DIO Port
The front of the EMG unit has two Digital Inputs and one Relay Output. DIO ports can be used in
Events as a trigger (inputs) or an action (relay output). Specifications for the DIO port:

Two configurable inputs suitable for TTL input levels and tolerant up to 30VDC input voltage.
The DIO inputs can be used to monitor the current status of any attached sensor.

One independently isolated mechanical form-C relay, supporting 1A 24V. When the relay is
energized/turned on, the relay is closed, connecting both relay ports on the I/O connector
through the relay. When the relay is turned off, the signal path is open, disconnecting the relay
ports on the I/O connector.
DIO terminal block (in the UIs the ports are designated as Front #1, Front #2 and Front Relay):
Parity Parity checking is a rudimentary method of detecting simple, single-bit errors.
From the drop-down list, select the parity. The default is none .
Flow Control A method of preventing buffer overflow and loss of data. The available methods
include none , xon/xoff ( software), and rts/cts (hardware). The default is none .
Timeout The number of minutes (1-30) after which an idle session on the console is
automatically logged out. Disabled by default.

Connecting
If selected, when you connect to the console port with a terminal emulator, you will
see the last lines output to the console, for example, the EMG boot messages or
the last lines output during a CLI session on the console.
Group Access If undefined, any group can access the console port. If one or more groups are
specified (groups are delimited by the characters ' ' (space), ',' (comma), or ';'
(semicolon)), then any user who logs into the console port must be a member of
one of the specified groups, otherwise access will be denied. Users authenticated
via RADIUS may have a group (or groups) provided by the RADIUS server via the
Filter-Id attribute that overrides the group defined for a user on the EMG. A group
provided by a remote server must be either a single group or multiple groups
delimited by the characters ' ' (space), ',' (comma), ';' (semicolon), or '=' (equals) -
for example "group=group1,group2;" or "group1,group2,group3".
