Fig. 4-7: The scheme of multi-module synchronization of three L-502 version 3 (top view of the
computer's motherboard)
The synchronization cable for a pair of L-502 modules, which, if necessary, must be ordered
separately, is designed to connect two L-502 modules. For connecting N pcs. of L-502 modules on one
motherboard you will need (N-1) pcs. of synchronization cables.
If, at least, one L-502 in this connection scheme does not have galvanic isolation, then the entire
system of these modules loses the galvanic isolation of the signal circuits from the ground and the
computer case.
The four-wire synchronization cable L-502-SYNC connects one pair of L-502 modules. The
pinout of the cable is made according to the "one-to-one" scheme. For orientation during
installation, use the key
the cable, when installed according to the scheme
direction.
