Serial Line Amplifier
MultiCam
recommends using the Bravo Line Amplifier or a comparable serial line amplifier and requires a line
amplifier when the serial cable reaches or exceeds 100’. Not using the line amplifier will create communication
problems between the host PC and the
MultiCam
CNC machine as too much load will be placed on the Com
Port as well as on the Max202 chip of the
MultiCam
Controller.
The installation of the serial line amplifier involves the AC power adapter, line amplifier, DB25 female to DB9
male adapter, a 6’ adapter cable with a DB25 male connector and DB25 female connector, and a serial cable with
a DB9 male connector and DB9 female connector.
1. Flip the line amplifier over and make sure that the 2 switches are positioned towards the middle of the line
amplifier.
2. Place the DB25 male connector of the 6’ adapter cable into the “To DTE” end of the line amplifier.
3. Place the DB25 female connector on the other end of the 6’ adapter cable into an available Com Port of the PC.
4. Place the DB25 female end of the DB25 female to DB9 male adapter into the “To DCE” end of the line
amplifier.
5. Place the DB9 female end of the serial cable into the DB9 male end of the DB25 female to DB9 male adapter.
6. Insert the AC power adapter plug into the socket on the line amplifier and plug it into an AC outlet.
