EM2218C is a digital sound repeater capable of playing Windows .wav sounds. It is directly compatible with
uncompressed 8-bit mono PCM sound files digitized at 8, 11, 16 or 22 KHz. Sound programming is as simple as copying .wav files to the flash card via a reader device attached to the computer. CompactFlash cards, commonly
used in digital cameras, are readily available in many different capacities. Hundreds of tracks with more than an hour’s worth of audio can be recorded onto a single flash card.
Since .wav files can be used directly
for playback
without going through any conversion and/or compression, EM2218C offers cleaner and better sound than other digital repeaters. Most other file formats (such as MP3 and WMA) incorporate data compression at the cost of lower sound quality. With the cost of flash cards being so low, compressed file formats just don’t make sense in most industrial applications.
EM2218C can be easily configured to work in different modes of operation. The most powerful mode, the Script Mode, allows you to define a script of playback steps for each trigger. For example, you can play a file, wait
a few seconds, play another file, then jump to another script. Or you can put the unit into an endless play loop which may be interruptible or non-interruptible.
Designed to be a stand alone
device, EM2218C can be powered by a single voltage power supply, and output to a speaker directly. Sound playback can be activated by a number of devices such as push buttons, motion sensors and PLCs. Standard interfaces include a RS-232 serial port and eight contact closure inputs. Keypad and other custom interfaces are available by special request.
