This section describes how to use the ancillary functions of the LDS4.
7.1
Configuring the Page Select Mechanism
The screen page select is operated via the screen page analogue input or via a CAN message.
To configure the CAN message for screen page change, select Setup | Controller... to show the
controller setup dialog:
Specify the message type (standard or extended) of the page select message and the CAN ID
code of the message.
The format of the CAN message code can be set to either 16/32 bit or 11/29 bit using the radio
button at the foot of the window:
·
11/29 bit CAN code assumes the arbitration code for the message occupies the bottom 11
bits of a 16 bit standard CAN code or the bottom 29 bits of an extended CAN code.
·
16/32 bit CAN code assumes the arbitration code for the message occupies the top 11 bits of
a standard CAN code or top 29 bits of an extended CAN code. This is used for compatibility
with AN82527.
The screen page should be encoded in byte 3 (the 4th byte) of the specified CAN ID. For
example:
00 00 00 00 00 00 00 00 selects page 1.
00 00 00 01 00 00 00 00 selects page 2.
00 00 00 02 00 00 00 00 selects page 3.
---
00 00 00 0A 00 00 00 00 selects page 11.
00 00 00 0B 00 00 00 00 selects page 12.
---
00 00 00 0F 00 00 00 00 selects page 16.
When the display is powered up, it checks the analogue page select input to determine which
page to show. If nothing is connected to the analogue input, it starts at page 1. The page changes
in response to any of the following:
·
The page number indicated by the analogue page select input changes.
·
A page number on the page change CAN message changes.
