1 INTRODUCTION
This document describes the basic hardware components of the baseboard MB/935A.
1.1 Safety Guidelines
Please read the following safety guidelines carefully! In case of property or personal
damage by not paying attention to this document and/or by incorrect handling, we do
not assume liability. In such cases any warranty claim expires.
ATTE TIO !
Observe precautions for handling – electrostatic sensitive device!
• Do NOT turn on the power suppl while connecting an cables, especiall the pow-
er cables. This could cause damaged board components! First connect the cables
and THEN turn the power suppl on.
• Discharge ourself before ou work with the device, e.g. b touching a heater of
metal, to avoid damages.
• Sta grounded while working with the device to avoid damage through electrostat-
ic discharge.

3.7 JP1: RCM Ju per
The MB/935A offers a jumper for the Remote Console Mode (RCM). This allows to control
the DIL/NetPC via a terminal emulation program over the UART based serial COM port (se-
rial-based CLI = Command Line Interface).
To disable RCM remove the jumper cap of the RCM jumper. This frees the UART based seri-
al COM port for application usage.
