ARC130S 060801 Version 1 Issue 1
4.20
Update
This allows you to select whether a change in
output display parameters occurs at field or frame
rate. This is significant if line 23 signalling is used
(this signal is only present once per frame). If the
ARC130S is in the Auto mode and line 23
signalling is set to Auto output, when a change in
aspect ratio is signalled at the input, it is preferable
that the output video change and the output line
signalling occur together. This may not be the case
due to internal vertical genlock timing or timing of
the external reference. To ensure that the video
change and output signalling occur together it is
recommended that Update is set to “Field 1” when
in the Auto mode.
If “F1 & F2” is selected, the video at the output will
change at the first available field boundary after a
button has been pressed or a remote control
command has been received.
If “F1 only” or “F2 only” is selected the video at the
output will only change at the start of the
appropriate output field type after a button has
been pressed or a remote control command has
been received.
RC Add
When this item is selected the ARC displays the
RollCall address of the unit in Hexadecimal. Note
that the address cannot be changed using this
menu entry, it can only be changed using the rotary
switches as described in Section 3.
Log On
– selecting this menu item toggles
between Log On and Log Off. This item turns On
and Off the RollCall Log server function in RollCall
network applications.

RS422
This allows the RS422 communications function to
be set up.
Baud
controls the Baud rate used on the RS422
remote control channel.
The rate may be set to any of the following:
38400
9600
4800
Note that if the ARC is to be controlled by a Snell &
Wilcox ARC remote control unit then the Baud rate
must be set to 38400 Baud.
422 Bit
– this sets the number of data Bits used on
the RS-422 remote control link when the Normal
remote control protocol is in use (see below).
Note that if the ARC is to be controlled by a Snell
and Wilcox ARC remote control unit then this must
be set to 7 Bits
.
Proto
– this selects the remote control protocol in
use on the RS 422 remote control link.
Normal
is
the default protocol and this provides control of all
parameters of the ARC.
If
Alt
is selected an alternate protocol is active.
This is for use with Philips automation systems that
are unable to support the rich feature set of the
ARC.
This protocol only provides a limited number of
commands and is described in more detail on page
4.53.
The full Snell and Wilcox protocol is widely used
and is freely available from Snell and Wilcox.
