Memory Guidelines
Refer to the memory guidelines listed below when you develop Interact
applications. The following table lists guidelines to follow concerning the
use and capacity of memory used for runtime and development systems.
Available Connectors
The P1 PowerStation includes many of the same ports found on most PC’s.
All P1 PowerStations have two serial ports, a parallel port, a PS/2 style
keyboard/mouse port, and an Ethernet connector. The following graphic
shows the available connectors on a typical P1 PowerStation.
Serial Ports
The P1 PowerStationhas two serialports you canuse tocommunicate with
external devices at baud rates of up to 115 Kbaud. COM1 supports RS-
232C, while COM2 supports RS-232C, RS-422, and RS-485 communica-
tion standards.
Memory Capacity
DRAM 4MB standard; up
g
radable to 16MB. 4 MB will run
APM, PTM runtime modules and 2 drivers.
Flash Drive 4MB standard; additional flash drives are available.

The communication standard you select for COM2 depends on the
distance between the PowerStation and the controller as well as the
communication standardsthat the controller supports. Use a standard DB9
connector for communicating with this port.
Note If you are using RS-232-C communications, the length of the serial
cable should not exceed 50 feet (15 meters).
RS-422 and RS-485 communications offer greater noise immunity than
RS-232-C. These standards increase the maximum cable length to 4000
feet (1200 meters).
RS-422 communications are full-duplex (can send and receive simulta-
neously) while RS-485 communications are half-duplex (can only send or
receive at one time).
For either configuration, be careful not to connect any wires to unused
connector pins. Information on the specific connection required for the
Interact driver you use is located in the Help file associated with the driver.
COM1 pinouts
If you need to make a cable for communicating with COM1, the following
table shows the pinouts and signal information for this port.
COM2 pinouts
If you need to make a cable for communicating with COM2, the following
table shows the pinouts and signal information for this port. COM2 is set
to the RS-485 protocol by default. To change COM2 to the RS-232-C or
RS-422 protocols, you must change the COM2 DIP switch settings.

COM2 DIP switch settings
If you need to make a cable for communicating with COM2, you also need
to set the DIP switch settings for this port. The DIP switch for COM 2 is
located on the top of the PowerStation Unit, as shown in the photo below.
The following diagram shows the settings for this port. A similar diagram
is located on the PowerStation itself next to the DIP switch. COM2 is set
to the RS-485 protocol by default. To change COM2 to the RS-232-C or
