NEC NEAX2400IMX system manual LV0

OVERVIEW

Add-On Module

To designate the meaning of the upper 24 keys on an Add-On Module, FKYs 17 through 40 of the Dterm that works in combination with the DSS are used. The remaining 36 keys on the Add-On Module are assigned using FKYs 5 through 40 of the original port of the Add-On Module. The relationship between KYN, which appears in the AKYD command, and 60 keys on an Add-On Module is illustrated below. In Figure 1-9, an Add-On Mod- ule is connected to LV 1 as an example.

•The upper 30 DSS keys are assigned as the first port (even-numbered LV), in this example LV0.

•The remaining lower 30 DSS keys are assigned as the second port (odd-numbered LV), in this case LV1

•The Add-On Module is physically connected to the odd-numbered LV.
