RS Series Analog or Digital Communications Switching Systems with D Type Connectors

The RS Series of computer controlled switching systems are designed to switch multiwire groups of signals on standard D9, D15 or D25 connectors. These systems are typically used for signals such as parallel TTL, RS232, RS422, WAN or Modems, but they can also be used for any group of analog or digital signals having a bandpass below 30 MHz or data rate below 20 Mbps. A modular design concept is used that provides configuration flexibility by allowing different control modules, switch modules and display modules to be assembled in one chassis. LED displays and switch point Status Feedback are available on all systems. Computer control via 10/100 Ethernet LAN ( TCP ), IEEE488 (GPIB) and RS232 is standard, while USB, and manual controls are optionally available.

Optionally using a MESA Controller allows up to 16 Expansion Chassis to be controlled from a single IEEE488 address, RS232 port or LAN Interface. A Manual Control Option allows control of all Expansion Chassis through a front panel Keypad with LCD Display. The MESA allows cost effective building of large systems since Expansion Chassis do not require additional power supplies or Control Modules, and additional Expansion chassis can be added as your needs grow or change.

Control Options
  • Optional Manual Control: Options include keypad, pushbutton and pushwheel. See the page on Manual Control here.
  • Standard Remote Control: Connect your P.C. to the switch via GPIB/IEEE488, RS232/USB or LAN. 
  • Mesa II Expansion System: Use a Mesa II Controller to control up to 16 expansion chassis. See the page on Mesa Control here.

RS Series Multiplexer

RS/16-MF Rear Panel
RS/16-MF

The RS/16-MF is a passive, bidirectional relay-based Multiplexers, connecting one of up to 16 multiwire signal groups to a single signal common. 

  • Nine, fifteen or twenty-five wires are switched simultaneously. 
  • These pre-wired chassis hold RS Switch Modules built with D9, D15 or D25 style connectors and switch 9, 15 or 25 wires. 
  • The RS series are 19″ rack mounted units 3.5″ high and 15.6″ deep with power supplies, LED Displays and pre-wired motherboards which accept the RS Switch Modules. 

RS Series Switch Modules

RS Switch modules are available as 9, 15 or 25 wire versions with D9, D15 or D25 connectors. All wires are switched in unison using Type A armature relays suited for analog or digital data. The modules switch the signals through the system as a 1 to 1 connection and act exactly like a piece of cable. No impedance matching necessary

PLUG or SOCKET D TYPE CONNECTORS To specify Plug (male) D type connectors, add -P to the Switch Module part number. Adding -S specifies Socket (female) connectors. For example, the RS/15-S is built with a subminiature D15 Socket connector.

The following mating connectors can be purchased for a small additional charge.

  • D9-R – Nine pin ribbon cable connector
  • D9-C – Nine pin crimp type connector
  • D15-R – Fifteen pin ribbon cable connector
  • D15-C – Fifteen pin crimp type connector
  • D25-R – Twenty-five pin ribbon cable connector
  • D25-C – Twenty-five pin crimp type connector

SWITCH SPECIFICATIONS

Type A relays are sensitive, high reliability armature relays and are well suited for multiple wire data signals. They are rated for 10 million operations when used as specified.

RSM Series Matrices

The RSM Series are bidirectional, non blocking relay matrices. A modular design allows the configuration of matrices from 1×8 or 2×4 up to 16×8 or 32×4. Custom configurations are easily built to your specs.RSM Matrices are designed to switch multiwire data communications signals such as RS232, RS422 and RS530 Subsets. RSM Systems can switch nine, 15 or 25 wires and are available with D9, D15 or D25 style connectors. Mainframes are 19″ rack mounted chassis, 7″ (4U) high and 21″ deep, with power supplies and pre-wired motherboards that hold Switch Modules, LED Display Modules and Control Modules.

A complete 128 channel mainframe requires 16 display modules. NOTE: If you do not require all 128 channels then you can request fewer display modules which will reduce the price of the system.

Available Configurations
  • 16×8: These Mainframes hold up to 16 of the RSM/1×8 Switch Modules assembled in a 16×8 configuration. Bandpass is DC to 40 MHz (-3dB).
  • 32×4: These Mainframes are built with up to 16 of the RSM/2(1×4) Switch Modules assembled in a 32×4 configuration. Bandpass is DC to 30 MHz (-3dB).
  • 2(16×4): These Mainframes hold up to 16 of the RSM/2(1×4) Switch Modules assembled as a dual 16×4 configuration. Bandpass is DC to 40 MHz (-3dB).

RSM Switch Modules

The RSM Switch Modules are built as either a single 1×8 matrix, or as a dual 1×4 matrix configuration. They are bidirectional and switch 9, 15 or 25 wires to D9, D15 or D25 connectors. Switching is done with high reliability, passive Type A Relays.
