2-5. Dip Switches
A double DIP switch allows the TRP-C32S to be placed into default/ Loop Back/Factory/console
Mode.
When all these switches are moved into the ON position, theTRP-C32S enters console Mode,
allowing configuration of the TRP-C32S from a PC running a terminal program such as
Hyper-terminal. When the TRP-C32S enters console Mode, the console Mode screen will
appear in the Hyper-terminal program window. The PC serial port configuration must be set
to 8-N-1 at 9600 baud rate.
When the DIP switches are switched to the ON OFF position, the TRP-C32S will work at internal
Loop back Mode, all data is sent back immediately.
When the DIP switches are switched to the OFF ON position, the TRP-C32S will revert to its
factory version firmware no matter what newer firmware has been upgraded.
When all of the DIP switches are switched back to the OFF position, the TRP-C32S will enter
default data Mode (RS-232, RS-422 or RS-485). Refer ,3

7-1-1.Searching LAN for TRP-C32S
Once TRP-C32S is connected to the LAN the TRP-C3X Manager software will search it and
display it in a window by name and IP address.
A. Select “TRP-C3X Manager” Utility in the program file menu. If the default location was
selected during the installation the program will be found under “Start/Programs/Trycom
/TRP-C3X” utility. As soon as the “TRP-C3X Manager” Utility opens it will initiate Searching
Server and after a few seconds the Serial Server List will display all (TRP-C32S/32/34) serial
servers on the network.
B. To manually initiate a search for servers, on the menu side bar select Searching Server button.
The Search Setup box will appear.
It provides two options for searching for servers on the network:
• Specify the IP address of the Serial Server.
• Search all reachable servers
Enter the IP Address assigned to the desired Serial Server or click Search all reachable servers,
click “OK”. The Searching window is shown until all active Serial Servers on the LAN are listed
in the Serial Server List window.

11
7-1-2.Configuring Server Properties
Highlight the serial server in the Serial Server List window and double click to open the
Server Properties window. The Server Properties window is used to configure and store the
Server configuration settings. Details for setting Properties are described in the next chapter.
After configuring as needed, click Update to store the configuration in the server and click
“Yes” to restart the server to make sure all settings are changed to conform to the desired
application.

12
Server Name
The server name is user configurable. It is recommended users with more than one TRP-C32S
connected to the LAN assign a new name to each. When the Manager software searches for
servers on the LAN it will display the server name allowing the user to distinguish between
TRP-C32Ss.
Serial Number
Each TRP-C32S has a unique serial number. This is fixed and cannot be changed.
Password
Entering a password activates a security feature on the serial server. Once a password is
entered it will be required to access the menu and make changes.
DHCP
DHCP servers are a part of numerous LAN management systems. The DHCP field has two
selections, “Enable” or “Disable”. Arrow to the desired selection and select enter.
When enabled, TRP-C32S will send a DHCP request to the DHCP server, which will assign a
dynamic IP address, netmask, and gateway to the TRP-C32S. If a DHCP server is not available
on the network the TRP-C32S will time out after 10 seconds and the default values will remain.
When DHCP is enabled, the IP address, Netmask and Gateway fields become inaccessible and
cannot be changed by the user.
IP Address
A static IP address can also be assigned in this section of the menu. A dynamic address
assigned by the DHCP server may change if the TRP-C32S looses the Ethernet connection or
power is removed. The host (client) communication software requests a connection to the
specific IP address of the serial server. If the DHCP reassigns a different IP address the software
will not be able to communicate with the hardware. It is recommended to use a static IP address.
A static IP address is permanent and will not change unless changed in the menu. In most cases
the network administrator establishes the static address to be used.
Netmask
The default LAN netmask is configured for a Class C address. This maybe reconfigured by the
user.
Gateway
The gateway IP address allows users to access the serial server from outside the LAN.

13
MAC Address
The MAC address is not adjustable. This is assigned in the factory. Every Ethernet device
manufactured has it own unique MAC address.
Version & Date
The currently loaded version of the firmware, and when it was released, are shown here.
Link Status
Link status automatically displays the type of Ethernet connection. It will either display 10 BaseT
or 100BaseTX in full duplex or half duplex. This will depend on the LAN, switches, hubs used in
the LAN topology.
Server Serial Port
This field indicates the number of the port for with serial server properties are currently being
displayed. Changing the number in this field will cause all the other fields to display the
properties for the specified port. Note, however, that before changing ports, any change to
properties must be updated (Saved) or the serial server will not retain them.
Baud Rate
The serial port baud rate on the TRP-C32S must match the serial baud rate of the connected
device unless using Virtual COM mode. In Virtual COM mode the software program will establish
serial settings.
Data/Parity/Stop
This setting will have to match the data format of the connected device unless using Virtual COM
mode. In Virtual COM mode the software program will establish serial settings.
Flow Control
The flow control setting must match the connected serial device unless using Virtual COM mode.
In Virtual COM mode the software program will establish serial settings.
Protocol
Select TCP or UDP protocol. If the application does not require a UDP connection, select TCP.
TCP guarantees reliable communication with error checking whereas UDP provides faster
transmission.
When UDP mode is chosen the Serial timeout, TCP alive timeout, Connection mode, Connection
at, Maximum connection and Remote IP address fields are replaced with the following three
fields: Destination IP address range, Port number and Source IP address range. In this mode the
server can be configured to broadcast data to and receive data from multiple IP addresses. Four
IP address range fields are provided.

14
Serial Timeout
Default is 0, or no timeout. Setting timeout to any value between 1 and 65535 seconds activates
it. If communications are idle for specified timeout value the serial server will reset and make
itself available for another connection.
TCP Alive Timeout
This monitors TCP activity. If TCP activity stops for the length of time specified in this field the
connection will be closed. This field can be set to any value between 0 and 255 minutes. If zero,
or no value, is entered into this field the server will not disconnect.
Connection Mode
The Connection mode field has three options, Server, Client and Client (no heartbeat). When
Client or Client (no heartbeat) is selected, the Connection at field automatically becomes active
(allowing the user to select Power up or Data arrival).
• When using the Virtual COM Port feature, select Server.
• When using a TCP or UDP Socket program, select Server.
• When using Paired Mode communication between two serial servers set up one as a Client
and the other as a Server.
• When connecting to a server that does not support Heartbeat, select Client (no heartbeat).
Delimiter HEX1 and Delimiter HEX 2
These two fields allow the user to enter two ASCII characters (in hex format) that delimit the
beginning and end of a message. When a message with both these delimiters is received at the
serial port, the data contained in the serial buffer is placed in an Ethernet packet and sent out the
Ethernet port. If only Delimiter 1 is set (Delimiter 2 is zero or blank), upon receiving Delimiter 1
the TRP-C32S will put all the data in the serial buffer in an Ethernet packet and send it out the
Ethernet port. If serial data greater than 1 kilobyte is received it will automatically be placed in an
Ethernet packet and sent out the Ethernet port.

15
Force Transmit
This field allows the user to set a maximum time limit between transmissions of data. The value
set in this field multiplied by 100 ms determines the Force Transmit time. When the elapsed time
reaches the time configured in this field, the TCP/IP protocol will pack the data currently in the
serial buffer into a packet and send it out the Ethernet port.
Port Status
This field indicates whether a serial port is connected to a server or by a client.
TCP/UDP Port
The TCP/UDP Port defines a communication port number. In all modes of operating, Virtual
COM, Direct IP, and Paired modes, both the TCP/UDP Client and server port settings must
match.
For example the Virtual COM defaults setting TCP/UDP Port # 4000. If the port # of the
TRP-C32S is changed to 4001, the Virtual COM TCP/UDP Port will have to be changed to 4001.
Serial Port Mode
This allows configuration of the serial server for the following modes of operation:
• Console – When this mode is selected and the server is updated, a PC running a
communication program such as Hyper-terminal can communicate with the
serial server via the Console Mode serial port (Port 1 on TRP-C32S),displaying
the Server Properties screen and allowing configuration of the server and its
ports.
• Upgrade – When this mode is selected and the server is updated, firmware can be uploaded
into the serial server via the Console Mode serial port or a virtual COM port
appeared to the number of the Console Mode serial port.
• Factory – When this mode is selected and the server is updated, it will revert the server to
its default configuration.
• RS-232 – When this mode is selected and the server is updated, the selected serial port
will become a RS-232 serial port on the server.
• RS-422 – When this mode is selected and the server is updated, the selected serial port
will become a RS-422 serial port on the server.
• RS-485 – When this mode is selected and the server is updated, the selected serial port will
become a RS-485 serial port on the server.

16
Connection At
When the Connection Mode field is set to Client or Client (no heartbeat), this field becomes
active, allowing the TRP-C32S (acting as a client) to connect to the server either on Power up or
on DataArrival (first character arriving).
Maximum Connection
This field allows the user to configure the Serial Server to have up to eight TCP connections.
Remote IP Address
This is a security feature that is activated when the IP address of the desired client is
programmed into the remote IP Address setting of the menu. This tells the TRP-C32S to
communicate with only the listed IP address and to filter out all other requests for connection.
The TRP-C32S is setup in the menu as a TCP or UDP server to us this feature.
The default setting is 255.255.255.255. It is recommended not to change this setting until the
application has been tested and is communicating properly. At that point the address filtering
feature of the TRP-C32S can be activated.
Update/Save
Server properties must be updated separately for each serial port. Updating varies slightly
depending on which of the four configuration user interfaces are used.
Updating the Server Properties in Manager Software
From the Server Properties screen, click the Update button to store the configuration settings for
the currently selected port. The “vcomui” dialogue box will appear indicating you must restart
the device before the new settings will take effect. Click Yes.
7-2 Using Console Mode
The console mode allows access to the TRP-C32S setup menu. This is one way to reconfigure
the default settings for the application. A serial connection is made between a COM port on the
PC and the TRP-C32S serial port A with a null modem cable. In console mode, the serial port
defaults to an RS-232 interface.

17
The TRP-C32S serial port default settings are, baud rate 9600, 8 data bits, no parity, and 1 stop
bit. Hyper Terminal should be used for this type of setup. Hyper Terminal’s serial settings are
configured the same as the mentioned default settings of the TRP-C32S and must be set to
VT100 emulation mode. The default settings are used only if they have not been changed
