PERATION
The 8X40 LCD is the standard display for the 562 and 662 controllers. A
16X40 LCD is available as the primary display for the 663 and 665
controllers. Both displays interface to the same factory-installed LCD
driver board as shown in Figure 2-19 and Figure 2-20.

ARDWARE
The LCD driver board is installed on new indicators at the factory.
Jumpers E2 and E3 are both set to match the display size (SM = 8X40
LCD; LG = 16X40 LCD) as shown in Figure 2-21.

Connections to the LCD driver board are the LCD interface ribbon cable
(J3) and the LCD backlight (J4).

A low-tone, variable speed warble will occur at power-up if the LCD
driver board is installed but the display is not connected to J3.

ARAMETER
The LCD driver board is auto-detected at power-up. Once detected, the
LCD is automatically selected as the primary display. Therefore, it is not
possible to use the 7-segment VFD or 4X20 VFD with the LCD connected.
Model 660 Series controllers that use the LCD will have P425 set to "
Alwys
", indicating that the LCD display will always be used as the
primary display when the driver board is installed.

Although it is possible to connect a 4X20 VFD while using an LCD, there
are several issues that complicate simultaneous use of both displays:
•
It would not be possible to use macro commands to transmit data to
the 4X20 VFD as they will instead be automatically routed to the LCD.
