Overview 3
Chapter 1: Overview
The IEPS-1000 port server (referred to as NDS throughout this manual) provides
communication between peripheral devices and computers connected to a network. When
the NDS is connected to your LAN and to one or more peripherals, it manages network traffic,
routing it to the correct device. For example, the network diagram below shows how the NDS
might be used to allow a PCs to access data from one or more KEP Flow Computers that are
located on the local or remote network.
IEPS-1000 Features
The NDS offers the following features and benefits:
•Easy web-based set up and configuration
•Open systems communications for multi-site data networks
•Can be used in a variety of data communications applications
•1 DB-9 (with screw-down connectors)
•RS-232 serial communication

NDS Features4

3. Operation
Hardware installation is documented in this manual.

Using the NDS6
Refer to the IEPS-1000 Administrator's Guide for configuration and operation.

Installing the Hardware 7
Chapter 2: Installing the Hardware
This chapter describes installing the NDShardware, including:
•Planning the installation
•Checking cables and connectors
•Sample configurations
Overview
Installing the NDS hardware includes the following steps:
1. Plan the installation
2. Connect the NDS port server to your network
The most common connection method is through the 10 BaseT RJ-45 connector (which is
labeled LAN) to your Ethernet LAN, using a standard straight-through Ethernet cable to
a hub/switch.
3. Connect your peripheral device(s) to the NDS port server
Attach each peripheral device (e.g., flow computer, printer, modem) to a serial port
( the DB-9 connector).
4. Plug the AC power supply adapter into the NDS
Planning the installation
Before installing the NDS remote communications server, consider the following:
•How will you configure your network—what types of devices will you connect and
where will they be located? Identify the distances at which each device will be located
from the NDS server.
•Verify that the locations selected for devices do not exceed cable specifications.
•Is there an acceptable source of AC power available near each device’s proposed
location?

NDS Panel Connectors8
NDS Panel Connectors
The following figures show the connectors and LED locations for the NDS/1000 models.
There are:
•three, four or six LEDs on the top of the unit
•one, two or four DB-9 or RJ-45 serial ports
•one RJ-45 Ethernet port
Top - LEDs

The Status LED indicates the overall status of the device. The Serial Port LED(s) indicate the
status of each serial port. The Ethernet LED indicates the status of the Ethernet
connection(s). For information on interpreting the LED color and pattern displays, see
Troubleshooting.
The reset button can be used to reboot the unit or to restore the factory default configuration
on the unit. Depressing and releasing the button will reboot the unit.
Depressing and holding the "Reset" button in for about 5 seconds will restore the default
(factory) configuration to the unit and then reboot the unit.

IEPS-1000 DB-9 Serial Operation
The IEPS-1000 with DB-9 serial connector uses an EIA-232 data terminal equipment (DTE)
pinout. Table 2-1 lists the pinouts of the DB-9 port used for EIA-232 serial communications.

powered on or may be used for flow control
5 GND Signal ground

powered on or may be used for flow control

Table 2-1: EIA-232 DB-9 Pinouts
Figure 2-2, Figure 2-3, and Figure 2-4 show cable diagrams for three common configurations.
The cable shown in Figure 2-3 may be used to connect modems to the NDS/1000. Modems
should be configured to switch their carrier detect signal (CD) on and off in response to
making and breaking telephone connections. This insures that the NDS/1000 terminates
user sessions when they disconnect. The cable shown in Figure 2-4 can be used to connect a
DB-9 terminal (or standard PC COM) port directly to the NDS/1000. The DB-9 to DB-9
terminal cable diagrammed in Figure 2-4 is a standard NULL modem connector, readily
available in retail outlets. DB-9 to DB-9 modem cables (not diagrammed) require no special
pinouts and use a straight-through cable. A 3-wire cable is shown in Figure 2-5.

The IEPS-1000 does not require the use of all 9 wires. Only the RX, TX, and GND signals are
essential. DTR/DSR and RTS/CTS are only necessary for flow control. DCD (pin 1) is
normally not required and RI (pin 9) is only required for modems that need a ring indicator.

Table 2-6: EIA-232 RJ-45 Pinouts
To connect your EIA-232 device to the serial port of an IEPS-1000 , you need to determine
whether the device connector wiring follows the standard for data terminal equipment
(DTE) or for data communication equipment (DCE). In general, modems are wired as DCE
devices and all other devices are wired as DTE; however, some equipment manufacturers
may deviate from the standard. The manual for your device will contain information on the
pinouts for the device. Figure 2-7 through Figure 2-10 show cable diagrams for the most
common configurations. Figure 2-11 shows a minimal cable using 3 wires.
The cable shown in Figure 2-7 or Figure 2-8 may be used to connect most ASCII terminals or
serial printers to IEPS-1000 serial ports. The cable shown in Figure 2-9 or Figure 2-10 may be
used to connect modems to the IEPS-1000 . Modems should be configured to switch their
carrier detect signal (CD) on and off in response to making and breaking telephone
connections. This insures that the IEPS-1000 terminates users’ sessions when they
disconnect. Figure 2-11 shows a 3-wire cable.

Figure 2-11: RJ-45 to DB-25 3-Wire Terminal Cable
RJ-45 to DB-25 or DB-9 adapters may be used with RJ-45 cables to create the cable
configurations shown in Figure 2-7 through Figure 2-11. In most cases, you use “straight
through” RJ-45 cables. If you use “crossover” RJ-45 cables, the RJ-45 pins will be reversed.
Figure 2-12 and Figure 2-13 illustrate the difference between the two types, when
constructed with flat 8-conductor wire.

Ethernet LAN
The NDS is connected to your LAN using an Ethernet port. The Ethernet port on the NDS is
a standard 10 BaseT RJ-45 jack. It can be connected to an Ethernet hub/switch via a
standard, straight-through Ethernet cable.

Starting the NDS18
Starting the NDS
When the NDS is powered up, the LEDs will flash to indicate normal operation. The
following LED colors and patterns will be displayed during normal startup, if no errors are
detected.
•Status LED – initially this LED will be yellow, but will quickly turn green. If the status
LED is solid green, then the NDS doesn’t have a permanent IP address and is trying to
obtain one from a DHCP server. If the LED is blinking green, it means the NDS has
obtained an IP address and is ready to use. Red indicates a fatal error.
•Ethernet LED – this LED will either be off, green or blinking green/yellow. A green
LED means that a good Ethernet link has been established and the unit is on the
network. The LED will blink green/yellow to show network activity.
•Serial port LEDs – these LEDs will normally be either yellow or green. Yellow indicates
a port that is not in use. Green indicates a port that is in use. The green LED will blink
when data is transmitted or received. It will blink 2 times per second when data is
continuously transmitted or received.
If any of the LEDs turn red, an error condition was detected. For a full description of the
LED patterns, see Troubleshooting.
