This document serves as an addendum to the 2100 Family EZ-Tools Manual, specifically addressing incorrect information regarding RS-232 connections in Section 2.2.1.2 of the original manual (document number 31-000008-01). It clarifies the proper pinout for the RS-232 interface on the 21xx EZ_ICE board, specifying that TX connects to pin 2, RX to pin 3, and ground to pin 5.
TX connects to pin 2, RX connects to pin 3, and ground connects to pin 5.
A standard cable works if the EZ-ICE board is set up as a DCE device and the PC is a DTE device.
A null modem cable is required when connecting the EZ-ICE board to another DCE device.
