Basis for the communication with attached devices are the channels. A channel gives access to a physically interface - e.g. a RS232 port or a UDP port. The device drivers use these channels to communicate with the devices attached to the channels. A channel is assignable to more than one device. This is useful for bus devices (the control cable is daisy-chained) were each device has an individual address. Also, one device can have more than one channel. This is useful if e.g. two or more player should start at the same time (in sync). In this case, one command is sent to all needed channels at the same time. Note: This feature is available in Pro and Ultimate version only.
If one device accessing a channel, it is blocked as long as the access is finished. This is very important in multi task systems, because two devices can not use the same resource at the same time.
Via main menu Configure - Channels (or Icon iconchannelsetup ) the channel editor opens. Every channel is identified by its Channel Name. For that reason, not only interface parameters are needed to specify the channel, but also a unique channel name. The channel name should (but is not required) give a hint on how the channel is used. E.g. a channel used to control a DVD player could have the name “dvd1”, the channel for the second DVD player is named “dvd2” and so on. We recommend to name the channels in lower case letters, and the Devices with a leading upper case letter.
Before creating a new channel, it is necessary to specify its kind in the Interface Type area and enter a channel name as described above. To edit a channel, select its name in the left list and change its parameters. Then click Update Channel.
Serial channels are used for RS232/422 and 485 interfaces. Get Serial List loads all previously scanned ports in the Port: list. If new serial ports attached to the system, Refresh executes a new port scan. On systems with many serial interfaces this could take a while.
