1.0 Overview
The RS-232 to RS-485 Convertor module converts RS-232 levels from a PC COM port to
RS-485 levels suitable for interfacing with the Equinox PRO101, PRO104 and PRO108
Production ISP programmers. The module provides an optical isolation barrier between the
PC COM port and the RS-485 bus which serves to protect the PC from ESD damage.
