Installation & Operation Manual

1. INTRODUCTION
This temporary addendum relates to the changes to the V1411A Video Switching System
compared with the original V1411 units. The contents of this addendum will later be
incorporated in a revised manual.
This addendum deals only with the changes from the original V1411 Video Switching
System and must be read in conjunction with the manual for that unit.
The new unit is essentially compatible with the V1411 but has a number of important new
features
•
The video loop outputs are buffered and need not be terminated if not used.
•
The connection arrangement has been improved with one RJ45 connector each for the
keypad network and the receiver network.
•
One local V1411X/J-DVC or V1410X-DVC keypad can be powered directly from the
Video Switching System via the RJ45 connector. If the local keypad is the only one on
the system it may be plugged directly into the matrix using an RJ45 to RJ45 lead supplied
without intermediate breakout boxes.
•
Alternative communications timeouts may be set up individually for receivers and
keypads.
The physical arrangement of the new connectors is shown in figure 1.
2. VIDEO LOOP OUT CONNECTIONS
The video loop out connections are now buffered. This feature solves a problem that arose in
some cases during the learn operation when devices that incorporated auto termination were
connected to the loop out outputs.
The video inputs are permanently terminated with 75 ohms and there is no need to
terminate unused loop out connections. The terminators that were provided with the
original V1411 are not now provided in the spares kit.
All video outputs – monitor and loop through - now have full push-pull outputs with virtually
no DC offset.
3. COMMUNICATIONS NETWORK CONNECTIONS
The 9 way D connector on the original V1411 is replaced by 2 off 8 way RJ45 connections.
One connector is used for the keypad network and the second for the receiver network.
Two off 2m RJ45 leads and two off breakout boxes are provided with the equipment.
3.1 Keypad Connections
3 possible keypad connection arrangements are shown in figures 2 attached
•
If a single, local V1411X/J-DVC or V1410X-DVC is used this may be connected directly
to the Video Switching System into the KBRD connector (see figure 1) using the RJ45

cable supplied with the unit or with the keypad. No breakout box is necessary. The power
for the keypad is derived from the V1411A. See figure 2a.
•
If a local keypad of one of the types mentioned above is used with other keypads its
power may be derived from the V1411A but two breakout boxes are necessary – one that
is provided with this unit and the other provided with the keypad – these breakout boxes
are physically identical but the connection arrangements are different – do not
confuse the two types. See figure 2b.
•
If types of keypads other than those mentioned above are used, there are no local keypads
or it is not desired to power a local keypad from the V1411A see figure 2c.
3.2 Receiver Connections
The receiver connection (other than for Vicoax 2) involves the use of an RJ45 lead and one of
the breakout boxes provided with this unit. See figure 3.
4. KEYPAD AND RECEIVER TIMEOUTS
The standard keypad and receiver timeouts are 4milliseconds. In some cases a remote keypad
is connected via a LAN or other data network and the delays are greater than the standard
timeout value. In this case a Comms Failure will occur either transiently or permanently.
The problem may be avoided with the V1411A by modifying the timeout values individually
for each keypad and receiver as required.
The modification of timeouts is carried out from Keypad 1 only using the dwell set functions
(see the keypad manual) and monitor numbers outside the physical monitor numbers of the
V1411A (maximum of 4 when the expander is fitted).
On the dwell set mode select the monitor number below then the figure set in the dwell time is
the timeout in milliseconds.
Monitor Timeout set for
11 Keypad 1
12 Keypad 2
13 Keypad 3
14 Keypad 4
15 Set keypad timeouts to default (but see below)
21 Receiver 1
22 Receiver 2
23 Receiver 3
. etc
.
36 Receiver 16
37 Set receiver timeouts to default (but see below)
When restoring keypad or receiver timeouts to default values the dwell must be set to
136 otherwise an error indication will occur and the values will not be reset.

The programme in the V1411A restricts timeouts to a minimum of 4mS and a maximum of
100mS.
It is essential the this feature is used with great discretion, only on individual devices
that require a larger timeout and the value used should not be greater than is necessary
to prevent Comms Failure messages.Failure to observe the above precautions can result
in significant degradation of the response to keypad operation. When in doubt consult
Vicon Technical Support.
5. LEARN OPERATION
The learn operation is carried out in the same way as on the original V1411 Video Switching
System. At the end of the learn operation, when pole 6 of the DIL switch is set to OFF, the
V1411A takes approximately 10 seconds to recommence normal operation rather than the 1
second on the original system.
