Figure 3-39 Serial Setup Screen 3 of 3, CAN
This screen is for programming the CAN connector on the rear panel of the exciter. This
window became available with APEX exciter software versions 5.2 and later.
The exciter CAN bus is used with the PowerCD transmitter and with some earlier Diamond
and SigmaCD transmitters.
• The CAN ID is selectable between Exciter A and Exciter B.
• The Baud Rate is as follows:
Default is 125 kHz
Rate for Diamond and SigmaCD transmitters is 133 kHz
Rate for PowerCD transmitter is 250kHz.
• The Tx Frame Rate is as follows:
Default is 1Hz
Rate for PowerCD, Diamond and SigmaCD transmitters is 2 Hz.
Improper Baud or Tx Frame rates will lock up the CAN bus. The solution to this problem
is to set the rates correctly, or in the case of Diamond or SigmaCD transmitters the CAN
cable may be unplugged form its connector on the rear of the exciter. The exciter CAN bus
cables have been removed on current productions of Diamond and SigmaCD transmitters.
The Baud and Tx Frame rate windows are normally greyed out (locked). To unlock these
windows and set the two rates perform the following.
1 Go to the Home > Setup > Exciter > Transmitter select window and set the selection
to Custom, then click done.
2 Return to the Serial Setup 3/3 CAN screen (Home > Setup > Serial I/O > Serial Setup
3/3 CAN) and change the two rates.
A Click in the appropriate window, use the up or down arrows to select the cor-
rect rate, then click on Done.
3 Return to the Home > Setup > Exciter > Transmitter window and set the correct trans-
mitter choice, then click done.
