DK14 InstallationDK8/DK14 Compatibility
Generally, Strata DK components are upward compatible to make upgrading cost-effective. 
Furthermore, there is a lot of cross-compatibility between similar systems. Most of the PCBs that 
were introduced for the DK14 can also be used in the DK8 system (see Table 1-2). Also, a number 
of DK8 PCBs can be used in the DK14 (see Table 1-3).
