* must correspond to the values defined by the factory-installed 0-coding resistors on the module.
EXAMPLE
You can read the Status register:
in 84
The following text is displayed:
84=23
23 (hex) means that
— bit 5 is on (meaning no need for EMD FPGA)
— bit 1 is on (meaning a certain PCB version)
— bit 0 is on (meaning no emulator jumper = normal condition)
These values are displayed in hexadecimal notation.
5.6.6 MSGR - Message read (D)
This command alters the functionality of the Multifunction Vehicle
Bus. Consider the operative situation carefully before using this
command on board a train.
SYNTAX
MSGR
EXPLANATION
With this command you may read the unread messages from the receive queue. Refer
to command MSGS - message send (page 34). This test function tests the event
polling and message data queuing mechanism by sending messages and reading the
receive queue of the destination device. You may also send messages to the MVB
module itself. Again, refer to command MSGS. These test messages have nothing to
do with TCN messaging. This command is marked D because reading the messages
removes them from the receive queue.
