2.4.2.3 Remote Upgrade of ControlWave Express Firmware
It is possible to download system firmware into an unattended remote ControlWave
Express. This function can only be accomplished if CPU Board Switch SW2-6 (associated
with the unit in question) is set in the ON position (factory default). The procedure for
performing a remote download of system firmware is discussed in Appendix J of the Open
BSI Utilities Manual (document D5081). Note: Remote upgrade of ControlWave
Express Firmware requires Boot PROM version 4.7 or higher and System PROM
version 4.7 or higher.
2.4.3 Operation of the Mode Switch
The CPU/System Controller Board’s Mode Switch (SW1) is a four position DIP-Switch;
functions are listed in Table 2-12.
Table 2-12 - CPU/System Controller Bd. Mode Switch SW1 Assignments
Recovery Mode/Local Mode Control
SWITCH Function Setting
SW1-1/2 Recovery/Local Mode
Both ON or OFF = Recovery Mode
SW1 OFF & SW2 ON = Local Mode
SW1-3 Force Recovery Mode
ON = Force Recovery Mode (via CW Console)
OFF = Recovery Mode disabled
SW1-4 LED Status
ON = Enable All LEDs
OFF = Disable All LED except Watchdog (WD)
* = Note: Only the Switch SW1 settings listed in this table, have been tested.
Recovery Mode
: Recovery Mode is used for either a firmware upgrade (see Section 2.4.2) or
a core updump (see Section 3.6).
Local Mode
: Local Mode should be selected for normal running operations.
2.4.4 Soft Switch Configuration and Communication Ports
Firmware-defined soft switches that control many default settings for various system
operating parameters such as BSAP Local Address, EBSAP Group Number, three (3)
communication port parameters, etc., can be viewed and, if desired, changed via the Flash
Configuration Utility, which is accessible from LocalView, NetView, or TechView. When
connecting the ControlWave Express to the PC (local or network) for the first time you
should be aware of the communication port default parameter settings provided below (see
Figures 2-5 and 2-6). Note: Communication port factory defaults can be enabled anytime by
setting CPU Board Switch SW2-3 to the OFF position. CPU Switch SW2-8 must be set OFF
to run the WINDIAG program.
COM1: From the factory, RS-232 Communications Port COM1 defaults to 115.2 kbd (RS-
232) using the BSAP Protocol. Note: By setting CPU/System Controller Board
Switch SW2-8 OFF, the boot project will be prevented from running and the unit
will be placed into diagnostic mode. To test COM1 using the WINDIAG program, it
must not otherwise be in use. Connection to a PC requires the use of an RS-232
“Null Modem” cable (see Figure 2-5A/B).
COM2: From the factory, RS-232 Communications Port COM2 on the CPU/System
Controller Board defaults to 9600 baud, 8-bits, no parity, 1 stop bit,
BSAP/ControlWave Designer protocol operation. To test COM2 using the
