Section 2 Installation / Initial Turn-On
Ranger ™ Mobile Series
2.8 Motorized RF Switch Connections
IMPORTANT:
If no patch panel or motorized RF switch is to be installed in the transmitter RF
output line, or if the RF switch does not have status switches, then a jumper must
be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1
(ground).
NOTE:
Refer to the Ranger External I/O Connections schematic 843-5560-105 for the
following connections: (S1 = Antenna position / S2 = Test Load position)
Connect the RF_SW_SEL_OUT at J15-9 on the External I/O board to the select
input on the switch. This output is a TTL open collector, active low, momentary signal
meant to cause a switch to the opposite position. The RF switch should then latch in that
position until pulsed again.
Connect one side of S1A and S2A (interlock switches on the rf switch) to J18-9 and
the other side to J18-10 on the External I/O Board in the transmitter. See diagram
843-5560-105 and/or 843-5549-141 sheet 20, for RF Mute interlock connections. This
is one of the transmitter rf mute interlock inputs and will mute the transmitter while the
switch changes position. Another jumper must be connected between J18-11 & J18-12
to operate the transmitter.
If the patch panel has status switches then connect S1B and S2B to the RF switch
status inputs on J14 of the External I/O Board in the transmitter. This allows the
GUI to display the position of the patch panel and will cause a transmitter mute if
neither of these connections are pulled low. These connections include:
• S1B and S2B commons connect to J14-1 (ground)
• S1B (antenna position) connects to J14-3
• S2B (test load position) connects to J14-4
NOTE:
If the patch panel does not have status switches then a jumper must be placed
between J14-1 (ground) and J14-3 (RF_SW_A_STAT) on the External I/O board.
The transmitter will be muted without this connection.
Connect Jumpers to the External I/O board for all unused External Interlocks. See
"2.6.1 External Interlocks" on page 2-6 for information on connections. If no external
interlocks are used, connect J18-1 to J18-8.
