2. Preparations for Operations
Up to 16 laser units can be controlled from a single personal computer. The
equipment conguration and connector connections are shown in the follow-
ing gure.
⇒
For controlling multiple lasers by single personal computer, it is necessary to reg-
ister equipment No. (NETWORK #) for each equipment. Set equipment No. with-
out duplication. If duplication of equipment No. exists, a data collision will occur
on the communication line and the laser cannot be correctly operated.
⇒
The RS-232C/RS-485 conversion adapter is an option separately sold. Purchase
it as required. For details, refer to the Introduction Part, Chapter 1 "Options" on
page 31.
⇒
Prepare the program and its development environment for laser control on the
customer side.
⇒
It is recommended to use the shielded cable. To exhibit the shield eect, connect
the shield of a cable to FG (frame ground) inside the laser equipment. Do not
use it as SG (signal ground).
