1. INTRODUCTION
The Dual Switch Controller monitors the position and provides control for two Dielectric
switches with either waveguide or coaxial configuration. The controller provides multiple
ways in which to manage switches, including remote control for integration with other
systems. The unit also allows customization for transmitter interlock delay to ensure
that connected transmitters are powered down before switching.
The Dual Switch Controller provides a high degree of flexibility to users. The unit’s
status is available to local operators via the front panel touch-screen interface.
Additionally, the data are available to remote terminals via a web interface or SNMP.
There are also connections available for remote control and monitoring via direct contact
connections.
2. SETUP
The Dual Switch Controller is configured at the factory with default values for the
transmitter interlock delay and interface settings. In some instances, the pre-configured
values may suit the system it is going into; however, it is necessary for the installer to
ensure that all pertinent configuration values are set properly after the system is
installed (e.g. switch movement delay).
When the Dual Switch Controller is first powered on, or after the rear-panel Master INIT
button is pressed, the unit is set to DHCP operation and queries the network for an IP
address. If DHCP is not available on the network, the unit sets itself to the default IP
address 192.168.0.100. A static IP address must be configured by the user before the
network is used for web access, SNMP, or Plus-X communications. The simplest method
for setting the static IP address is via the front panel touch screen. By selecting CONFIG
-> Network the IP address of the Dual Switch Controller can be set as shown in Figure 1
and Figure 2 below. If front panel access is not possible, the Web interface can be
accessed by typing the Hostname DUALRFSWITCH/ into the address field on a web
browser.

Figure 2: IP Address Configuration
The Control Voltage, either 12 or 24 VDC, can be selected via a touch screen adjustment
as shown in Figure 3. The default choice is 12 VDC. Changing this choice only changes
the voltage used for switch movement commands. Connections marked as “V+” will
always supply 24VDC to supply enough voltage to command the inputs.

Figure 3: Voltage configuration
Switch 1 and Switch 2 can be configured to enable the switch and the load interlock
mode. In addition, the interlock delay can be set to define how long to wait after
opening the interlock before starting switch movement as shown in Figure 4. When the
Dual Switch Controller receives the command to move a switch under its control it will
open the normally closed interlock and then wait the preset delay before giving the
command to move. Operators should test that this time limit is enough before operating
the switch to prevent the switch from moving while under RF power. This time is user
selectable from the touchscreen or web interface. The minimum value is 2 seconds.
However, the user can increase this time as desired. The current value for the delay can
also be retrieved using SNMP.

3. INSTALLATION
The Dual Switch Controller is a rack mounted module built as a 3.5” (2U) enclosure to fit
a standard 19” rack. This unit houses the control processor and all the interconnections.
The front of the unit allows an operator interface via touchscreen while the rear panel
allows access to the remote connection points.
The front panel of the Dual Switch Controller is shown in Figure 5. The LED indicator will
show green if the power is on. This same LED will turn red to indicate an alarm condition
when a switch is in a failed state or when the load interlock is open.
Figure 5: Front panel for Dual Switch Controller
The rear panel of the Dual Switch Controller is shown in Figure 6. Note that default
assignments to the output port labels, Tx A and Tx B, and the input port label, Load, are
used as the nomenclature on the rear panel. Table 1 provides a short functional
description of each feature on the rear panel of the Dual Switch Controller.

The pinouts of the rear panel for the Dual Switch Controller are shown in Figure 7. The
configuration uses external pushbuttons and LEDs with dropping resistors for remote
control and indication respectively (TB2, TB5 and TB6). Figure 7 assumes normally

closed (NC) interlock contacts for all transmitters and uses the default labels for each of
the ports on the RF Switches.

Note: connections labeled V+ on the rear panel terminal blocks shall always be held at
+24VDC independent of user selected RF Switch Control Voltage.
The Dual Switch Controller is designed for use with one or two 4-Port RF Switches of
either waveguide or coaxial configuration. Factory default settings assign the following
labels to each of the four ports of the two switches that may be simultaneously
controlled by the Dual Switch Controller (see Figure 8):
Input Port 1 = Tx A

Input Port 2 = Tx B
Output Port 1 = Ant
Output Port 2 = Load
Note: Unless otherwise stated, the rest of this document will assume the default labels
are applied to each port of the RF Switch.
The operator can adjust the labels for each switch from the web interface.
The prescribed pinouts for the rear panel RF Switch Connectors (Switch 1 and Switch 2)
are provided in Table 2. There are two versions of the waveguide switch before the
60000 series, one with a numerical pin-out and one with an alphabetic pin-out. Please
contact the Dielectric factory for questions on these older units.
