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.

2. INSTALLATION
The 7702BPX-IF and 7703BPX-IF both come with a companion rear plate that has three BNC (F type
optional) connectors and a six pin terminal strip. For information on mounting the rear plate and inserting
the module into the frame see section 3 of the 7700FR chapter.
Figure 2-1: 7702BPX-IF and 7703BPX-IF Rear Panels
INPUT A, B: The two BNC ( F type optional ) connectors are RF inputs that accept frequencies over the
range of 10MHz to 850MHz. The A connector is for the Main input and the B connector is
for the Standby input.
OUTPUT: This BNC ( F type optional ) connector is the output from the switch.

2.1. GPIO
A 6-pin removable terminal block labeled GPIO contains 2 GPI inputs and 2 GPI outputs
GPI: The two top pins on the 6 pin terminal strip are used for two General Purpose inputs (GPI). The
GPIs can be configured as active high or low by setting DIP switch 3. GPIs are active low
when Dip switch 3 is Off and GPIs are active high when Dip switch 3 is in On ( positioned
closest to the PCB ). The GPI inputs are opto isolated with an internal pullup resistor to +5V or
+12V as shown in Figure 2-2. See section 6.4 for information on selecting the pull-up voltage.
