User’s Manual for ION

-U

Status LEDs

The

status LEDs

for paths 1 and 2

provide a visual warning of an alarm condition.

The color of the LED indicates the severity of the alarm.

RU Expansion Ports

The RU DL and UL Expansion ports for path 2

and the RU DL and UL Expansion

ports for path 1

are QMA female connectors that are used to connect to the

Expansion ports of two RUs.

EU Expansion Ports

The EU DL and UL Expansion ports for path 2

and the EU DL and UL Expansion

ports for path 1

are QMA female connectors that are used to connect to the

Expansion ports of an additional EU such as an ION-U EU L 23/23.

Mains Connector

The EU receives its power through the Mains connector

. The type of connector

depends on the EU model. A 4-pin Amphenol connector is used for AC models and
standard DC models. A 7-pin Amphenol connector is used for DC models powered by
a dual cable supply (VDC/100).

Ctrl Connector

The Ctrl connectors

are DB-9 female connectors that are used for external

modem communication with RUs.

Local Port RS-232

The RS-232 ports

are standard DB-9 female connectors used for external

modem communication with another EU.

Alarm Connectors

The EU has two alarm relay inputs that can be used to monitor and report alarms from
external devices. The alarm connectors

are 5-pin Binder connectors.
