View and Change the PPO
On the front-panel display traverse to the Main Menu and then to CPU_I/O. This display lists any
connector on the CPU Module that has an optional I/O signal. Connectors are identified as A, B or C.
Select the particular connector (I/O-A, I/O-B or I/O-C) to see which signal is installed. To change the
PPO pulse rate press EDIT.
Or, you can use these console port commands:
Command:
cpuio
Sonoma reply:
PROGRAMMABLE PULSE OUTPUT is Installed
Current Setting = OFF
Command:
cpuioconfig
Sonoma reply: Interactive script is started so you can change the pulse rate.
1PPS Output
This output provides 1PPS signal. There are several variations of the 1PPS Output signal such as:
1PPS TTL, 1PPS (RS-422), and Inverted 1PPS. The Programmable Pulse Output also has a 1PPS
selection.
The 1PPS is a “system signal”. This means that there is one 1PPS signal that affects the whole sys-
tem. In other words, if your Sonoma has multiple 1PPS outputs and you change the pulse width, then
all 1PPS outputs will be affected.
The pulse width is normally 1 millisecond wide when shipped from the factory but can be changed
(see below). For details on the 1PPS signal definition see Appendix H - Specifications .
View the 1PPS Connector
On the front-panel display traverse to the Main Menu and then to CPU_I/O. This display lists any
connector on the CPU Module that has an optional I/O signal. Connectors are identified as A, B or C.
Select the particular connector (I/O-A, I/O-B or I/O-C) to see which signal is installed.
Or, you can use this console port command:
Command:
cpuio
Sonoma reply:
CPU I/O B - 1 PPS OUTPUT is Installed
Current Setting = (See systemio command)
Change the 1PPS Pulse Width
On the front-panel display traverse to the Main Menu and then to Sys_I/O. If a 1PPS output is
installed in your unit, then there will be a selection for 1PPS_Out. Select this and you will be able to
choose from among these pulse widths: 20 microseconds, 1 millisecond, 100 milliseconds and 500
milliseconds.
