1 Description
The ePAQ-9405 is a communications gateway and distributed I/O module, in a 19 in. 2U
enclosure (rack-mount or DIN-mount). It provides 12 status inputs, 4 analog 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-9405 communications protocols includes DNP 3, Modbus, and QUICS Servers, as
well as DNP 3, Modbus, PLCC, Event Logger, and Web Access 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-9405 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-9405 are under software control. The program
resides in dedicated non-volatile program (FLASH) memory area.
The ePAQ-9405 is configured using QEI
’s ConfigWiz 2.0 Configuration Program, and
a ePAQ-9405 Template. Refer to the ConfigWiz 2.0
User’s Guide (UM-2018) and
the ePAQ-9405 addendum contained in the same manual.
