SETTING CONSOLE IDs FOR 2015 PROCESSING CORES
Unlike Apollo, Artemis Shine and
Beam consoles using 8RU cores,
and Artemis Light and Summa
consoles using Pre-2015 cores,
where the Console IDs are set up in:-
/home/MasterControl/guardian/
console.config on both of the MCS
Control processors, Summa consoles
running on V3.0 software and above
using the newer 2015 Com-E based
processing cores use the two sets of
DIP switches on the JN6209 sync card
shown right to define the Console
Id’s first two octets of the IP address
range which is made up from the
Customer ID and the Core ID.
Note: the earlier JN6178 sync card
also has these switches and if V3.0 is
installed on a console with this sync
card it will also use its DIP switches to
define the customer ID.
JN6209 SYNC CARD AND ITS CONSOLE ID SETTING DIP SWITCHES
The DIP switches are arranged as per the
diagram on the right (same orientation
as the above pictures, with the BNC
connectors to the left).
The screen print on the PCB board
allocates 10 bits to the customer ID and
6 bits to the core ID. This is related to
a potential future development to allow
for a greater number of customer IDs.
This has not yet been implemented,
meaning both IDs remain 8 bit.
CustomerID
The customer ID is set by DIP switches
C0 to C7, where C0 is the least significant
bit (1) and C7 is the most significant bit
(128). A switch is set to on (1) when the
switch is down (ie: closest to the PCB)
and set to off (0) when the switch is up
(ie: away from the PCB).
Normally a console is allocated a
customer ID by Calrec, however Summa
is designed to be fully configurable by
the customer, so any value (with the
exception of the values listed below) can
be selected.
Logically, multiple consoles owned by the
same customer should have the same
customer ID, but again this is not vital.
CoreID
The core ID is set by DIP switches R0
to R5 and C8 to C9 (ie: C8 is equivalent
to R6; C9 is equivalent to R7), where
R0 is the least significant bit (1) and
C9 is the most significant bit (128). A
switch is set to on (1) when the switch
is down (ie: closest to the PCB) and
set to off (0) when the switch is up
(ie: away from the PCB).
Normally a console is allocated a core ID
by Calrec, however Summa is designed
to be configured by the customer, so any
value can be selected.
Logically, multiple consoles owned by the
same customer should each have a unique
core ID. This is vital if two consoles are to
be networked.
ExcludedcustomerIDs
Certain IP addresses are reserved
within the Linux environment and as
such cannot be used as a customer ID
(1st octet of the IP address).
If excluded customer ID’s are used, the
console will boot into an unusable state
where neither control processor becomes
active. In such an event, the only solution
is to: power down the processing core;
remove the sync card; modify the
customer ID to a legal value’ reinsert the
sync card; and repower the processing
core.
Excluded customer IDs are:
 0 – 3 Calrec reserved
 127 local host
 224 – 239 multi-cast
 240 – 255 Linux reserved
If the potential development to provide
10 bit customer IDs is implemented,
the following customer IDs will also be
excluded:
 256 – 259 Calrec reserved
 383 local host
 480 – 495 multi-cast
 496 – 511 Linux reserved
 512 – 515 Calrec reserved
 639 local host
 736 – 751 multi-cast
 752 – 767 Linux reserved
 768 – 771 Calrec reserved
 895 local host
 992 – 1007 multi-cast
 1008 – 1023 Linux reserved
Note: Core IDs are unaffected and can be
any value
