1 General Description
The ePAQ-9410 and ePAQ-9420 (ePAQ-94XX) Multifunction Gateways are part of the
QEI family of Distribution Automation Products. They are housed in a 19 inch 3U rack-mount
enclosure, and are intended for installation in harsh electrical utility sub-station environments.
All connections, switches, and indicators are accessible from the front panel. The ePAQ-9420
provides additional communications capabilities vs the ePAQ-9410. Both units include an
additional option for more comm ports, using the eXP-9430.
The ePAQ-94XX is configured using QEI’s ConfigWiz 2.0 Configuration Program, and a
ePAQ-94XX Template. Refer to the ConfigWiz 2.0 User’s Guide (UM-2018) and the ePAQ-
94XX addendum contained in the same manual.
1.1 ePAQ-9410 Features
The following features are provided on the ePAQ-9410 :
Wide input voltage range (48-125Vdc/120-277Vac)
Two Bell 202T modems (bit or byte oriented).
Option DIP Switches (front panel accessible)
System Indicator LEDs.
Front panel USB maintenance port for Windows based diagnostic and configuration software.
SD Memory Card support.
Irig Time interface (modulated Transmit/Receive BNC, digital RS-485 or Serial Fiber).
NTP time (peer or client) or PTP (Precision Time Protocol.
Three High Speed RS-422 ports (RJ45 x3) for I/O expansion.
Two RS-232 ports (bit or byte oriented) (RJ45 x2)
Four RS-232/RS-485 combo ports (RJ45 x4)
Two USB Host ports for thumb drives or other bulk storage, etc.
Two Ethernet ports 100BaseFX (Multimode ST Connectors)
Four Ethernet ports 10/100BaseT (RJ45 x4).
All communications ports are available via RJ45 connectors, and have LEDs to indicate
communications status (TX, RX, Link, H/S). The RS-232/RS-485 combo ports are substation
hardened.

ePAQ-9410 / ePAQ-9420 User’s Guide UG-1071
2  General Description Copyright 2017 QEI
Ethernet and serial fiber ports have ST connectors for Multimode Fiber with TX/RX LED
indicators.
RS232/RS485 combo ports can be tri-stated for redundancy capability between two
units.
USB Type B maintenance port supports Windows based PC software for unit
configuration and diagnostics.
The ePAQ-94XX is housed in a 19 inch rack mount (or surface mountable) 3U
enclosure. It includes a universal power supply that accepts 48 to 125Vdc, or 120/240/277Vac
50/60Hz input.
1.2 ePAQ-942x Features
The ePAQ-9420 includes all of the ePAQ-9410 features, while providing an additional
sixteen RS-232/RS-485 ports (via RJ45 connectors) or eight serial fiber ports (via Multimode
ST connectors). Like the ePAQ-9410, the additional ePAQ-9420 RS-232 ports can be tri-stated
for redundancy applications, when two ePAQ-9410/20 device ports are wired in parallel. There
is an interprocessor link, which allows a slave ePAQ to take over the operation of attached RS-
232 devices, when the heartbeat goes missing from the Master ePAQ
The ePAQ-9425 is similar to the ePAQ-9420, but provides all 16 upper level ports to be
in the rear of the device as RS-232 / Rs-485 DB9 ports. It will only come in one configuration
of the rear port of 8 isolated and 8 non isolated DB 9 ports

6.2 Ports 3/4/5/6 (J2B/J2A/J2D/J2C): RS-232/RS-485
The ePAQ-94XX includes four byte-oriented UART serial RS-232/RS-485 ports. They are
intended for communications with IED devices, etc, and are available as four RJ45 connectors (2x2).
Each connector can be used as either RS-232, or RS-485, depending on which pins are used. When
configured for RS-232 interface, the remaining RS-485 signals can be used to carry IRIG-B time code.
This RS-485 signal path does not disturb the RS-232 UART serial data path. Port Speed: 1200 to
115.2 kbps

Connector Pinout :
Connections for J2B, J2C, and J2D are identical to those listed in the table above for J2A.
6.2.2 Redundancy Capability:
The RS232/RS485 ports are all tri-stateable for redundancy capability between two ePAQ-
9410/9420 units. Redundancy is accomplished by asserting the “Comm Port Disable” input line
located on ethernet copper port J12C pin 8.
Additionally, the input disable line is driven up to the Comm Port expander board in the ePAQ-
9420 (via a DIP switch), so that all comm ports in the ePAQ-9420 can be disabled.
Two other ethernet copper ports (J12B and J12D) have a “Disable Comm Ports” output pin. The
output pins are each driven independently by the ePAQ-94XX processor. They are for disabling
other ePAQ-94XX or eXP-9430 units.
6.2.3 Isolation/Surge protection
Each of the RS232/RS485 communications ports is isolated from logic common (1KVdc Isolation).
Surge protection is provided using TVS clamping devices that clamp the lines of each
communication port to its’ own isolated common.
6.2.4 RS-485 Termination
RS-485 termination resistance is built-in to each port. Termination resistors are high value (3.9K)
to allow RS-485 ports from multiple ePAQ-9420 units to be placed in parallel.

6.3 Port 7 (J3) : Serial/IRIG-B Fiber
6.3.1 Introduction
The IRIG-B Fiber port consists of a 10BaseFL compatible serial fiber optic transmitter and
receiver. The port receives IRIG-B time signals, and can also be software configured for use as a
generic UART serial data channel.
The port receives IRIG-B time signals, and via loop config can pass them out to another
deivce. IRIG-B time code can be received from many sources:
IRIG-B modulated BNC input
RS-485 input
Fiber IRIG-B input
NTP time code received over the TCP/IP network (Possible future enhancement; not in
initial product release).
