Verifying dome software and AHC firmware versions
In order to operate Legend IP domes with Tyco/AD (RS-422) keypads, your domes must be installed with
v2.1.9 (or later) software and the active housing cards (AHCs) in the domes must be installed with v7 (or later)
firmware.
To verify the software version of the domes and the firmware version of the installed AHCs:
1. Select System and Status in the menus of the graphical programming interface. Refer to the Legend IP
User Manual (1055713) for details about using the programming interface.
2. Scroll down to the Site info and AHC info sections.
Wiring Tyco/AD keypads to Legend IP domes
If your domes have the correct dome software and AHC firmware ( Verifying dome software and AHC
firmware versions ), then connect your Tyco/AD keypads to the data connections of the domes as shown in
Figure 44 and Table 12 .
Be aware that you lose streaming position reporting out of the AUX ports while you have Tyco/AD keypads
wired to Legend IP domes.
