RS232 Communications Connections
Note: the RS232 cable is not included as a standard accessory. However, TE Technology can provide this as
optional accessory, part number MP‐3023. If using the MP‐3023, connect the leads as follows:
red lead to JP5‐9
clear (or white) lead to JP5‐8
black lead to JP5‐7
Note: other connections to controller have been removed for the sake of clarity.
Note: If you are using a USB to RS232 converter, some converters might induce electronic noise and interfere with
communication. If this occurs, install a 0.001 microfarad, 50V‐ rated, ceramic capacitor across JP5‐7 to JP5‐8.
