GX SERIES CHASSISGX SERIES CHASSIS

GX SERIES CHASSIS

The GX Series Chassis are built as either single chassis Mainframes or as Expansion Chassis con-

trolled by one GX Series Control Unit. For larger systems having more than 16 groups, the MESA Con-

trol Unit is used to control several GX/16 Control Units.

These single chassis Mainframes are built with their own

dedicated power supplies, a Control Module, and have

front panel status LEDs. Available Mainframes include

the GX/8 controlling 8 groups of signals or the GX/16

controlling 16 groups of signals. The number of Groups

being switched by a Mainframe is limited to 16.

GX/8 MAINFRAMEGX/8 MAINFRAME

GX/8 MAINFRAME

This Mainframe switches up to 8 groups of signals in a 4x2 or

8x1 configuration. Each group is typically made up of one or

two Switch Modules.

Example: Using VX16/G2 Switch Modules with 32 wires per

module, each switched group can handle up to 64 wires.

GX/16 MAINFRAMEGX/16 MAINFRAME

GX/16 MAINFRAME

This Mainframe switches up to 16 groups of signals in a 4x4,

8x2 or 16x1 configuration. Each group typically has one switch

module.

Example: Using VX16/G2 Switch Modules with 32 wires per

module, each group can have up to 32 wires.

GX CONTROL UNITSGX CONTROL UNITS

GX CONTROL UNITS

One Control Unit drives several Expansion Chassis and

is used for configurations requiring more than 16 switch

modules. Control Units include a Control Module and

the power supplies that are needed to energize a large

number of Switch Modules. The following Control Units

are available:

GX/8 CONTROL UNITGX/8 CONTROL UNIT

GX/8 CONTROL UNIT

GX/16 CONTROL UNITGX/16 CONTROL UNIT

GX/16 CONTROL UNIT

This Unit controls up to 8 Groups. Each Group is typically

made up of one or two switch modules and handles a large

number of signals.

This Unit will control up to 16 Groups, with each Group switch-

ing a large number of signals.

MESA CONTROL UNITMESA CONTROL UNIT

MESA CONTROL UNIT

When more than 16 signal Groups are required, control is

achieved by using a MESA Control Unit, detailed in the MESA

Bulletin, that drives up to 16 of the GX/16-E Expansion Chas-

sis via GX/16 Control Units.

ANSION UNITSANSION UNITS

ANSION UNITS

These Units are designed for large Group Switches re-

quiring more Switch Modules than can be assembled in

one mainframe.

Up to 16 modules can be assembled in each chassis and up

to 16 chassis can be controlled from the GX Control Unit,

which also supplies power and controls via chassis intercon-

nect cables.

Example: Using VX16/G3 Switch Modules with 48 wires

per module and two GX/8-E Expansion Chassis, each group

can switch 96 wires in a 16x1 multiplexer.

ERIESERIES

ERIES are single ended, high frequency coaxial mod-

ules built as either 4x1 or 8x1 configurations. Different CX

modules have different bandpass specifications and they are

built with either with Type A or Type S relays as shown in the

CX Bulletin.

Example: Switching 8 groups with 8 coaxial signals per group

and needing a bandpass of 1 GHz would require eight CXR/

8x1-G Modules.

LX LX

SERIESSERIES

SERIES are general purpose, low to medium frequency

modules. One LX8/G2 Module can switch a group of 8 pairs,

or 16 single wires, as shown in Fig.1 of the LX Bulletin. The

modules are built with Type S, Type M or Type LT relays.

Example: Switching 16 groups with each group consisting of

four wire pairs would require eight LX8/G2 Modules.

VXVX

SERIES SERIES

SERIES are low to medium frequency switch modules.

The VX16/G2 Module can switch 16 pairs, or 32 individual

wires, and the VX16/G3 can switch up to 48 wires as shown

in the VX Bulletin. The modules are built with Type S, Type

M or Type LT relays.

Example: Switching 16 groups of 48 wires each would re-

quire sixteen VX16/G3 Modules.
