of two ways:
a) Connecting the P910 or P911 to Encoder SK1.
b) Connecting an alternative cable to the Krone connections on Encoder SK2.
27. Note that Encoder SK1 and SK2 are connected in parallel; only one socket can be
utilised.
28. Pin out details of Encoder sockets SK1 and SK2 are shown in Table 1.
