The MESA Series Controllers make it possible to control several different CYTEC Expansion Chassis via a single control module. They are used to build large matrix or multiplexer configurations or simply run different types of expansion chassis. The MESA also reduces the costs of large systems since each chassis does not need it’s own control module, and often they do not need power supplies either. Expansion Chassis can be any combination of different series types from Cytec’s complete line of switching products.
The MESA II holds the overall system’s single Control Module, and it directly controls multiple expansion chassis. The MESA II can be used to build large Matrix or Multiplexer configurations requiring multiple expansion chassis, or it can simply run several different expansion chassis. The MESA II Switching System is composed of one primary MESA II Control Module and up to 16 expansion chassis. It is possible to add an optional redundant/backup control . Expansion Chassis are typically high density solid state switches, such as the DX/256×256, TX/128×128, DX/64×64 or VDX/32×32. However, the Expansion Chassis can be many combinations of product types, including but not limited to CXAR, CX, LX, HXV, VX, and PX Matrices, JX Multiplexers, GX and RS Group Switches, VDX Video Switches, FX and FO Fiber Optic Switches, HDX 4600 High Density Matrices and DX Digital Matrices. Full details on each expansion chassis type are given in their respective bulletins, which can be viewed in the full product catalog or downloaded from www.cytec-ate.com. Standard computer control is via IEEE488, RS232 and Ethernet TCP/IP, and Keypad Manual Control can be supplied as an option.
Individual Expansion Chassis are normally supplied with 6 foot cables. The expansion chassis can be furnished with ribbon cables up to a length of 20 feet on request. Expansion chassis may be located up to 200 feet from the MESA if a better, shielded cable is used. To discuss these options please contact CYTEC’s sales staff.
The MESA II Control Unit is supplied with a +5VDC supply for logic in most Matrix or Multiplex operations. The relay drive voltage is provided in each powered expansion chassis. However, some applications require a larger number of switches to be closed. For these cases, Cytec offers an Auxiliary Power Supply Chassis. Redundant, hot swap DC power supplies are also offered for large systems or environments that need redundant protection. Contact Cytec for details on these options.
