and low to 0.45 V or lower. • Because the TM-C7500 does not have a terminal for providing power to a device, prepare a drive power supply for the circuit on the device side.
