The DM-Serial receives RS232 strings and converts these into 8 open collector outputs.
It also loops through the received RS232 for linking to other devices. It has four
modes of operation.
- Map Mode – using a single byte to set the state of all outputs.
- Mask Mode – using a single byte to change the state of a single output.
- Bit Mode – uses 2 bytes to change the status of a single output.
- Pea Mode – allows the use of arbitrary strings from 1 to 14 bytes for on & off
In all modes the outputs can be selected to either latch until changed or only give
a
1, 2 or 4 second pulse.
Software
The configuration software supplied, in addition to control and configuration,
also allows groups and zones to be created allowing a series of preset scenes to
be used
Applications
Modes 1, 2 and 3 require NO programming of the Serial Pea with the mode being selected
by jumpers, as is the selection of latched, 1 sec, 2 sec or 4 sec pulse. The host
controller will require programming with suitable strings for the mode of operation.
In Pea mode the strings can be user configured to follow a projectors On and Off
commands allowing the pea to be inserted into the serial cable from the controller
to the projector and use the Open Collector output to control relays for an electric
screen.
Specification
Power requirements 12V DC @ 25mA max.
Twin screw terminals are provide for ease of
loop through.
