Revision 1.2 7702/3BPX-IF-1
1. OVERVIEW
The 7702BPX-IF and 7703BPX-IF modules are wide band 2 x 1 RF protection switches that provide auto-
changeover capability by detecting a change in the input power level. Manual control or automation
control via the GPI port is also provided. This is a latching switch which maintains switch state on loss of
power. It is designed for intermediate frequency satellite earth station links or CATV signals and operates
over a wide frequency range of 10MHz to 850MHz.
The 7703BPX-IF model has integrated VistaLINK®technology for remote control and monitoring capability
via SNMP. This provides the user with the ability to locally or remotely configure and monitor parameters
such as module status, selected input, power level and switching threshold.
In the auto-changeover application, both products can be configured to have a Main input and a Standby
input. In this configuration, it will automatically switch to the Standby input when the Main input power is
weak or lost. Switch-back to the Main input when the signal is re-established may be configured to occur
automatically or manually. The 7702/7702BPX-IF may also be configured to operate manually as a 2:1
switch, which may be controlled locally or remotely via GPI or SNMP (7703 model only).
The 7702BPX-IF and 7703BPX-IF occupy one card slot and can be housed in a 1RU frame that will hold
up to 3 modules, a 3RU frame that will hold up to 15 modules, a 350FR portable frame that will hold up to
7 modules or a standalone enclosure which holds 1 module.
Features:
Wide operating frequency range, 10MHz to 850MHz
Intelligent auto switching with input power detection
User-definable threshold levels on 7703BPX-IF version
Maintains switch state and RF channel on loss of power to card or frame
Supports automatic or manual control via GPI or SNMP on 7703BPX-IF
Switch state indication via GPO
Card edge LEDs indicate active input channels, output channel and power levels below threshold
Fully hot-swappable from front of frame
Comprehensive signal and card status monitoring via four digit card edge display or remotely
through SNMP and VistaLINK®on 7703 version
VistaLINK®capability is available when 7703BPX-IF modules are used with the 3RU 7800FR or
350FR portable frame and a 7700FC VistaLINK®Frame Controller module in slot 1 of the frame

Figure 1-3: Typical Application of Protection Switch in IF Uplink Transport System
Figure 1-3 illustrates the use of the BPX-IF as a protection switch in an earth station IF satellite uplink
transport system. The modulated video signal at 70 / 140MHz intermediate frequency is fed into the
Evertz Microsystems 7702/3DA4-RF 1x4 active splitter for distribution to multiple transmit paths. Two
signals from different sources are directed to the 7702/3BPX-IF, one acting as a primary source and the
other as a backup signal if the primary fails. The IF signal is then transported over optical fiber up to 60km
using the optical transmitter / receiver pair, 7707IFTA and 7707IFRA from Evertz Microsystems from the
NOC ( Network Operations Centre ) to the dish. The protection switch can also be used to provide
redundancy to the fiber optic link as shown in the above diagram. This protects against a fiber break or
optical transmitter / receiver failure. The switch is a latching switch, maintaining the switch state on loss of
power.

6.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J9 located at the front of the module determines whether local faults (as
shown by the Local Fault indicator) will be connected to the 7700FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this jumper in
the On position. (Default)
When this jumper is installed in the Off position local faults on this module will not be
monitored.
6.2. MONITORING AND CONTROL OF 7703BPX-IF CARDS THROUGH SNMP
OR CARD EDGE MENU SYSTEM
The card does not require any reconfiguration or adjustment to monitor and control through SNMP or the
card edge menu system. Updates to configuration and status are visible in both systems.
6.3. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES (7703BPX-IF ONLY)
UPGRADE: The UPGRADE jumper J12 is used when firmware upgrades are being done to the module.
For normal operation it should be installed in the RUN position. See the Upgrading
Firmware chapter in the front of the manual binder for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the UPGRADE
jumper into the UPGRADE position. Install the Upgrade cable provided (located in the vinyl
pouch in the front of this manual) onto the SERIAL header J14 at the card edge. Re-install
the module into the frame. Run the upgrade as described in the Upgrading Firmware
chapter of this manual. Once the upgrade is completed, remove the module from the
frame, move the UPGRADE jumper into the RUN position, remove the upgrade cable and
re-install the module. The module is now ready for normal operation.
6.4. SELECTING THE GPI PULL-UP VOLTAGE
The GPI jumpers J4 and J5, located at the rear of the module, selects whether the general purpose inputs
GPI1 and GPI2 will be pulled up to +5 volts or +12 Volts. Figure 2-2 shows the jumper configuration and
the GPI input schematic. Jumper J5 is used for GPI1 and J4 is used for GPI2.
GPI: To set the pull-up voltage to +5 volts set the jumper to the LO position,
To set the pull-up voltage to +12 volts set the jumper to the HI position,
6.5. USING THE GPO OUTPUTS
There are three pins on the 6 pin terminal strip dedicated to the GPO, NC (Normally Closed), NO
(Normally Open) and Common, connected as shown in the circuit diagram of section 2.1. The common
connection will switch between NC and NO on a change in state of the RF switch. This GPO is intended
to indicate a change in state of the switch. The signals on NC and NO are to be provided by the user.

7. VistaLINK®REMOTE MONITORING/CONTROL (7703BPX-IF ONLY)
7.1. What is VistaLINK®?
VistaLINK®is Evertz’s remote monitoring and configuration platform which operates over an Ethernet
network using Simple Network Management Protocol (SNMP). SNMP is a standard computer network
protocol that enables different devices sharing the same network to communicate with each other.
VistaLINK®provides centralized alarm management, which monitors, reports, and logs all incoming alarm
events and dispatches alerts to all the VLPro Clients connected to the server. Card configuration through
VistaLINK®PRO can be performed on an individual or multi-card basis using simple copy and paste
routines, which reduces the time to configure each module separately. Finally, VistaLINK®enables the
user to configure devices in the network from a central station and receive feedback that the configuration
has been carried out.
There are 3 components of SNMP:
1. An SNMP manager also known as a Network Management System (NMS) is a computer running
special software that communicates with the devices in the network. Evertz VistaLINK®Pro Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK®enabled fiber optic products.
2. Managed devices (such as 7703BPX-IF cards), each with a unique address (OID), communicate with
the NMS through an SNMP Agent. Evertz VistaLINK®enabled 7700 series modules reside in the 3RU
7700FR-C MultiFrame and communicate with the manager via the 7700FC VistaLINK®frame controller
module, which serves as the Agent.
3. A virtual database known as the Management Information Base (MIB) lists all the variables being
monitored, which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK®network, see the 7700FC Frame
Controller chapter.
