"Smarter Timing Solutions"
Chapter
Three
Console Port Control and Status
This chapter describes RTM3205 control and status commands used via the Linux console. The con-
sole is accessed via any of the Ethernet ports or the RS-232 serial port. RTM3205 supports several
application-specific commands for configuration and for monitoring the performance and status of
the Linux and GPS Subsystems.
You do not need knowledge of Linux commands in order to operate RTM3205. However, RTM3205
does support a subset of the standard Linux commands and utilities and it uses the
bash
shell, which
is the Linux standard, full-featured shell. A wealth of information is available from a variety of other
sources on Linux.
RTM3205-specific commands will be described in this chapter. For a brief description of some of the
most useful Unix/Linux commands, see
Appendix C - Helpful Linux Information
.
Console Ports
Three interface ports are available on RTM3205. Two are 10/100/1000Base-T Ethernet ports and one
is an RS-232 serial port. Network cables and a serial cable are provided with each RTM3205 ship-
ment. The serial cable is wired as a null-modem adapter and can be used to connect RTM3205 to the
serial port on your computer. Detailed specifications on the ports, including the RS-232 pinout, are in
Appendix K - Specifications
.
General Linux
Operation
You do not need to know Linux in order to operate RTM3205. However, for those interested, the
command shell used by RTM3205 is the Linux standard:
bash
. All commands and file names are
case sensitive, which is standard for Unix-like operating systems. For a brief description of some of
the most useful Unix/Linux commands, see
Appendix C - Helpful Linux Information
.
If you are unfamiliar with Unix-like operating systems, and you would like to be able to more closely
monitor or optimize the performance of your RTM3205 then you should consult good Linux refer-
ence books or the Linux Documentation Project at::
