2.2.2 Attaching the UART-ISO Daughter Board to the OMU1-S-RF
Attach the UART-ISO daughter board to the OMU1-S-RF for use with external development boards.
External development boards are customer-supplied hardware incorporating their communications
module and debug interfaces. Their debug interfaces are typically RS-232 or USB cables with direct
connections to a PC. The daughter board incorporates signal isolators to protect the external
development board hardware and its attached PC.
Attach the UART-ISO daughter board to the OMU1-S-RF’s UART cable as shown. Take note of the
cable’s
The UART-ISO daughter board does not supply power to the attached external development board. The
female connector J2 is provided for attaching the external development board. The J2 pin assignments
are as follows:
The UART-ISO daughter board does not support 1.8V signal levels.
