Eight yellow LEDs to indicate the status of I/O lines (see RS232 port and
Expansion Connector topic).
·
Four jumpers to select between RS232 port and expansion connector (see RS232
port and Expansion Connector topic).
·
Two buttons: setup (connected to the MD line of the EM1206), and reset
(connected to the RST line).
·
Green and red status LEDs (connected to SG and SR lines of the EM1206). Further
information on status LEDs can be found in Status LEDs.
