Lectrosonics PT3 - Manual (Page 19)

command ECHO ON so you can see what you’re typing. Then enter SHOW DEVICE to see the list of connected
devices. The Lectrosonics Translator should appear in the list. On older masters, it may appear as an unknown device
type, recognizable as the PT3 from its AXlink device number. The PT3 will work properly even if it is identified only as
an unknown device by the AMX master. The important thing is that the master must detect the device with the device
number selected in step 2.
15. To test the actions, enter the command
PULSE [ N,1]
where N is the AXlink device number selected in step 2 (e.g. PULSE [161,1]). This pulses channel 1, thus performing
the Auto/Direct Remote action. The AM8 is now prepared to accept Auto vs. Direct channel settings from the
LecNet.
16. Now enter
PULSE [ N,3]
again substituting the AXlink device number for N. This pulses channel 3, thus performing the Auto/Direct All Direct
action. This sets all AM8 channels to direct mode, causing all 8 front panel LED channel status indicators to illumi­
nate.
17. Next, type in
PULSE [ N,4]
again substituting the AXlink device number for N. This pulses channel 4, thus performing the Auto/Direct All Auto
action. This sets all AM8 channels to auto mode, extinguishing all 8 front panel LED channel status indicators.
18. To test the monitoring capability, first enter
PULSE [ N,2]
where N is the AXlink device number selected in step 2. This pulses channel 2, thus performing the Auto/Direct
Local action. The AM8 again accepts Auto vs. Direct channel settings from the rear panel dipswitches, rather than
via LecNet commands.
19. Now enter
DEVICE STATUS N
where N is the AXlink device number selected in step 2. The list of channels which are on from 101 through 108
should correspond with the LEDs on the front of the AM8 mixer. From here, each time you press the Enter key, the
AMX master will repeat the last command, allowing you to continually monitor the status of those channels. Using the
AM8 rear panel dipswitches, try switching some AM8 inputs between auto and direct mode. The status of AXlink
channels 101-108 as reported by the AMX master should track with the LEDs on the front of the AM8.
If any of the above doesn’t work correctly, please refer to the TROUBLESHOOTING section.
20. Congratulations! You are well on your way to mastering a very powerful and sophisticated one-of-a-kind tool,
which makes some previously difficult tasks much easier and previously impossible tasks possible.
AXCESS PROGRAMMING HINTS
The topic of programming AMX control systems is a broad one which is well beyond the scope of this manual. There
are nonetheless a few hints we would like to offer. Working examples featuring all of these practices are included on
the distribution disk that comes with the PT3.
PULSED VS. LATCHING CHANNELS
Commonly a channel will be “pulsed” to perform a single task. A good example would be the use of separate buttons
on a touch panel, one to “mute” a mixer input, the other to “unmute” it. When the button is pressed, the PT3 will see
