VX SERIES
SWITCHING SYSTEMS
FOR AUTOMATIC TEST, INSTRUMENTATION AND COMMUNICATIONS
VX/256 MAINFRAMES
The Mainframes are 19" rack mounting units 5.25" high and 12"
deep with power supplies and motherboards to accept up to 16
VX Switch Modules, Display Modules and a Control Module.
These modules plug into the mainframes so that signal inputs
are accessible on the back panel and the LED displays are
visible through the translucent front panel.
The Mainframes accept any of the VX Switch Modules.
The VX Series of low-cost, versatile Switching Systems use a modular concept of Switch Modules,
Display Modules and Control Modules which can be assembled into VX/256 Mainframes as Matrices,
Multiplexers or Individual Relays.
All units have front panel LED displays and Status feedback of selected relays.
Control Modules are available for IEEE488 Bus, RS232 Serial, 10Base-T Ethernet LAN, and optional
Front Panel Manual Controls.
VX/256-E EXPANSION CHASSIS
These units have the same prewired motherboards as the main-
frames but do not have power supplies or control modules. They
are powered and controlled from the MESA Control Unit as de-
tailed in the MESA Bulletin.
VX/256-W WIRED UNITS
All mainframes and expansion chassis can be supplied in 16"
deep chassis with modules wired out to user specified connec-
tors in any required configuration.
SWITCH MODULES
Each Switch Module has sixteen relays and each relay can be
individually latched or unlatched and the Status displayed by
the CL16 Display Module.
The following Switch Modules are available:
VX/4(1X4) MODULE
This versatile module has four 1x4 two pole matrices which can
be configured as two 1x8 Matrices or one 1x16 module.
These modules have 16 relays with inputs on header connec-
tors and outputs bussed on the motherboard.
VX16/G2 has 16 two pole relays.
VX16/G3 has 16 three pole relays.
VX16/GC has 16 single pole Form C relays.
VX/G MODULES
VX/K MODULES
These modules have 16 individual relays and are not bussed to
the motherboard.
VX/KA has 16 single pole Form A relays.
VX/KC has 16 single pole Form C relays.
VXC MODULES
These modules are high frequency coaxial matrices with SMA
connectors.
VXC/4x4 has 16 single pole coaxial relays arranged in a 4x4
configuration.
VXC/8x2 has 16 single pole coaxial relays arranged in an 8x2
configuration.
CL16 DISPLAY MODULES
One Display Module is required for each Switch Module. It has
the controls for selecting and Latching or Unlatching the 16 re-
lays in the Switch Module. Sixteen LEDs in series with the
relays give an absolute indication that the relays are energized.
The LEDs are visible through the front panel and are a valuable
aid in checking the matrix status.
The CL16 also includes Status Feedback to the computer to
verify that selected relays are energized by checking the relay
drive output.
