Title: syren10
Post by: karmax on February 19, 2009, 04:47:55 AM

hi guys... We are trying to communicate with two syren 10 where s2 is controlled with a microcontroller and s1 is the data given directly from a computer (thru a max 232). This arrangement works fine when only 1 driver is placed on the bus but as soon as 2 drivers are placed we can not control both of them independently i.e. either both are on or off.
Please suggest some measures

There are several ways to do this . . . for example:

Your PC probably has several USB ports. Buy two USB to TTL adapters, and use one for each Syren 10.

In simplified serial mode, the s2 input can be used to select the drive that is to be commanded by the serial message. 0V=ignore, 5V=accept.
Another option is to use packetized serial mode which can address individual drives without using the s2 line.  The drive address is contained in the serial message.
I like packetized serial mode since there is better resolution for the commanded speed.
