MPRX
TransCore Proprietary 5–3
Command Response Conventions
Like the MPRX commands, responses are preceded by the # character. Many MPRX
commands respond with
#Done
or
#Error
indicating the command was or was not
recognized and completed. Other commands respond with a four-character identifier
followed by one or more values.
Table 5 – 2 shows an example of a command/reply sequence. This example assumes
that an MPRX with serial number SN97001P running version X.XX software is connected
to a PC running a terminal emulation software package such as Windows Hyper Terminal
or Procomm Plus. The command sequence verifies that communications are working
correctly.
Table 5 – 2 Sample Command Sequence
In command discussions, MPRX response characters may be shown in brackets < >.
The use of brackets indicates that the response is a value in the range of characters.
The brackets are not part of the response. For example, the response to command
#520
Display Power Fail Bit is either a 0 or a 1. In the command discussion, the
response is shown as:
#PWRB <0-1>
with actual MPRX response being one of the following:
#PWRB 0
#PWRB 1
In this example, PWRB is the four-character identifier for power fail bit , and the 0 or 1 is the
value. All spaces shown in the response are actual spaces sent from the MPRX. In this
example, one space is between the letter B and the number.
Operating Parameters
The MPRXs maintain their operating parameters in nonvolatile memory (NVRAM) so that
the parameters are preserved after a power-down sequence.
