NAME
ptsctl - PTS Module Controller
SYNOPSIS
ptsctl [options]
DESCRIPTION
Set attenuation level on the Qualcomm Atheros Production Test System using a local RS-232 communication
port. The port settings must be configured before running this program. Settings are 9600 baud, no
parity, 8 data and 1 stop bit. See datasheet http://www.weedtech.com/wtssr-m.pdf for more information.
OPTIONS
-f file
The name of the serial port. On Linux, the name is usually "/dev/ttyS[0-4]". On OS/X, the name
is usually "/dev/cua[0-4]". On Windows, the name is "com[0-9]:". The default is "/dev/ttyS0" on
Linux and "com1:" on Windows. If environment string "PTSCTL" is defined then it takes precedence
over the default serial port. This option then takes precedence over either default.
-g attenuation
The desired line/ground attenation in Decibels. The value may be expressed in decimal, binary, or
hexadecimal. Binary varues start with "0b" and hexadecimal values start with "0x". The default
for this option is 127 dB.
-n attenuation
The desired line/neutral attenation in Decibels. The value may be expressed in decimal, binary,
or hexadecimal. Binary varues start with "0b" and hexadecimal values start with "0x". The
default for this option is 127 dB.
-p power
Turn on or off the Device Under Test power. The value of power can be 1=on or 0=off.
Alternately, keywords "on" and "off" can be used.
-r Read and display undecorated attenuator settings on stdout. Setting appear as two decimal
integers representing the attenuation in decibels. The line/neutral setting appears first then
the line/ground setting. This option is independent of options -n and -g. If this option is
present and the other are missing then settings are display but not changed. If this setting
appears with either or both of the other two then the settings are changed then read and
displayed.
-w wait
Wait time in milliseconds. Serial I/O operation are slow and a delay is needed after each write
operation. Unfortunately, different operating systems require different wait times. This options
lets you adjust the time. The default is 10 milliseconds which should be adequate on most
systems.
EXAMPLES
The following example turns the Device Under Test power on and configures the line/neutral attenuator for
72dB attenuation. Line ground attenation is automatically set to 127 dB since it is not specified on the
command line. Option -p is not necessary if the Device Under Test power is already on.
# ptsctl -p 1 -n 72
The next example configures the controller for 42 dB attenuation on line/neutral and 100 dB on
line/ground. There is no needed to turn the Device Under Test on again because it remains on until
turned off.
# ptsctl -n 42 -g 100
The next example configures the controller for 56 dB attenuation on line/ground and 127 dB on
line/neutral, and turns the Device Under Test off.
# ptsctl -p off -g 56
The next example reads the atteuator setting and displays them on decimal format on stdout. The
line/neutral setting appears first then the line/ground setting. In this example, line/neutral has 55 dB
attenuation and line/ground has 120 dB attenuation.
# ptsctl -r
55 120
You can also set the attenuation and read it back using one command. The next example sets line/neutral
attenuation to 10 db and line/ground attenuation to 50 db then reads the attenuator settings and displays
them in the standard order, line/neutral then line/ground.
# ptsctl -g 50 -r -n 10
10 50
