Using the Click 301

The Click 301 serial to Ethernet converter changes half-duplex two-wire RS-232 and RS-485 communication to

Ethernet and vice versa. Use this device in a cabinet to transfer data from a sensor to your computer or trac

operations center via a wired network connection.

Physical Features

The Click 301 has several communication ports, as well as features for conﬁguration (see the ﬁgure below).

Communication Ports

The back of the Click 301 features a 5-position connector that plugs into a T-bus connector and provides power

and RS-485 communication to the device. It also passes RS-485 communication from the module to all other

devices on the T-bus.

The top of the device has a pluggable screw terminal block that features -485, one +485 and two ground screw

terminals for wiring RS-485 communication. This screw terminal block can be removed for easy preinstallation

wiring. It will not be necessary to wire RS-485 through the screw terminal block if the device is connected to a

T-bus with uninterrupted RS-485 communication.

The front of the Click 301 features a DB-9 connector for RS-232 communication. A straight-through cable can be

used to connect from this port to a computer so that the device can be conﬁgured using Click Supervisor. The

front of the device also has an RJ-45 jack for Ethernet communication.

Any data on one port will be transmitted simultaneously on all other ports.

Conﬁguration Features

The faceplate of the Click 301 has three activity indicator LEDs:

■ PWR (red) lights up when the device has power.

■ TD (yellow) lights up when the device is transmitting data.

■ RD (green) lights up when the device is receiving data.

The LEDs are also used to indicate operation modes, which will be discussed in the On-device Conﬁguration

section of this document.

The faceplate also has a push-button labeled Mode Switch, which is used to cycle the Click 301 through operation

modes. This will be discussed in the On-device Conﬁguration section of this document.

On-device Conﬁguration

The Click 301 can be conﬁgured using the push-button on the lower part of the faceplate. Press and hold the

push-button to cycle through the dierent operation modes; release the button when the desired mode is

reached. A quick press and release of the push-button will exit out of any mode and return the unit back to normal

operation. The table below and the following sections describe the dierent operating modes.

Mode LED Deﬁnition

Autobaud Green (solid) To autobaud the Click 301, press the push-button, then release when the green LED turns on.

Reset Red (ﬂashing) To reset the Click 301 to factory defaults, press the push-button, then release when the red

LED is blinking.

Autobaud (green solid)

The Autobaud mode is used to match baud rates with an external device. By default, the device will attempt to

match baud rates with a SmartSensor on the bus; however, the device can be conﬁgured to autobaud with any

device that supports a serial interface.

While the device is autobauding, the green LED will be on while the red LED blinks. The autobaud was successful

if the red LED stays on and the green LED turns o. If the autobaud is not successful after a few minutes of trying,

the red and green LEDs will stay on indeﬁnitely. In the case of a failed autobaud, push the push-button once to

return the device to its normal state.

Note. On certain devices, the yellow LED may replace the green LED in the autobaud process—that is, the yellow

LED will come on to select the autobaud process, the yellow LED is on during the autobaud process, etc.

Factory Reset (red ﬂashing)

The Factory Reset operation will erase all user-conﬁgured ﬁelds, meaning that after the reset, the Click 301

may have to be reconﬁgured to work properly in its current application. If a device is not responding and

3 of 13WX-501-0531 • 01.22

not communicating, resetting the device may ﬁx the problem. Once the device is responding, restore the

conﬁguration needed for its current application.

To reset the Click 301 to factory defaults, release the push-button when the red LED begins ﬂashing. The red LED

should blink slowly, then the green and yellow LEDs will ﬂicker. When the red LED glows solid, the module has the

original factory conﬁguration.

Computer Conﬁguration

The Click 301 can be conﬁgured more exactly using the Click Supervisor software. See the knowledge base

article 0514 Installing and Using Click Supervisor for instructions on how to download and install Click Supervisor

and how to connect to your device using the software.

The Click 301 can be conﬁgured using one of three drivers (see the ﬁgure below).

Which driver you use will depend on what you need to use the device for. The ﬁrst two drivers are known as

application drivers and are used to set the Click device to work in speciﬁc applications. Use the list below to ﬁnd

the appropriate driver for your application:

■ If you intend to connect from your TOC to the Click 301 to a sensor, use the SmartSensor driver.

■ If you intend to connect from your TOC to a Click 301 to another Click 301 to the sensor, use the Point to Point driver.

To see advanced settings, use the Expert driver. This driver, which exposes every available ﬁeld for the Click 301,

should only be used under the direction of Wavetronix Support.

After you have made conﬁguration changes on a driver and saved it to the Click device, the word “current” will

appear after that driver to indicate the driver that is currently loaded onto the device.

Note. Some settings appear on multiple drivers. Changing one of those settings on any driver and saving them to

the Click device will change that setting on all other drivers it appears on.

The Backups option can be used to read conﬁgurations that have previously been saved to ﬁle.

Application Drivers

The two application drivers have very similar settings and ﬁelds; the only important dierences are found in the

Setup tab. Under the Setup tab, you can change the settings aecting the setup of the device and sensor (see the

ﬁgure and table below).

autobauding.)

The Ethernet > General > Network tab allows you to conﬁgure network settings (see the ﬁgure and table below).

8 of 13WX-501-0531 • 01.22

Setting Description

Local IP Lets you view and change the IP address currently assigned to the device.

Local TCP Port Lets you view and change the IP port currently assigned to the device. Each Click 301 defaults to

10001.

Subnet Mask Deﬁnes the number of bits taken from the IP address that are assigned for the host part.

Gateway IP Lets you view and change the gateway IP address. The gateway address should be the IP address

of the router connected to the same LAN segment as the unit. The gateway address must be within

the local network.

Remote IP Allows you to enter the IP address of the Click 301 that the Click 301 you’re conﬁguring should

connect to. Each Click 301 defaults to a remote IP address of 172.16.0.14.

Remote TCP Port Allows you to enter the port of the Click 301 that the Click 301 you’re conﬁguring should connect to.

Each Click 301 defaults to a remote port of 10001.

Auto Increment Increments the local port number for new outgoing connections automatically. The range of auto-

incremented port numbers is 50,000 to 59,999 and loops back to the beginning when the maximum

range is reached. Only use this automatic port increment feature to initiate a connection using TCP.

The Ethernet > General > Server tab allows you to conﬁgure server settings (see the ﬁgure and table below).

Setting Description

Telnet Password Allows you to enter the password required for Telnet access.

ARP Cache Timeout Deﬁnes the number of seconds (1–600) before the device refreshes the ARP cache.

9 of 13WX-501-0531 • 01.22

TCP Keepalive Deﬁnes how many seconds the unit waits during an inactive connection before checking its

status. If the unit does not receive a response, it drops that connection. The value can be

between 0 and 60 seconds. 0 disables keepalive. The default setting is 45.

Monitor Mode Disable Allows you to disable entry into the monitor mode using the ‘yyy’ or ‘xx1’ key sequence at

startup. This ﬁeld prevents the unit from entering monitor mode by interpreting the stream of

characters that are received during the device server’s initialization at startup.

CPU Performance (High) Sets the device to high performance. High performance is 88 MHz, while regular is 48 MHz.

The high performance setting requires more energy.

DHCP Name Lets you enter the name of the host on the network providing the IP address.

HTTP Port Allows the conﬁguration of the web server port number. The valid range is 1–65535. The

default port is 80.

The Ethernet > Channel > Connect tab deﬁnes how the unit makes a connection (see the ﬁgure and table below).

Setting Description

Incoming Connection Allows you to conﬁgure how the device reacts to incoming connections over the network.

Never rejects all external connection attempts.

Accept DTR accepts external connection requests only when the Modem Control In input is

asserted; this setting cannot be used with Modem mode.

Accept All is the default setting and accepts any incoming connection when a connection is not

already established.

Response Lets you set character response. When this is set to Character, a single character is transmitted

to the serial port when there is a change in connection state:

C= connected

D= disconnected

N= host unreachable

The IP address of the host connecting to the CoBos device will be provided when you use

verbose mode. This option is overridden when the Active Start Modem Mode or Active Start

Host List is in eect. The default setting is Nothing.

10 of 13WX-501-0531 • 01.22

Startup Allows you to conﬁgure active startup settings.

No Activity, the default, does not attempt to initiate a connection under any circumstance.

Any Char attempts to connect when any character is received from the serial port.

Active DTR accepts external connection requests only when the Modem Control In input is

asserted.

Speciﬁc Char attempts to connect when it receives a speciﬁc start character from the

serial port. The default start character is a carriage return. To change the character, see the

Disconnect tab.

Manual Connect attempts to connect when directed by a command string received from the

serial port.

Autostart automatically connects to the remote IP address and remote port speciﬁed when the

ﬁrmware starts.

Modem Mode causes the unit to present a modem interface to the attached serial device. It

accepts AT-style modem commands and handles the modem signals correctly.

Input Buer Allows you to choose circumstances under which the input buer will be ﬂushed.

On Active clears the input buer when a connection is initiated from the device to the network.

On Passive clears the input buer when a connection is initiated from the network to the

device.

At Disconn. clears the input buer when the network connection with the device is

disconnected.

Output Buer Allows you to choose circumstances under which the output buer will be ﬂushed.

On Active clears the output buer when a connection is initiated from the device to the

network.

On Passive clears the output buer when a connection is initiated from the network to the

device.

At Disconn. clears the output buer when the network connection with the device is

disconnected.

The Ethernet > Channel > Disconnect tab determines the conditions under which the unit will cause a network

connection to terminate (see the ﬁgure and table below).

11 of 13WX-501-0531 • 01.22

Setting Description

Disconnect Mode Allows you to set conditions under which the device should drop a connection.

Ignore DTR, the default, indicates that the Modem Control In doesn’t aect the

connection.

DTR Drop sets the network connection to or from the serial port to disconnect (drop)

when Modem Control In transitions from an asserted state to not asserted state.

Start Character Provides a place to enter the start character that is used to signal the active startup

function (found under the Connect tab) to attempt to connect.

Telnet Mode Enables Telnet mode.

Port Password Enables the use of a password on the serial port.

CTRL-D Disconnect Drops the connection when Ctrl-D or Hex 04 is detected. Both Telnet Com Port Cntrl and

Check EOT (Ctrl+D) must be enabled for Disconnect with EOT to function properly. Ctrl+D

is only detected going from the serial port to the network.

Hard Disconnect Closes the TCP connection even if the remote site does not acknowledge the disconnect

request.

Inactivity Timeout Sets the amount of time there can be no activity on the serial line before the device drops

the connection.

Telnet Name/Port Password Lets you enter either the Telnet name you’re using or the password for the serial port,

depending on which of those two boxes—Telnet Mode or Port Password—is checked.

The Ethernet > Channel > Packing tab allows you to conﬁgure packing settings, as well as to set other options

(see the ﬁgure and table below).

Setting Description

Packing Algorithm Enables packing, which deﬁnes how long the unit should wait before sending accumulated characters.

Idle Time (ms) Allows you to set the maximum time for inactivity.

Trailing Chars Lets you select the number of bytes to send after the end-of-sequence characters. The default is None.

Send Immediate Causes the module to send immediately after recognizing the transmit condition (sendchar or

timeout). If it is not set, any characters already in the serial buer are included in the transmission

after a “transmit” condition is found.

Send Char 2-Byte Causes the device to interpret the sendchars as a 2-byte sequence; if this option is not enabled,

the module interprets them independently.

12 of 13WX-501-0531 • 01.22

Send Characters Lets you enter up to two characters in hexadecimal. If the module receives a character on the

serial line that matches one of these characters, it sends the character immediately, along with any

awaiting characters, to the TCP connection. This action minimizes the response time for speciﬁc

protocol characters on the serial line (for example, ETX, EOT).

UDP Datagram Enables the use of UPD datagrams. This option cannot be changed here; it is enabled when you

open one of the two point to multipoint drivers and save that driver to the device.

The Ethernet > Hostlist tab allows you to set up and use a host list. When the host list is enabled, the Click 301

scrolls through the host list until it makes a successful connection to one of the addresses. After a successful

connection, the unit stops trying to connect to any others. If this connection fails, the unit continues to scroll

through the table until the next successful connection.

The host list supports a minimum of 1 and a maximum of 12 entries. Each entry contains an IP address and a

port number. The host list is ﬂowed onto three third-level tabs. If you need to enter more than the three host

IP addresses on the ﬁrst screen, go to the IP 4-9 and IP 10-12 third-level tabs. The three third-level tabs below

Ethernet > Hostlist allow you to conﬁgure the hostlist (see the ﬁgure and table below).

Setting Description

Hostlist Enable Enables the use of the host list.

Retry Counter Lets you set the number of times the module should attempt to retry connecting to the host list.

Retry Timeout Allows you to enter the duration (in seconds) the module should try to make a connection to the host

list before abandoning the attempt.

Host IP Address Lets you enter the host’s IP address.

TCP Port Allows you to set the target port number.

Under the Diagnostics tab, you can run diagnostics on your device (see the ﬁgure below). Click the General or

Ethernet buttons to run diagnostics on the items listed below each button. If a problem is detected, the program

will display a red square next to the item in question. If no problems are detected, a green circle will appear.
