5.8 Custom Cable Splitter (“Y” cable):
This is a custom cable (often referred to as a Y-cable or a T-cable) that is used in applications
where it is necessary to access the DB-37 connector of a DVC “DigitEyes” camera (DVC-0A,
DVC-08 or DVC-10) camera at two separate interfaces.

"Y" Cable: Pinout of ca
mera side DB-37 connector (marked "C")
The splitter connects to the female DB-37 connector (see Table 1, above) of the camera via a
male DB-37 connector from which TWO branches emerge.
(1) The Mode Control branch: consisting of the Mode Control signals, which, in the case of MC1
and MC0 may be used as the gain and offset control voltages if the ext. gain/offset option is
installed.
