FAQ: Q: Where do I find a qualified A/V installer? A: Go to CEDIA (the Custom Electronics Design and Installation Association) to find the top folks in the field. Q: How do I control your switchers using RS-232? A: Lattis A/V switchers are typically integrated with RS-232 control systems from AMX , Crestron , Vantage Controls , RTI , and others, and computer-hosted systems such as lifeware , and Premise Systems . Two-way RS-232 communication provides both control commands and feedback messages. Parsing the returned messages is optional, but allows for a closed-loop system. The units may also be controlled using Infrared (IR) commands -- also, IR and RS-232 control may be used concurrently on the same switcher. If an IR command is used, the control system is immediately updated by receipt of a message (the same message that would result from the equivalent RS-232 command). A two-window Terminal by Bray (for win) is small and handy. Q: How do I use IR control? A: Lattis A/V switchers are typically integrated with IR (infrared) contol systems from RTI , Universal , Philips Pronto , and others. Lattis systems have support for infrared (IR) control when using a Vaux RC-16-IR remote control (or the earlier RC-8-IR). The RC-16-IR remote may be used to operate the system from the front panel sensor, or remotely via an IR repeater system connected to the rear-panel IR-In jack. The Lattis System can be controlled using one or more RC-16-IR remote controls, from different zones -- the zone code may be easily changed, allowing a remote to move from zone to zone. The zone number is embedded in the IR command, so there is an independent set of IR commands for each zone (up to 90 zones). All of the commands result in a single IR code (no macros). IR-Learning devices, such as in-wall keypads or remote controls, may learn the Vaux IR codes (typically for one zone) and also control the a/v system's source devices. Third-party IR code sets for several popular brands are available. Q: How do I control your switchers using Ethernet? A: Lattis A/V switchers may be ordered with the ethernet (-IP) option, and are typically integrated with Ethernet control systems from AMX . It is easy to add ethernet capability to drivers for most control systems. The control system simply opens a TCP/IP socket connection to the Lattis switcher, and then sends and receives using the exact protocol as used with an RS-232 connection. Our IP switchers may use dynamic (DHCP), or static ethernet addressing. For AMX applications, Vaux IP switchers provide complete Duet Dynamic Discovery. The Lattis product manual, and a full-featured AMX Driver, are stored in the switcher's ftp area -- the AMX driver controls up to 64-zones of audio and/or video switching, volume/bass/treble, presets, paging, and more. Two-way ethernet communication provides both control commands and feedback messages. Parsing the returned messages is optional, but allows for a closed-loop system. Vaux IP switchers are powered by powerful ethernet technology from Control Alternative Solutions .
