Overview 3
Chapter 1: Overview
The iNS Industrial Network port Server provides communication between peripheral
devices and computers connected to a network. When the iNS 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 iNS 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.

Installing the Hardware 7
Chapter 2: Installing the Hardware
This chapter describes installing the iNS hardware, including:
•Planning the installation
•Checking cables and connectors
•Sample configurations
Overview
Installing the iNS hardware includes the following steps:
1. Plan the installation
2. Connect the iNS port server to your network
The most common connection method is through the 10/100 Base-TX RJ-45 connector to
your Ethernet LAN, using a standard straight-through Ethernet cable to a hub/switch.
3. Connect your peripheral device(s) to the iNS port server
Attach each peripheral device (e.g., PLC, card reader, modem, etc) to a serial port (one of
the DB-9 or screw terminal connectors).
4. Plug the AC power supply adapter into the iNS
Planning the installation
Before installing the iNS 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 iNS 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 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 iNS
The iNS 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.
iNS/3000 RS-232 Operation
The iNS/3000 port server family uses an EIA-232 data terminal equipment (DTE) pinout on
the serial ports. Table 2-1 lists the pinouts of the DB-9 and screw terminal ports used for EIA-
232 serial communications.
Pin
Number RS-232 Name Direction Signal Function
1 DCD I Signals module that remote device has a valid
connection
2 RX I Serial data in, from remote device to iNS
3 TX O Serial data out, from iNS to remote device
4 DTR O Signals remote device that iNS is attached and
powered on
5 GND Signal ground
6 DSR I Signals module that remote device is attached and
powered on
7 RTS O Flow control, to enable remote device to send data
8 CTS I Flow control, to enable iNS to send data on TX
9 RI I Ring Indicator (except on screw terminal connector)
Table 2-1: EIA-232 Pinouts
The screw terminal connectors for each port bring out the same signals as the DB-9
connectors with the exception of the RI signal that is only present on the DB-9. The screw
terminal pins are numbered left-to-right, 1 through 8.

Connecting Devices to the iNS10
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 iNS/3000. 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 iNS/3000 terminates user
sessions when they disconnect. The cable shown in Figure 2-2 can be used to connect a DB-9
terminal (or standard PC COM) port directly to the iNS/3000. 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.

Figure 2-4: DB-9 to DB-9 Terminal Cable
The iNS/3000 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.
Figure 2-5 shows a minimal 3-wire cable using only RX (pin 2, data in), TX (pin 3, data out),
and GND (pin 5, ground).

RS-422/485 Operation
Unlike RS-232, the RS-485 and RS-422 specifications do not have a standard set of pinouts.
In general, whenever you use RS-422/485 devices you will need to make custom cables. The
iNS pinouts for RS-422 /RS-485 mode are shown in Table 2-6.

8 RXA/RX- Input
9Notused
Table 2-6: DB-9 Pinouts for RS-422 and RS-485
RS-485 2-wire mode uses the same pinouts, but the receive and transmit pairs should be
externally shorted together in the connector (TXA shorted to RXA and TXB shorted to RXB).
Note that some RS-422 and RS-485 devices refer to the differential pair of signals that make
up the transmit and receive lines as “-” and “+“ instead of the standard “A” and “B”. In
most cases, the “-” signal corresponds to the “A” signal and the “+” signal corresponds to
the “B” signal, but some devices reverse this. Refer to the chapter on Using RS-422 and RS-
485 Devices for more information on wiring and using 2-wire and 4-wire RS-422/485
networks with the iNS.

Connecting Devices to the iNS14
Ethernet LAN
The iNS is connected to your LAN using an Ethernet port. The Ethernet port on the iNS is a
standard 10/100 Base-TX RJ-45 jack. It can be connected to an Ethernet hub/switch via a
standard, straight-through Ethernet cable.

Figure 2-7: Network Topology Example
The switch versions of the iNS have four 10/100 Base-TX Ethernet ports. These ports are all
interchangeable. Any port can be used to either connect to a hub/switch or to a network
device (auto MDI/MDIX).

Installing the Hardware 15
Starting the iNS
When the iNS 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 iNS 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 iNS has
obtained an IP address and is ready to use. Red indicates a fatal error.
•Ethernet LEDs – these LEDs will either be off or green. A green LED means that a good
Ethernet link has been established and the unit is on the network. The LED will blink
green to show network activity.
•Serial port LEDs – these LEDs will normally be either off or green. Off 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.
