Serial Communication Overview; Controller Area Network (Can) Overview - PCS D200 User Manual

PCS D200 Dash Logger User Guide
In the case of pressure, the user can also select if the pressure is gauge or absolute. Pressure measured in gauge means
atmosphere pressure is equal to 0 kPa or 0 PSI. Pressure measured in absolute means atmosphere pressure is equal
to 14.7 for PSI and 101 for kPa. The units used for displaying a particular input are set by the particular function. Unit
changes, such as from Celsius to Fahrenheit, are global and will take affect on all temperature defi ned inputs.
The speed inputs can be defi ned as one of the following types on inputs.
• Frequency
• RPM
• Vehicle Speed
Similar to the analog inputs, the speeds can be given a more specifi c name and gauge.The dash's pulse-width modulated
(PWM) outputs are high side (+12VDC) drive outputs. These can be used for any of the following functions.
• Shift Light
• Output vs. Generic 16x16 Table
• Alarms
• Screen Override

1.1.2 Serial Communication Overview

Serial communication, also referenced as RS232, is used to connect serial devices to the dash. This includes many
after market engine management systems and the Garmin 5Hz GPS. Serial devices currently supported by the dash
include:
• AEM
• Autronic SMC, SM2, and SM4
• Electromotive TEC2 and TEC3
• FAST™ 1st Generation ECU
• Garmin 5Hz WAAS Enabled GPS
• Innovate Wideband
• Microtech
Only one serial device can be connected to the dash at a time. To connect a serial device with a standard 9-pin DB9
port, you must purchase the Serial ECU Connection Kit.
Serial devices are connected to the dash using a 9-pin circular connector to the Serial connection kit to the harness that
connects to the back of the dash. If communication is needed to the serial device using the manufacturer's software,
disconnecting the serial cable between the serial device and the dash is not necessary. Instead, the dash offers a Pass-
Through Mode that allows communication between a computer and the serial device. Pass-through mode connects the
serial port on the side of the dash with the serial device connected at the back of the dash. In this mode, the dash acts
as an extension wire, and the dash does not see the data transferring between the computer and the serial device. This
mode is selected Using the Communications button then selecting RS-232 from the Main Menu.

1.1.3 Controller Area Network (CAN) Overview

The Controller Area Network (CAN) is a high speed communication bus designed by Bosch as a reliable network to
withstand the harsh automotive environment. The following devices are currently supported.
• PCS Transmission Controller
• PCS Xtended Fuel Controller
• PCS Accelerometer Module
• PCS Exhaust Gas Temperature (EGT) Module x 2
• FAST™ XFI™ Engine Controller
• Dash Logger Expansion Module
• Motec M400, M600, M800, M880
