FULL INTEGRATION WITH EARLIER SYSTEM

In keeping with TX's commitment to its customers to provide fully integrated enhancement capability, the 640-L3 is totally compatible with our earlier 640-L2 systems.

Incorporation of basic 640-L2 architecture allows 640-L3 to work with all L2 monitoring and control boards. The 640-L3 unit contains a new single PC board that replaces three boards on the earlier L2 unit: the CPU, EPR, and CM. This permits space for two additional boards yielding greater monitoring and control capabilities. The full 640-L2 command set is preserved and can be used to control the 640-L5 there by making upgrades to the L3 quick and easy. The 640-L3 also fully supports previous format variations thereby eliminating the need for expensive and time consuming software upgrades by the user.
