<CR>
Response: OK<CR><LF>
The Serial/Network port will respond with the message “ERROR 01 VALUE OUT OF RANGE” if the
input string was in the correct format but contained a value, probably numeric, that was out of the range
of acceptable values.
The Serial/Network port will respond with the message “ERROR 02 SYNTAX” if it receives a string in an
incorrect format.
The Serial/Network port will respond with the message “ERROR 03 BAD/MISSING FIELD” if the input
string lacks a required field.
F111 – J2 Output (Rate, PPO)
Use function F111 to configure the J2 Output to generate rates (listed below), or as an option, to
generate Programmable Pulse Outputs (PPO). The following rates are available as a standard feature:
1 PPS, 10 PPS, 100 PPS, 1 kPPS, 10 kPPS, 1 MPPS, 5 MPPS, 10 MPPS. The default factory setting is
10 MPPS.
For J2 specifications, see “J2 Output – Rate Out or Programmable Pulse Output” on page 10
.
Notes on F111 PPO:
• PPO is an optional feature. If purchased at the same time as the XLi, it comes enabled on the
system. To purchase this option after you have purchased the XLi, contact Symmetricom Sales.
See “H: Sales and Customer Assistance” on page 295.
• PPO can provide a single pulse output or repetitive pulse outputs.
• PPO can start and stop the pulse at any time in the year, with a resolution of one microsecond.
• The repetition rates from PPO are based on “wildcards”. See “Repetitive PPO pulse outputs” on
page 144 regarding usage of “wildcards” to specify PPO repetition rates.
• PPO can provide the following sub-second repetition rates: 100 PPS, 10 PPS, 1 PPS, 100 PPS,
and 10 PPS.
• If PPO only specifies one time, it is the start time. The stop time is automatically set for one
microsecond later.
