1 Description
The ePAQ-9400 is a communications gateway and distributed I/O module, in a 19 in. 2U
enclosure (rack-mount or DIN-mount). It provides 16 status inputs and 3 momentary or
latching control points.
Hardware communications ports include RS-232, Fiber, RS-485, and 10/100 Ethernet
(via copper or Fiber). An IRIG port (unmodulated IRIG via RS-485 or Fiber;
modulated IRIG via BNC connector) and a USB maintenance port are also provided.
ePAQ-9400 communications protocols includes DNP 3, Modbus, QUICS, Event Logger
and Web Access Servers, as well as DNP 3, Modbus and PLCC Clients.
I/O and input power connections are via plug-in terminal blocks. Front panel mounted
power and local/remote rocker switches are provided, as are dip switches for address
settings. LEDs provide indications for status, controls, local/remote and communications
port activity.
The ePAQ-9400 provides highly secure control and monitoring of status points with 1
msec Sequence of Events (SOE) and time tagging in critical environments where
highly secure operation is required.
Local diagnostics and configuration are accomplished via a Maintenance Port (USB)
connection to a PC. The maintenance port is used to send/read configuration
settings and perform diagnostic functions.
Features include a real-time clock with power-failure backup circuitry (no battery
replacement required). The clock can be synchronized by an IRIG-B receiver through
BNC, RS485 or fiber optic port or through its DNP3 communication ports from a
Master Station or Data Concentrator.
Input power options include 12/24/48/125Vdc, as well as 120/240/277Vac. A
local/remote switch is included for controls. LEDs provide indications for
communication port activity, status point keying, CPU heartbeat, system 3V power,
and local/remote switch position.
All of the operations of the ePAQ-9400 are under software control. The program
resides in dedicated non-volatile program (FLASH) memory area.
The ePAQ-9400 is configured using QEI’s ConfigWiz 2.0 Configuration Program, and
ePAQ-9400 Template. Refer to the ConfigWiz 2.0 User’s Guide (UM-2018) and the
ePAQ-9400 addendum contained in the same manual.

7.1 Port 1 (J3): USB Maintenance Panel
This port is a standard USB type B port for connection to a PC. It is used as a
Maintenance Port, to program and troubleshoot the ePAQ-9400. Using a PC with a
USB port and a straight USB type A-B cable, the ePAQ can be accessed in one of
two ways, 1) via ConfigWiz 2.0, to download configurations and flashload program
link files, 2) via HyperTerminal (or other such terminal emulator program), to gain
access to included test panel functions.

The eAQ-9400 includes three control points. Each control point can be configured as
a pair of momentary relays (one for “trip” and one for “close”) or as a single latching
relay (trip/close). See the ordering information to choose controls as momentary or
latching on a per point basis.
8.1 Momentary Form 1C Controls
Momentary Form 1C control points use two sets of form 1C (SPDT) contacts (one
set for Trip, the other set for Close) at the terminal blocks:
For the illustration above, T= Trip LED, C = Close LED. The relay contact schematics
above the terminal blocks are shown with relays in the un-energized state.
