- Emerson Remote Terminal Unit Instruction Manual

3-10 / Service CI-ControlWave Express
• CPU/System Controller Board Switch SW2-8 must be OFF to run the WINDIAG
program. Setting SW2-8 OFF will prevent the ‘Boot Project’ from running and will place
the unit into diagnostic mode.
• Any ControlWave Express communication port can be connected to the PC provided
their port speeds and configuration match, e.g., baud rate, parity, stop bits, protocol, etc.
This can be accomplished via user-defined Soft Switches.
• Setting CPU/System Controller Board Switch SW2-3 OFF will force ports COM2 and
COM3 to 9600 baud, 8-bits, no parity, 1 stop bit, BSAP/ControlWave Designer protocol
operation.
• Communication port COM1 is only forced to 9600 bps operation when CPU/System
Controller Board Switches SW2-3 and SW2-8 have both been set OFF. COM1 can also
be set to 9600 bps operation via user defined Soft Switches.
• Setting CPU/System Controller Board Switches SW2-3 and SW2-8 OFF prevents the
‘Boot Project’ from running, places the unit into diagnostic mode and forces
communication ports COM1, COM2 and COM3 to operate at 9600 baud.
COM1: From the factory, RS-232 Communications Port COM1 (9-pin male D-type connector
J4, or 3-pin male connector J11) on the CPU/System Controller Board defaults to
115.2 kbd (RS-232) using the BSAP Protocol. Note: Port COM1 will be configured for
RS-232 operation (at 9600 baud) by setting CPU/System Controller Board
Switches SW2-3 and SW2-8 OFF. This will prevent the boot project from running
and places the unit into diagnostic mode. CPU/System Controller Board Switch
SW2-8 must be set OFF to run the WINDIAG program. Connection to a PC requires
the use of an RS-232 “Null Modem” cable (see Figure 2-5A).
COM2: From the factory, RS-2325 Communications Port COM2 (8-position Terminal Block
TB3) on the CPU/System Controller Board defaults to 9600 baud, 8-bits, no parity,
1 stop bit, BSAP/ControlWave Designer protocol operation (RS-232).
COM3: RS-232/RS-485 Communications Port COM3 (5-position Terminal Block TB4) on
the CPU/System Controller Board defaults to 9600 baud, 8-bits, no parity, 1 stop
bit, BSAP/ControlWave Designer protocol operation. In lieu of the use of an RS-232
Port, an RS-485 cable (see Tables 2-3B & 2-4) can be connected between COM3
and a PC’s RS-485 Port.
To use the WINDIAG program place any critical processes under manual control.
WINDIAG cannot be run while the ControlWave Express application is running. Set the
CPU/System Controller Board Switch SW2-8 to the OFF position. Perform steps 1 through 6
below.
1. Start the OpenBSI NetView Program. A screen similar to Figure 3-6 will appear.
2. To start WINDIAG program, click on Start Æ Programs Æ OpenBSI Tools Æ
Common Tools Æ Diagnostics.
3. Once WINDIAG has started, the Main Diagnostics screen of Figure 3-7 will appear.
