NET485 Quick Start 1
1. Quick Start
Follow this Quick Start guide to get your unit up and running fast.
WARNING: DO NOT CHANGE THE FIRMWARE UNLESS DIRECTED BY TECHNICAL SUPPORT
The NET485 kit contains the following items:
NET485 RS422/485 Serial to Ethernet Adapter
CD with NET485, Device Installer, Comm Port Redirector, user guides and application notes.
1.1 Setup Steps
The setup procedure consists of the following steps:
1. Connect 5-24VDC to the power pins.
2. Install the Device Installer software. Run Device Installer and search for the NET485.
3. Change the configuration settings
a. assign a fixed IP Address
b. Set Configurable Pin 1 (CP1) to RS485_TXEN (this is already factory set)
c. Set RS485_TXEN Active Level to High (this is already factory set)
d. Set the Serial Protocol to RS485 –2 Wire (this is already factory set)
(or RS422/485 - 4 Wire if the option jumper is set to 422)
e. Set the Serial Port parameters to match your device (baud rate, parity, etc.)
f. Remove the RX Term and TX Term jumpers for short lines
The NET485 is factory set for RS485. You can change it to RS422 by changing the protocol for the port
setting. You can select Full or Half Duplex by changing the internal jumper J2. The factory default setting is
Half Duplex where pins 2 and 3 are connected.
J2

2 NET485 Quick Start
To change the jumper J2 to Full Duplex, open the case and locate the jumper J2. Move the jumper to pins 1
and 2 as shown in the drawing.

Figure 2 - J2 Setting for Full Duplex
Connect the Hardware
Connect your network Ethernet cable to the NET485 RJ45 jack. Do not connect directly to your PC. The
NET485 should be connected to a router or server.
Connect a 5-24VDC power supply to the NET485. The polarity for the terminals is shown on the label.
Verify the Green power LED is ON.
Note: Do NOT use RX Term and TX Term jumpers on short transmission lines. Remove these jumpers to remove the
120 Ohm resistors from the transmit and receive lines.
Note: See the Application Notes on the product CD for more information about networks and termination procedures.
Connect your RS422/485 device to the NET485 terminals.
Connect the wires like this for RS422/485 4-wire, full duplex.

1.3 Configure with Web Manager
Please see the Device Installer user manual for details on using the Web Manager. This section presents
some basic setup parameters necessary to get the unit operational.
You must configure the unit so that it can communicate on a network with your serial device. For example,
you must set the baud rate to match the baud rate of your device. You should also assign it a fixed IP address for
your network.
The unit’s configuration is stored in nonvolatile memory and is retained without power. You can change the
configuration at anytime. The unit performs a reset after you change and store the configuration.
1.3.1 Network Configuration
The unit’s network values display when you select Network from the main menu.
Manually assign an IP address to the unit and enter related network settings.
To assign an IP address manually:
1. Select Use the following IP configuration.
2. Enter the following (as necessary):
IP Address
Assign IP address in decimal-dot notation. The IP address must be
set to a unique value in the network. Example: 172.20.206.150
Subnet Mask
A subnet mask defines the number of bits taken from the IP
address that are assigned for the host part. Example:
255.255.255.0
Default Gateway
The gateway address, or router, allows communication to other
LAN segments. The gateway address should be the IP address of
the router connected to the same LANsegment as the unit. The

6 NET485 Quick Start
gateway address must be within the local network.
Auto Negotiate
SettoAutoNegotiate.Withthisoption,theEthernetportauto-
negotiates the speed and duplex with the hardware endpoint to
whichit is connected. This is the default.
4. When you are finished, click the OK button.
5. On the main menu, click Apply Settings.
1.3.2 Channel 1 Configuration
The Channel 1 configuration defines how the serial port responds to network and serial communication.
To configure the channel’s serial settings:
1. On the main menu, click Serial Settings (under Channel 1) to display the Serial Settings window.
2. In the available fields, enter the following information:
Port Settings
Protocol
Must be RS485 2-wire OR RS422/RS485 4-wire
Flow Control
Flowcontrol manages data flow between devices in a network to
ensure it is processed efficiently. Too much data arriving before a
device is prepared to manage it causes lost or retransmitted data.
None is the default.
Baud Rate
The unit and attached serial device, such as a modem, must agree on
a speed or baud rate to use for the serial connection. Valid baud rates
are 300, 600, 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600,
115200, 230400, 460800, or 921600.
Data Bits
Indicates the numberof bits in a transmitted data package.
The default is 8.
Parity
Checks for the paritybit. The default is None.
Stop Bits
The stop bit follows the data and paritybits in serial communication.It
indicates theend oftransmission.The default is 1.
Pack Control
Enable Packing
The standard algorithm is optimized for applications in which the unit is
used in a local environment, allowing for very small delays for single
characters, while keeping the packet count low.
Enable this option if you have problems sending small packets of data.
Idle Gap Time
Select the maximum time for inactivity. The default time is 12
milliseconds.
3. When you are finished, click the OK button.
4. On the main menu, click Apply Settings.
