WRC-4 Web Based Remote Control

INSTALLATION

INSTALLATION

Web Interface

The WRC-4 firmware supports an HTTP (Web) interface on TCP port 80 and is user
programmable. The default page contains a Java applet used to monitor and control
the WRC-4.

Information you’ll need to know

1 - An available Static IP address to assign to the WRC-4 if required.
2 - Your network’s gateway address.
3 - The network’s subnet mask.
4 - The IP address of the email server that supports the address to which the

WRC-4 sends email alerts.
5 - The SMTP port used by your email server (usually 25).
6 - Up to four email addresses to which you want to send alarms.

The WRC-4’s RJ-45 (iNet) is normally attached to a DSL/Cable router, Ethernet hub
or switch. The supplied “Device Installer” software should be used to configure the
IP address of your WRC-4. The “Device Installer” software is also available on our
web site, www

.broadcasttools.com, under WRC-4 or under downloads.

1 - Install the “Device Installer” software on the PC used for the WRC-4 setup.
2 - Connect the supplied straight-through CAT 5 cable to the RJ-45 connector on

the WRC-4 labeled iNet and the other end to your hub or switch. NOTE: If
you are attaching the WRC-4 directly to your computer, you MUST use a
XOVER CAT 5 cable.

3 - Connect the supplied 9 VDC power supply to the WRC-4’s power jack. Verify

that the power LED and left “LINK” LED above the RJ-45 is lit.

4 - Start the “Device Installer” software.

a - Click on “SEARCH”
b - When the WRC-4 is found, click on the listed device. If more than one
WRC-4 is found, refer to the MAC address label attached to the WRC-4 RJ­45 case and click on the desired WRC-4, which should be highlighted.
c - Click on the “ASSIGN IP” button, then follow the instructions for setting a
static IP address, along with the subnet and gateway, if applicable.
d - After the WRC-4 has rebooted, click the “SEARCH” button, the configured
WRC-4 should be listed.
NOTE: You may have to click the search button more than once after
the reboot.

5 - If you are behind a firewall or router, you will need to port forward not only

port 80, but also ports 3001 and 3002 and set the SUN Java to direct.
NOTE: To set up port forwarding, refer to the manual supplied with the fire­wall or router.

CAUTION!

Installation of the
WRC-4 in high RF
environments should be
performed with care.
Shielded cable is sug­gested for all control
connections. All
shields should be tied
to the “CHASSIS
GROUND” terminal.
The station ground
should be connected to
the chassis ground
screw located behind
J4 as viewed from the
rear. For lightning
protection devices,
check out

www.polyphaser.com

and www.itwlinx.com.

Assigning an IP address
already in use by another
device may cause prob­lems with your network!

NOTE:

DHCP and Auto IP are
enabled with the IP
Address set at 0.0.0.0
by default. If you are
not familiar with
Ethernet enabled
equipment, it may be
useful to contact your
IT department or net­work administrator.

INSTALLATION

Alert Setup Dialog

The Alert Setup dialog specifies which alerts will be issued and the conditions that cause alerts.
Alerts are sent to all registered SNMP trap recipients and all registered e-mail alert recipients.

Low Threshold Sets the low analog threshold. If an analog value falls below this

value, an alert will be issued. NOTE: This value represents the
actual analog register value 0-1023, not the scaled value.

High Threshold Sets the high analog threshold. If an analog value exceeds this

value an alert will be issued. NOTE: This value represents the

actual analog register value 0-1023, not the scaled value.
Active (Analog) Activates/Deactivates the alert.
Active (Digital) Activates/Deactivates the alert. Alerts are issued when the state of

a digital input changes.
Com Fail Threshold Sets the communication failure threshold. The firmware keeps

track of communication failures between the on-board Web Server

and microcontroller. If the number of sequential errors reaches the

threshold, an alert is issued.
Active (Com Fail) Activates/Deactivates the alert.
Login Fail Threshold Sets the login failure threshold. This feature is turned OFF. The

default is set to 0. The firmware keeps track of failed login

attempts. If the number of sequential failures reaches the thresh-

old, logins are suspended and an alert is issued. This condition

may represent an attempt to breach the security of the system.

Logins are re-enabled by restarting the firmware, either through a

power-cycle reboot, or by rebooting via the Telnet setup menu at

TCP port 9999.
OK Save the settings and exit.
Cancel Exit without saving settings.

E-Mail Setup Dialog

The E-mail Setup dialog specifies settings
necessary to send e-mail alerts from the
WRC-4 using the SMTP protocol.

The email setup information needed below
is best obtained from the IT department, but
if that's not possible, try this. Open an
email message and select View, then
options on the selected email. The Internet
header information is displayed, which
shows all the information about the local
mail server. Remember that with the cur-

rent WRC-4, the mail server acts as a client.
This means there has to be either a valid account that the email is validated against or email forwarding is left
enabled. In most mail servers this feature is disabled to prevent being misused as a Spam server.

SMTP Server Address IP address of the e-mail server.
SMPT Port TCP port on the e-mail server (usually 25).
Return Address Return e-mail address for alerts sent from the WRC-4

(Don't forget to put the (less then, greater then) "<" and ">" characters around the address).
Host ID For most e-mail servers, this can be any string.
Recipient Addresses E-mail addresses (four) of alert recipients

(Don't forget to put the (less then, greater then) "<" and ">" characters around each address).
Save/Test Saves the settings and sends test e-mails to each recipient.
OK Saves the settings and exits.
Cancel Exits without saving settings.

WRC-4 Web Based Remote Control

INTERFACING

INTERFACING

A few precautions should be observed when interfacing to the WRC-4.

Analog input setup & connection

Each analog input may be configured an input range of 0 to 5 VDC or 0 to 10 VDC.
Exceeding these limits may damage the WRC-4.
Determine each input,s voltage range and set DIP SW3 according to the chart below:

Each analog input is unbalanced. Connect the high side of the analog source to the
desired input terminal labeled AN1, AN2, AN3 or AN4 and the groundside to the ter­minal labeled “GND”. Tie the shields to the “CHS” terminal.

Status input setup and connection

The status inputs may be configured to accept closures to ground or a voltage from
5 to 24 VDC. Exceeding these values may damage the unit. The WRC-4 is shipped
with the status inputs configured for closures to ground (JP5 = LOC). To configure
for an external voltage, simply move jumper JP5 to the “EXT” position and supply
any voltage from 5 to 24 VDC to the terminal labeled “EXT+V”. The status inputs
are labeled ST-1, ST-2, ST-3 and ST-4. The front panel LED’s are illuminated when
a status input is active.

Relay setup and connection

Each normally open dry contact relay is rated to 24 VDC at 1 amp. Exceeding these
limits may damage the unit. When selected, each relay momentarily closes for 1­second. This may be changed to a latching operation by turning SW2-1 OFF. The
normally open relays may be connected to terminals labeled K1 K1, K2 K2, K3 K3
and K4 K4. The front panel LED’s are illuminated when a relay is energized.

Open collector setup and connection

Each open collector output is rated at 12 VDC at 100ma. Exceeding these limits
may damage the unit. When selected, each open collector momentarily activates for
1-second. This may be changed to a latching operation by turning SW2-2 OFF. The
open collector outputs may be tied to the terminals labeled OC1, OC2, OC3 and
OC4. Use the terminal labeled “GND” (located on the status terminal) for the
ground return. In some cases, a pull-up resistor may be needed. NOTE: The EMF
diodes are tied to the 12 VDC supply. The front panel LED’s are illuminated when
an open collector is on.

NOTE:

Some configuration
changes may require
removing the cover of
the WRC-4. To do so,
use an Allen driver to
remove the single top
cover screw and lift off
the cover. Configuration
jumpers and DIP
switches are plainly
labeled on the PCB.

Analog Input Range: 0 to + 5 VDC Range: 0 to + 10 VDC

Input 1 SW3-1 OFF SW3-1 ON
Input 2 SW3-2 OFF SW3-2 ON
Input 3 SW3-3 OFF SW3-3 ON
Input 4 SW3-4 OFF SW3-4 ON
