7.12.11 DIO2 - Digital I/O Connector
Connector DIO2 provides 24 bidirectional I/O lines. These I/O lines can
sink 12 mA each, but source current is limited to 5 mA when shorted to
ground. +5 volts is provided on Pin 49 through JPDIO1(see “JPDIO2 - Power
Enable (+5 VDC) to Pin 49 of DIO2” on page 52) to power external devices.
The user must ensure that current does not exceed 1 A or damage may
result.
NOTE The EBC-C413 provides 48 bidirectional I/O lines (24 lines at DIO1 and 24
lines at DIO2).
