routes messages from the drives back to the host PC or PLC. In Router Mode, the
indexer-drives are commanded and queried using SiNet Command Language (SCL).
Router Mode is the most versatile way to use the hub, but also the most difficult
because you’ll need a highly skilled programmer to write your host software.

✔
at least one
Si™
step motor or servo motor drive
✔
a motor for each drive
✔
a small flat blade screwdriver for tightening the connectors - an Applied Motion
Products screwdriver suitable for this purpose is included with your drive.
✔
a 5-24 volt DC power supply may be required to use the isolated I/O
✔
a PC running Windows 95, 98, 2000, ME, NT or XP with an unused 9 pin serial

✔
a PC serial interface cable (it comes with your Si™ indexer/drive)
✔
a modular telephone line cord for each indexer/drive (the hub comes with one 7
foot cable, and each drive includes a 7 foot cord. You can get longer cords any-
where telephone cords are sold, such as your local supermarket, discount store or
Radio Shack)
✔
your own custom software to command and query the indexer/drives using
Si™
Command Language (SCL)
. This means you need a highly skilled computer
programmer working with a language system like C, Visual Basic or Labview.
