SLOT6
LNB1 supplied to pin 1 (LNB
feed) of SLOT2
J30
Used to specially configure the serial
digital module in SLOT 3 (refer to HRS-
HB-6 SUPPORT MODULE HANDBOOK

cable.
J31
Used to specially configure the serial
digital module in SLOT 6 (refer to HRS-
HB-6 SUPPORT MODULE HANDBOOK
Section 3.4).

connected to special interface
cable.
J2
Connects the output of LNB1 (SLOT7) to
the external voltage feed (J5 & J26). J2
is highlighted in
red
.
J2 is the 4 pin connector next to J8
LNB1 connected to J5 & J26
These jumpers are electrically in
parallel, both should be fitted.
J3
Connects the output of LNB2 (SLOT8) to
the external voltage feed (J5 & J26). J3
is highlighted in
red
.
LNB2 connected to J5 & J26
These jumpers are electrically in
parallel, both should be fitted.
SW1
‘EMPTY ’position masks the alarms from
unused
modules. ‘USED’ should be set if
the slot is occupied.
