WINDIAG program, it must not otherwise be in use. Note: CPU Switch SW2-8
must be set OFF to run the WINDIAG program.
COM3: RS-232/RS-485 Communications Port COM3 on the CPU/System Controller Board
defaults to 9600 baud, 8-bits, no parity, 1 stop bit, BSAP/ControlWave Designer
protocol operation. CPU/System Controller Board Jumpers W12 through W16 are
used to configure COM3 for RS-232 or RS-485 operation (1-2 = RS-232, 2-3 = RS-
485) and Switch SW3 is used to configure COM3 when it has been set for RS-485
operation (see Table 2-5). To test COM3 using the WINDIAG program, it must not
otherwise be in use Note: CPU/System Controller Board Switch SW2-8 must be set
OFF to run the WINDIAG program. 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 the PC’s RS-
485 Port.
2.4.5 Optional Display/Keypad Assemblies
Three Display/Keypad assemblies are offered; one with a dual-button Keypad (see Figure 2-
29 one with a 25-button Keypad (see Figure 2-30 and one without a Keypad (see Figure 2-
28). Both Display/Keypad assemblies utilize identical 4 x 20 LCD Displays. The Display
ONLY assembly contains an upper row consisting of a ± LCD character along with nine 7-
Segment LCD characters, and a bottom row consisting of six 14-Segment LCD characters.
LCDs Each Display/Keypad or Display only assembly employs a unique microcontroller
based Display/Keypad Interface Circuitry (situated on the remote Display or
Display/Keypad assembly that drive the LCD Display and interfaces the Keypad (when
present). Interface to the ControlWave Express is made via a cable equipped with two
plugs. This cable connects to the RJ-45 Display Jack (J2) on the CPU/System Controller
Board and RJ-45 Jack (J1) on the remote Display or Display/Keypad assembly. A
potentiometer is provided on the Display or Display/Keypad to set the contrast of the LCD
Display.
Figure 2-29 provides mounting hardware information for the Dual-button Display/Keypad
Assembly. Operation of the Display Only Assembly is briefly discussed in section 2.4.5.1.
Operation of the Dual-button Display/Keypad Assembly is discussed in section 2.4.5.2.
Figure 2-30 provides mounting hardware information for the 25-button Display/Keypad
Assembly. Information on configuring the ‘Display Function Block’ (required to configure
the Display associated with the 25-button Display/Keypad Assembly) is provided in
ControlWave Designer’s On-Line Help.
Note: Operation of the 25-button Display/Keypad Assembly is discussed in
Appendix E.
2.4.5.1 Operation of the Display Only Assembly
In normal operation, the display stays on after the unit has been configured and placed into
service. ControlWave Express Display ONLY assemblies contain an upper row consisting of
a ± LCD character along with nine 7-Segment LCD characters, and a bottom row consisting
of six 14-Segment LCD characters. Signal values controlled by the application are posted to
the upper characters and signal names are posted to the lower characters.
