Overview 3
Chapter 1: Overview
The NDS port server 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 one or more PCs to
share expensive peripherals or to access peripherals that are located elsewhere on the local
or remote network.

Using the NDS6
Using the NDS
Using the NDS requires three steps:
1. Hardware installation
2. Configuration
3. Operation
Hardware installation is documented in this manual.
Refer to the NDS Administrator's Guide for configuration and operation.

Installing the Hardware 7
Chapter 2: Installing the Hardware
This chapter describes installing the NDS hardware, 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 10/100 Base-TX 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., cash register, card reader, modem) to a serial port
(one of the DB-9 or RJ-45 connectors).
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?

The Unit Status LED indicates the overall status of the device. The Port Status LEDs indicate
the status of each serial port. The LAN LED(s) indicate 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.

Connecting Devices to the NDS10
Connecting Devices to the NDS
The NDS serial ports may each be independently configured via software, to operate in RS-
232, RS-422 or RS-485 mode. The following sections describe the pinouts and cabling
options associated with these different modes.
NDS/5000 RS-232 Operation
The NDS/5000 server family uses a symmetrical EIA-232/RS-232 data terminal equipment
(DTE) pinout on the RJ-45 serial ports. Table 2-1 lists the pinouts of the RJ-45 ports used for
EIA-232 serial communications.
RJ-45
Pin
Number RS-232 Name Direction Signal Function
1 DCD I Signals module that remote device is
attached and powered on
2 RTS O Flow control, to enable remote device to
send data
3 SG Signal return (NOT chassis ground)
4 TXD O Serial data out, from NDS to remote device
5 RXD I Serial data in, from remote device to NDS
6 SG Signal return (NOT chassis ground)
7 CTS I Flow control, to enable NDS to send data on
TXD
8 DTR O Signals remote device that NDS is attached
and powered on
Table 2-1: EIA-232 RJ-45 Pinouts
To connect your EIA-232 device to the serial port of an NDS/5000, 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 2-2 through Figure 2-5 show cable diagrams for the most
common configurations. Figure 2-6 shows a minimal cable using 3 wires.
The cable shown in Figure 2-2 or Figure 2-3 may be used to connect most ASCII terminals or
serial printers to NDS/5000 serial ports. The cable shown in Figure 2-4 or Figure 2-5 may be
used to connect modems to the NDS/5000. 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/5000 terminates users’ sessions when they
disconnect. Figure 2-6 shows a 3-wire cable.

The NDS/5000 does not require the use of all 8 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. Figure 2-6 shows a minimal 3-wire cable using only RX (pin 5, data
in), TX (pin 4, data out), and GND (pin 3, ground).

Connecting Devices to the NDS14
RJ-45 to DB-25 or DB-9 adapters may be used with RJ-45 cables to create the cable
configurations shown in Figure 2-2 through Figure 2-6. 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 2-7 and Figure 2-8 illustrate the difference between the two types, when constructed
with flat 8-conductor wire.

NDS/6000 RS-232 Operation
The NDS/6000 port server family uses an EIA-232 data terminal equipment (DTE) pinout
on the DB-9 serial ports. Table 2-9 lists the pinouts of the DB-9 ports used for EIA-232 serial
communications.
