SWITCH MATRIX UNITS
MAINFRAMES
PX-1
PX/512 SWITCH MATRIX
The PX/512 Series of Switching Matrices are compact and economically priced units using high
reliability Reed Relay Modules assembled into pre-wired Mainframes or Expansion Chassis to
assemble a 32x16 Matrix, two 32x8 Matrices or a 64x8 Matrix with either single or two pole signal
switching. Computer Control can be from IEEE488 BUS, RS232 Serial or 10Base-T LAN.
SPECIAL FEATURES:
• Matrix layout for high bandpass of 20 MHz and crosstalk
less than -40 dB at 10 MHz.
• Status Feedback to the computer from the relay coil drive
gives positive assurance that selected relay is energized.
• Interrogation Mode gives readout of all switched paths in
terms of inputs and outputs connected.
The units are all 19" rack mounted Chassis, 3.5" high, pre-wired to accept up to 16 of the PX/32 Switch
Modules and a Control Module. Signal inputs and outputs are available with either coaxial BNC recep-
tacles (-N), Header type connectors (-H) or screw terminals (-S).
These are stand alone pre-wired chassis with low noise
power supplies and motherboards to accept 16 Switch Mod-
ules and a Control Module.
There are two basic series of Mainframes:
PX/512-1 MAINFRAMES
These are 16" deep chassis pre-wired for single pole switch-
ing matrices.
PX/512-1A has a pre-wired motherboard accepting 16 of the
PX/2x16-1 Switch Modules in a 32x16 Switch matrix configura-
tion.
PX/512-1B has a pre-wired motherboard accepting 16 of the
PX/2(2x8)-1 Switch Modules in two separate 32x8 matrices
which can be combined as one 64x8 matrix.
PX/512-2 MAINFRAMES
These are 21" deep chassis pre-wired for two pole switching
matrices.
PX/512-2A has pre-wired motherboards accepting 16 of the PX/
2x16-2 Switch Modules in a 32x16 matrix configuration.
PX/512-2B has pre-wired motherboards accepting 16 of the PX/
2(2x8)-2 Switch Modules in two separate 32x8 matrices which
can be combined as one 64x8 matrix.
EXPANSION CHASSIS
These units are pre-wired to accept 16 Switch Modules
and an Expansion Interface Module so that several chas-
sis can be controlled and receive power from one MESA
Control Unit as shown in the MESA Bulletin.
These Expansion Chassis are available in the same matrix
configurations as the Mainframes.
PX/512-E-1 EXPANSION CHASSIS
These are 16" deep chassis accepting single pole switch mod-
ules.
PX/512-E-1A has a 32x16 matrix configuration.
PX/512-E-1B has two 32x8 matrices which can be combined
as one 64x8 matrix.
PX/512-E-2 EXPANSION CHASSIS
These are 21" deep chassis accepting two pole switch mod-
ules.
PX/512-E-2A has a 32x16 matrix configuration.
PX/512-E-2B has two 32x8 matrices which can be combined
as one 64x8 matrix.
CUSTOM CHASSIS
The Mainframes and Expansion Chassis can be supplied wired
out to customer specified connectors or in special configura-
tions.
• Optional Manual Control with visual display of selected switch path.
• Optional nonvolatile Ram for storage of preset or power-up configuration.
• VMCS Virtual Manual Control Software for Remote operation using a full
Graphical User Interface.
