Allow Blind Control
Blind Control is the ability to control a unit without a
connection. Active Front Panels and RollCall PC
programs use a RollCall connection to control a
module. RollTrack (used for setting, for example,
audio delay times to track video delays) does not
use a connection, but just sets the delay.
If the Gateway will be controlled by Blind Control
then Allow Blind Control must be enabled.
If Blind Control is not used then Allow Blind Control
may be disabled, giving protection against
incorrectly set-up RollTrack sources. Note, if
upgrading the gateway software, you must enable
Blind Control.
Where Am I?
This allows the 1U enclosure to be physically
located in a large system.
When this function is selected the TX and RX
LED's on the gateway card will flash.
Serial Speed
This group allows the serial port sped to be
selected.
115200 bps
57600 bps
38400 bps
19200 bps
9600 bps
4800 bps
2400 bps
Serial Speed
The baud rate is set between 2400 and 115200
baud.
The default speed for all RollCall serial connections
is 38,400 bps.
NB The RollCall PC software only supports speeds
up to 57600 baud.
Serial Mode
This item shows the current operating mode of the
serial port (RS422, RS232 or RS485).

Pass I_AM (Serial)
This controls whether the Gateway passes wide
area I_AM packets from the serial port to the
RollCall Network.
Normally this is enabled to allow PCs attached to
the serial port to be located by other units, but it
may be disabled if you wish to control the flow of
I_AM packets through a system.
NB Pass I_AM (Bridge) overrides both Pass I_AM
(Serial) and Pass I_AM (IP). So if Pass I_AM
(Bridge) is set I AM messages will be passed over
the bridge, irrespective of how the other controls
are set.
Pass TIME (Serial)
This controls whether the Gateway passes wide
area TIME packets from the serial port to the
RollCall Network. Normally this is enabled to allow
PCs attached to the serial port to be time servers,
but it may be disabled if you wish to control the flow
of TIME packets through a system.
NB The Gateway will always use the received time
stamp, whether it passes it on or not (but see also
Time from Logger).
Restart Unit
Selecting this function will re-boot the Gateway
system with any changes incorporated. This will
terminate any connections to the Gateway and to
modules in the 1U frame. This provides an easier
alternative to a power-down power-up operation.
Format Menu Cache
This deletes the existing module menu caches. The
caches will be recreated when the next menu client
connects.
Enable menu Cache
When selected the Gateway will cache module
menus sets. Clearing this checkbox will disable
caching and increase the menu upload times
