System Block Diagram
Figure 2.1 shows how a PC (using AnaWin3) interfaces with
the PPC-2000 controller. Refer to the PPC-2000 User’s Guide
for specific wiring and configuration information.
Figure 2.1 Connecting One PPC to a
Computer Using RS-232
Communication with a single PPC-2000 controller can be made
using an RS-232 connection to one of the PC’s serial ports.
RS-232 cables are available from Watlow Anafaze.
The serial communication link required to communicate with
more than one Watlow Anafaze controller or with a commu-
nication cable longer than 50 feet is RS-485. We recommend
using the standard serial interface of RS-232 with an external
RS-485 converter.
We recommend using a B&B Electronics RS-232/RS-485 op-
tically isolated converter P/N 485OIC. This converter has
screw terminals for connecting the RS-485 wires and a DB-25
male connector for the RS-232 side. You can reach B&B Elec-
tronics at (815) 434-0846.
Contact the factory for other available converters.
Safety
Watlow Anafaze has made every effort to ensure the reliabil-
ity and safety of its controllers and AnaWin3.
Good engineering practices, electrical codes, and insurance
regulations require you to use independent external safety de-
vices to prevent potentially dangerous or unsafe conditions.
