WVRC-4 Installation and Operation Manual
OVERVIEW
Product Overview
The WVRC-4 provides a cost-effective, half-rack solution for web based and/or
recordable voice response dial-up transmitter site control. The WVRC-4 was
designed from a users point of view, so all of the basic functionality you need is
included to control your site equipment, while including the accessories other man-
ufacturers consider optional. Each analog (metering), status, silence sensor, temper-
ature sensor and power failure input can be configured to email up to four individ-
ual email addresses, allowing different input alarms to be routed to different email
recipients.
The WVRC-4 is equipped with a browser based 100-event program scheduler for
relay control and alarm muting, along with an FIFO 8192-event alarm logger. The
user can enable a sound effect to play when an out of tolerance alarm is generated.
We have also provided SNMP capabilities to allow multiple units to be monitored
with any SMNP manager software package.
The WVRC-4 is equipped with four high-resolution analog (metering) channels,
while each of the four optically isolated status channels may be configured for 5 to
24vdc wet or dry (contact closures) status monitoring. The four control channels are
equipped with independent SPDT one-amp relays for each raise/on and lower/off
function for a total of eight relays. These relays may be latched, unlatched (Web
mode only) or momentarily closed.
The WVRC-4 is supplied with spoken words and phrases in English, while the user
is free to record words and phrases in any language. In addition, the WVRC-4 may
be programmed for dial-up operation via HyperTerminal, while the Java applet pro-
gramming can be performed using your favorite web browser.
System expansion may be accomplished by cascading multiple WVRC-4’s on the
same telephone line and/or Ethernet switch.
