Send Delay
- This can be ticked if the device requires a minimum delay between commands being
sent.
If a script has been loaded for a device then the
script will set the Reply Timeout and Send Delay settings
automatically
. These can however be changed manually if required.
Acknowledgements, errors etc. for devices can be viewed on the monitor panel with
Com
selected
(see "Com", p.157).
The Sanyo projector can also be controlled via an IP connection so two buttons are enabled -
RS232
and
IP
. If you are using an IP connection to the device then clicking on the
IP
button will
change the
RS232 / IP Settings
area enabling you to set how many of these units are connected and
the IP addresses for each. The last box - set to the default of
0
- is the IP port number that some
devices require.
With the RS232/IP properly configured, ShowMagic can send commands to the external devices
using control events (see "Using RS232 or IP Controllable Devices", p.144). Similarly, any events
can be assigned to action buttons and these action buttons can be triggered on receipt of command
strings received from external RS232 devices (see "Triggering Action Buttons", p.167).
Using Device Scripts
The commands for controllable devices are varied, numerous and can be cryptic or lengthy, so for
speed and ease of programming ShowMagic device scripts include ‘generic’ control codes for the
most commonly used control commands, e.g.
Play
,
Rew
,
Stop
etc. In this way you don’t have to
keep referring to the command protocol for the device to find the correct string commands to enter
for the most commonly used commands, you simply use the
Command
drop-down menu on the
Enter Ctrl String
dialogue to see what generic codes are available for that device and select one of the
‘Plain English’ codes - ShowMagic does the rest for you. ShowMagic actually converts the generic
control codes into the correct string commands / numbers required by that device then sends those
strings, in the right order, to the device.
ShowMagic scripts will be made available for more and more devices as time goes by, but if you
wish to have a particular device included then please get in touch with AVSS supplying the details
of the device and we will do our best to make a script available for it.
Using Data Acquisition Devices
Action buttons can be triggered / controlled (see "Triggering Action Buttons", p.167) using data
acquisition ‘input’ devices such as ADAM digital input modules and PISO813 analogue input cards.
Other trigger options include system devices such as joystick / joypad buttons and key presses (or
any external devices that simulate these).
A script can be loaded (as described above) for these other ‘input’ devices using the
Configure
Comm Devices
dialogue box and if any of these devices do not use a com port then the com
settings are not used.
The
Device
Polarity
drop-down menu is enabled if you are using digital input data acquisition
devices such as ADAM modules.
