Configuration Notes
1. The Modbus/TCP protocol contains a “Unit ID” field to identify multiple Modbus slave devices that are accessible at a single IP address.
When the Modbus/TCP command contains a Unit ID, the Modbus Gateway can pass the Unit ID to Modbus serial devices, which allows
multiple serial devices to be linked with a Modbus Gateway. When Auto Slave ID is enabled, a unit ID will be assigned automatically. If
the Auto Slave ID is disabled, a unit ID (any number between 1 and 247) must be manually assigned in the Slave ID field.
2. When the Modbus serial protocol is set to Modbus/RTU, the Serial Server is ready to receive connection requests from Modbus/TCP
master devices. Each message packet is determined by a character timeout. An incorrect character timeout may cause a CRC (Cyclic
Redundancy Check) checksum error. Modbus ASCII slave mode functions the same as Modbus/RTU slave mode, except that the data
format is Modbus/ASCII.
3. The Modbus/TCP Exception is in effect when the Modbus Gateway connects a Modbus/TCP Master with Modbus serial slave devices.
When the Modbus Gateway cannot get a response from Modbus serial devices, the Modbus serial protocol will not respond to the master
device. However, the TCP protocol has a longer waiting time, which could cause a network traffic problem for Modbus/TCP. For this
reason, the Modbus Gateway can automatically send a Modbus exception code 16 to the Modbus/TCP master device when there is not
response from the Modbus serial slave devices, thereby making overall network communication much more efficient.

Section 2: Hardware Installation
Install the TROY Serial Server (for wired and wireless models)
Follow the steps below to install the TROY Serial Sever. In most cases, the Serial Server’s factory default
settings should be sufficient for most serial connections; however, some of the configuration settings may
have to be changed for your particular installation. The TROY Serial Server can be wall mounted, set on
the desktop, or mounted using the optional DIN rail kit (available from TROY).
1. Before attempting to install the TROY Serial Server, make sure you have installed and set up your
serial device as described in the documentation that came with the device.
2. Write down the 12-digit MAC (Media Access Code) address printed on the label located on the
bottom of the Serial Server (for example: 004017023F96). You may need this number in order to
configure the Serial Server.
3. Connect the Serial Server to your serial device using a standard PC-compatible 9-pin (DB-9) serial
cable for RS-232 type devices (refer to Appendix A for pinout descriptions). A custom cable may be
required for RS-422 and RS-485-type serial devices. For RS-422/RS-485-type devices, a 120-ohm
terminating resistor may be required at the receiving end of a differential pair if the device is at the
end of the cable (refer to Appendix C for detailed information).
4. Plug the Serial Server power supply adapter into a suitable AC receptacle, and then plug the power
supply cable into the Serial Server. The Serial Server will run through a sequence of power-up
diagnostics for a few seconds.
If the Serial Server is operating properly, the LEDs will blink momentarily and then go out, the
yellow and green LEDs will illuminate if the wireless network is active, and the orange LED
will illuminate, indicating the device is receiving power (refer to page 1-4 for detailed LED
status descriptions).
The unit powers up in the Normal mode, which provides for connection from the network to
device(s) connected to the serial port of the Serial Server.
If the orange LED blinks continuously in a regular pattern, a problem exists. If this is the
case, try powering the unit OFF and then ON again. If the problem persists, refer to the
Troubleshooting section in this User’s Guide.
5. Connect the Serial Server to your network through a switch or hub using a category 5 (CAT5)
Ethernet cable. The Serial Server’s IP address must be configured before a network connection is
available. If your network offers DHCP (Dynamic Host Configuration Protocol), the Serial Server will
automatically search for a DCHP server upon power up and obtain an IP address. If your network
does not offer DHCP, a static (fixed) IP address must be assigned (see your system administrator for
assistance). In most cases, a fixed IP address is preferred because a DHCP server may not always
assign the same IP address to the Serial Server when the Serial Server is powered ON.
The Serial Server also supports the following protocols. See your system administrator for help.
arp
rarp
BootP
NOTE: The IP address must be within a valid range, unique to your network, and in the same subnet as your PC
(refer to page A-1 for a list of TCP port connections).
NOTE: For wireless Serial Servers, if a wired connection is established to the unit, the wireless link will be disabled.

Configuring the Serial Server via an Ethernet Connection
For Microsoft Windows operating systems, the TROY ExtendView Utility is the recommended method of
configuring one or more Serial Servers on your network. Once the Serial Server obtains an IP address
(occurs automatically when the unit is powered ON and connected to a DHCP netowrk), the ExtendView
Utility’s auto-discovery feature will search for and locate all Serial Severs on the network and then display
the IP address for each discovered Serial Server.
USING THE EXTENDVIEW UTILITY TO CONFIGURE THE SERIAL SEVER (WINDOWS OPERATING SYSTEMS):
1. Start the ExtendView Utility by clicking on Start, Programs, TROY GROUP, and then ExtendView.
2. When the Welcome screen appears, click on Next, choose any name for your View Name, select
Automatically create a view with default settings (or configure the view to your preferences), and
then click on Finish.
3. Right-click on the Serial Server that you want to configure from the displayed list, and then left-click
on Configuration. The default Serial Server name is TWC_xxxxxx (where xxxxxx is the last six digits
of the MAC address from the label located on the back of the Serial Server).
4. If you are using TCP/IP (recommended for Windows) and you do not have a DHCP server (see note
below), you will need to manually assign a valid IP Address (if you are not sure what IP address is
valid, ask your network administrator), and then click on OK.
5. Configure the 802.11b wireless settings (for wireless models only). To operate on an 802.11b
network, the Serial Server configuration must be set to the same configuration as your wireless
network to allow the Serial Server to communicate over your wireless network. All nodes of a
wireless network need to have the same settings to allow communication between the devices.

NOTE: If you are using DHCP on your network, the Serial Server should have acquired valid IP settings at this point
and no further configuration is necessary. However, for most installations, a static IP address is preferred. If your
DHCP server does not allow the Serial Server to keep its assigned IP address permanently, then you must manually
assign an IP address. In this case, use a static IP address outside the range reserved for DHCP (see your DHCP
server documentation for details). To assign a static IP address, right-click on the Serial Server in the menu, and
then select Configuration. On the TCP/IP tab, under IP Address Resolution, select Set Permanent, and assign a valid

Document #40179-120 Rev. X5 3-3
USING THE WEB BROWSER INTERFACE TO CONFIGURE THE SERIAL SERVER (NON-WINDOWS SYSTEMS):
To configure the Serial Server using non-Windows operating systems (e.g., Unix systems), a standard
web browser (e.g., Internet Explorer or Netscape Navigator) can be used to access the Serial Server’s
embedded Web (HTTP) server pages, which contain the Serial Server’s configuration options. No
additional software is required.
1. Ensure your PC is connected and has access to your network.
2. Connect an available Ethernet cable from your network hub to the Serial Server. Ensure the Serial
Server is powered ON.
3. Connect the Serial Server to the desired serial device, and ensure that the device is powered on and
ready. If the Serial Server is connected to a serial device that cannot display or print ASCII
characters, then it is recommended that another serial device capable of displaying or printing ASCII
characters be temporarily connected to the Serial Server in order to view the IP address assigned by
the DHCP server to the Serial Server.
4. With the serial device and Serial Server switched on and ready, press the Test button on the Serial
Server to send the Serial Server’s configuration data to the connected serial device. The serial
device should display or print the current IP address assigned to the Serial Server by your network
DHCP service. If your network does not use DHCP, then the Serial Server will have the default IP
address of 192.0.0.192. In any case, your computer must use an IP address other than the one used
by the Serial Server in order to establish a connection between the two devices.
5. Configure the 802.11b wireless settings (wireless Serial Servers only). To operate on an 802.11b
network, you must set the Serial Server’s wireless mode (ad-hoc or infrastructure), SSID channel,
data rate, and security settings (WEP keys, 802.1x settings, etc.) to the same configuration as the
wireless network you want the Serial Server to communicate on. All nodes of a wireless network
need to have the same settings in order to communicate with each other.
6. From the host computer, open a standard web browser (e.g., Internet Explorer, Netscape Navigator),
enter the IP address of the Serial Server into the address bar of the web browser, and then press
Enter. The Web Browser Utility screen will be displayed. Click on the Login menu selection, enter
the password (default is ACCESS), and then click on Submit. The main screen will be displayed,
allowing you to configure the settings of the Serial Server. The menu selections are displayed on the
left side of the screen, and the individual settings are located at the top of the screen.

NOTE: Be sure to set your PC back to its original wireless settings after you finish configuring the wireless Serial
Server.
NOTE: It is not necessary to change your computer’s settings if you are configuring the print server’s settings via an
Ethernet connection.
First-Time Configuration of the Wireless Serial Server Using 802.11b
(wireless models only)
Although the Serial Server can be configured using a wireless connection, it is recommended that the
Serial Server be initially configured using a wired connection as described on the previous pages. The
Serial Server’s wireless network interface supports all modes of 802.11b at 1, 2, 5.5, and 11 Mbps. The
wireless network is only active if the Serial Server is not connected to a wired network. If a wired link is
established to the Serial Server, the wireless link is automatically disabled. To configure the wireless
Serial Server for the first time from a computer via an 802.11b wireless connection, you will need to
temporarily change your computer’s settings to match the default settings of the Serial Server as follows:
Wireless Mode: Ad-Hoc (sometimes referred to as Peer-to-Peer)
Channel: 11
SSID (or wireless network name): serserv
You should now be able to configure your Serial Server using either the ExtendView Utility or the Web
Browser Interface as described in the previous sections.
In addition to the standard 802.11 WEP (Wired Equivalency Privacy), TROY provides additional wireless
security options (refer to the security addendum for detailed information).

Verifying the Serial Server’s Connection to a Serial Device
1. Verify that both the Serial Server and the connected serial device are powered on and ready, and that
a serial cable is properly connected between the Serial Server and serial device (i.e., transmit signal
output from the Serial Server going to the receive signal input on the serial device, ground leads
connected together, etc.).
2. Verify that the Serial Server’s port settings (i.e., baud rate, flow control, character bit size, parity, etc.)
exactly match the settings of the connected serial device’s port.
3. If the serial device connected to the Serial Server is able to display or print ASCII characters (such as
terminal emulator or serial printer), then communication between the devices can be verified by
pressing the Test button on the Serial Server for about one second (but less than five seconds),
which will initiate the output of configuration data from the Serial Server to the connected serial
device.
If communication has been successfully established between the two devices, the serial device
should be able to display or print the Serial Server’s configuration data.
If no data is displayed or printed, verify that both devices are powered ON, are properly
connected using a suitable serial cable, and are using compatible serial port parameters. The
two most common serial communication problems are due to the either the cabling and/or
mismatched serial port parameters.
If you are unable to establish a working serial connection between the Serial Server the connected serial
device, refer to the troubleshooting section in this User’s Guide. For additional troubleshooting
information, refer to the troubleshooting section in this user’s guide, or contact TROY Technical Support
at (800) 332-6427, or visit the TROY web site at http://www.troygroup.com, or send an e-mail to
technicalsupport@troygroup.com. Customers outside the United States, please call (304) 232-0899.
European customers, please call +49 (0) 7032-9454-21, or send an e-mail to support@troygroup.de for
assistance.
NOTE: Before attempting to use the Serial Server, you must verify the connection between the Serial Server and the
connected serial device. If this connection is not working, you will not be able to send and/or receive data from the
connected serial device.
NOTE: If the Serial Server is connected to a serial device that cannot display or print ASCII characters, then it is
recommended that another serial device capable of displaying or printing ASCII characters be temporarily
connected to the Serial Server in order to verify the serial connection. After successful communication is verified
using the temporary serial device, reconnect the original serial device, making sure that the original serial device is
configured with serial port parameters that match the tested connection.

Changing the Serial Settings
In order to establish communication between the Serial Server and a serial device, the serial settings for
both devices must match. The serial settings can be changed using ExtendView (recommended), the
web browser interface, or the Serial Server’s internal configuration console (refer to the previous sections
for the installation and use of these utilities). Refer to page 1-5 for a list of factory default settings.
USING THE EXTENDVIEW UTILITY TO CHANGE
THE SERIAL SETTINGS:
1. Start the ExtendView Utility by clicking
on Start, Programs, TROY GROUP,
and then ExtendView.
2. From the main menu, click on Options,
and then click on Configuration.
3. Click on the Output Port tab, and then
click on the Serial Settings button.
4. After configuring the serial settings, click
on OK to continue.
Changing the Baud Rate
In some cases it may be necessary to change the baud rate of the serial sever in order to match the baud
rate of a particular serial device where the baud rate is fixed. Baud is a measurement of transmission
speed in asynchronous communication and represents the number of bits that are actually being sent
over the media, not the amount of data that is actually moved from one device to the other. The TROY
Serial Server supports baud rates from 300 to 460800 bps (refer to page 1-5 for the specific baud rates
supported). To ensure communication between connected serial devices, all other serial port parameters
(mode, character bits, parity, etc.) must be identical for each serial device.
Changing the Serial Port Protocol
The Serial Server’s serial port protocol (data transmission mode) can be changed to match the particular
characteristics of the connected serial device’s UART (Universal Asynchronous Receiver/Transmitter).
The TROY Serial Server supports the following serial port protocols. Each of these protocols is capable
of handling data transfer speeds of 1 Mbps or better.
Protocol Description
RS-232 an interface between data terminal equipment and data communications equipment employing
serial binary data interchange over a wired connection with a maximum range of 50 feet (16.5
meters).
RS-422 a data transmission system using balanced differential signals (voltages) to send serial binary
data over a wired connection with a maximum range of 4,000 feet (1.2 km).
RS-485 / RS-
485HD a data transmission system using balanced differential signals (voltages) to send serial binary
data over a wired connection with a maximum range of 4,000 feet (1.2 km). As many as 32
driver/receiver pairs can share a multidrop network (4-wire at full duplex or 2-wire at half duplex).
Many characteristics of the drivers and receivers are the same as RS-422.
Serial Server User’s Guide
Document #40179-120 Rev. X5 3-8
Using the Modbus Protocol
Modbus is a widely used industrial device communications protocol that provides “client/server”
communications between devices connected on different types of buses or networks. The TROY Serial
Server supports the Modbus serial line version of the protocol used for communicating with many types of
industrial devices (e.g., instruments, meters, controllers, switches, etc.) over a serial-to-Ethernet
connection. In general, the TROY Serial Server operates as a transparent device between the host
(master device) and the connected serial devices (slaves), sending and receiving data to and from one or
more slave units (up to a maximum of 32 slave serial devices). The Serial Server uses the RS-232 and
RS-485 serial port protocol (using a 9-pin connector) for Modbus communication.
Serial Transmission Modes
Two connection protocol options are available between the TROY Serial Server and the serial device:
RTU (Remote Terminal Unit) Mode – allows for greater character density, which allows for
better data throughput than ASCII mode. However, each message must be transmitted in a
continuous stream of characters.
ASCII (American Standard Code for Information Interchange) Mode – is used when the
physical communication link or the capabilities of the serial device do not allow conformance with
RTU mode requirements.
Typical Modbus Applications
Many traditional Modbus devices can talk over an RS-485-type serial port provided that the transmission
distance between the serial device and the TROY Serial Server does not exceed 4,000 feet (1.2 km).
When using the RS-232-type serial port, the connection between the TROY Serial Server and the serial
device cannot exceed 50 feet (16.5 meters), which is sufficient for short point-to-point communications.
Using the TROY Serial Server configured as a Modbus master device, up to 32 Modbus slave devices
can be placed on the same Modbus network using the RS-485-type serial port.
In a master/slave configuration, the master serial device will always initiate communication with the slave
devices, and the slave devices will never talk to each other. In unicast mode, the TROY Serial Server
can only address an individual slave at one time with each slave having a unique network address. In
this mode, when addressed by the master, each slave returns a reply to the master device. In broadcast
mode, the TROY Serial Sever can address all the slave units simultaneously; however, in this case, the
slave devices do not send a reply to the master device.
Changing the Modbus Settings
In order to establish communication between the Serial Server and a serial device using the Modbus
protocol, the Modbus settings for both devices must be compatible. The Serial Server’s Modbus settings
can be changed using the TROY ExtendView Utility (recommended), the web browser interface, or the
Serial Server’s internal configuration console (refer to page 3-1 for detailed application use).

Section 4: Troubleshooting
Introduction
This section describes procedures for troubleshooting problems you may encounter with the TROY serial
server, and is divided into the following sections:
Installation Problems
Intermittent Problems
Protocol-Specific Problems
Troubleshooting Installation Problems
If you cannot access the connected serial device via the Serial Server, first check the network connection
and cabling.
Check the physical cabling to ensure all cables are plugged in (Ethernet and DB-9 serial cable).
If the appropriate LEDs are not illuminated, then there is probably a bad 10baseT or 100baseTX
cable, or the hub port is bad. If possible, try a different cable and hub port, or try connecting a
different device to the cable.
Verify that you using the correct values for both IP Address and Port Number. A common
mistake is to assume the TCP port number is the "device number" on the server.
If you are using a hub, verify that the hub port is operating correctly by trying the Serial Server on
a different port.
Troubleshooting Network Configuration Problems
If you are using TCP/IP, make sure that your computer and the serial server are on the same IP
segment or can reach each other with a PING command from the host. The IP address you
assign to the serial server must be on the same logical network as your host computers (e.g., if
your computer has an IP address of 192.189.207.3, the Serial Server should have an IP address
of 192.189.207.x, where x is an integer between 1 and 254), or you must properly configure your
router address to work with the serial server.
If your serial server is set to Auto or DHCP for obtaining an IP Address, it is possible that the
serial server’s IP address can change. Either configure your DHCP server to give the serial
server a permanent lease, or configure the print server to be on a STATIC IP address outside the
scope of the DHCP addresses.
The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP
address is correctly loaded into the TROY serial server (via the displayed or printed configuration
information or through the remote console), and make sure that no other nodes on the network
have this address (duplicate addresses are the biggest cause of TCP/IP connectivity problems).
If the IP address is not correct, then check whether the loading procedure was properly executed.
Also verify that the host computer and the serial server are either on the same subnet (for
example, if the serial server has a subnet mask of 255.255.255.0, the host must have the same
subnet mask) or that the router is properly configured to pass data between the two devices.
If the wrong IP address is loaded, check your network for file servers that have DHCP, BOOTP,
or rarp enabled, and make sure that these file servers are not set up to load IP addresses into the
serial server.
Serial Server User’s Guide
Document #40179-120 Rev. X5 4-2
Troubleshooting Windows Problems
If you are having trouble accessing the connected serial device through Windows, ensure you
can ping the TROY Serial Server using the DOS command PING ipaddress, where ipaddress
is the IP address of the TROY Serial Server. If you cannot ping the serial server, you will not be
able to access the serial device.
If you are running COM port emulation software and the software reports an error, verify that the
correct serial/IP COM port is being used when the application runs. Verify that your application’s
COM port settings have been changed to use the Serial/IP COM ports.
Troubleshooting Wireless Configuration Problems
Verify that your PC’s wireless adapter and/or access point is configured properly – note the
settings, paying special attention to the wireless mode, SSID or network name, WEP or security,
and IP address settings so you can configure your serial server to the same wireless settings.
Make sure you have a good wireless signal from your PC and from the serial server, that the
serial server is within range (90 meters or 300 feet), and that it is away from metal objects and
other devices that generate radio signals (like Bluetooth devices, cordless phones, and
microwave ovens).
Make sure your computer is set to infrastructure mode if you are connecting through an access
point, or ad-hoc (802.11) if you are connecting to the serial server without an access point. See
the documentation for your wireless adapter for details.
If you want to use WEP encryption or password protection for your wireless network, and your
wireless adapter or access point normally uses a password or passphrase instead of WEP, it
should allow you to enter 0x followed by a 10-digit key (for 40-bit or 64-bit WEP) or 26-digit key
(for 128-bit WEP) in hexadecimal format (0-9 or A-F).
If you are experiencing slow performance or are having intermittent problems connecting, try
changing the RF channel of your wireless network. The RF channel can be changed via the
ExtendView Utility or the web browser configuration utility for the serial server. See your wireless
adapter and/or access point documentation for more information. When changing the RF
channel, it is recommended that you select a channel that is at least three channels lower or
higher than any other wireless networks within range.

Appendix D: Alternate Power Source Configuration
The TROY Serial Server can be configured to use a +5 VDC input via Pin 9 on the DB-9 connector to
power the unit instead of using the supplied power supply module. To configure the serial server to
accept power via Pin 9, the serial server case must be opened, and the shunt at JP3 must be moved from
Pins 2 and 3 to Pins 1 and 2 (towards the +5 indicator). The voltage measured at Pins 9 and 5 must be at
least +4.8 VDC and not greater then +5.2 VDC. Minimum supply current is 800 mA and 500 mA for the
TROY wireless and non-wireless serial server, respectively. If Pin 9 is utilized for power, it is
recommended that shielded cable be used to minimize EMI (Electro-Magnetic Interference).
