Keep the following guidelines in mind as you design your system:
l
Make sure that the maximum cable length between any two DataMan 360 readers or between the PC and any
DataMan reader is no greater than 15 meters.
l
There is no fixed limit to the number of DataMan 360 readers that you can connect to a single PC. Each reader
introduces a delay of about 100 ms when it retransmits received serial data. If you have 5 readers, this means
that there will be a 400 ms delay between the time the first reader in the chain transmits data and the PC receives
it.
l
Each DataMan 360 reader must receive a hardware trigger signal on its Input 0 line. You can wire the input ports
to a common trigger signal or you can provide individual triggers for each reader.
l
Each DataMan 360 reader must be individually configured for multi-port operation, and you must perform this
configuration using a USB connection.
l
If
any
reader in the multi-port chain loses power or becomes disconnected, then no data from any other reader
will be transmitted.
l
If a DataMan 360 is transmitting its own read result, it will buffer any data received from another reader until it has
finished its own data transmission. If a DataMan 360 is transmitting another reader’s data, it will buffer its own
data if it receives a trigger signal while it is processing the other reader’s data.
l
If you use a single power supply for multiple readers, make sure that the power supply can provide enough
power for all of the readers.
