Upgrade to an LCD Display on an Anilam Crusader M CNC

If the 9" monochrome Computron 115-255 CRT display in the Anilam CRUSADER SERIES M control of your Anilam CRUSADER SERIES M CNC Machine has failed, look no further. Simply replace it with our QES1508-140 8.4" LCD. This rugged open-frame LCD mounts onto the 9-inch CRT mounting holes (after CRT had been removed) and has the same video and power input connections as the original 9-inch Anilam Crusader M 115-255, making it an easy retrofit with no need for signal adapters of any sort. Why settle for a refurbished CRT display with a limited warranty? Featuring a 600:1 contrast ratio, 450 Cd/M2 brightness, and a 2-year factory warranty, the rugged QES1508-140 monochrome LCD is an excellent replacement monitor for the legacy Computron 115-255 based on Computron 115DMX Product.
