Software Option Bit Definitions
Bits are numbered from 0 to 31, from right to left. Currently, there are only two software options
defined in the Sonoma. These are for PTP/IEEE-1588 enabled on port 0 (eth0) or port 1 (eth1). The
table below shows the currently defined bits.

CPU Module Options
Standard rear-panel configuration for the CPU Module is the Antenna input, the RS-232 connector
and two Ethernet connectors. Refer to
Chapter 2 - Basic Installation, Sonoma Physical Description
for more information on the basic Sonoma rear-panel.
In addition to the standard connectors, the CPU Module can be configured with optional outputs.
Some of these optional outputs are a Programmable Pulse Output, a DDS Output, an Alarm Output,
various pulse rates at RS-422 levels, and a second RS-232 serial port with a Serial Time Output. See
sample CPU Module configurations below.

Programmable Pulse Output (PPO)
The PPO Option provides user-selectable, on-time pulse rates from 1 PPS to 10 MPPS. Other selec-
tions are 1PP60S (pulse per 60 seconds, on the minute), 1PP2S (pulse per 2 seconds, on the even
second), and Inverted 1PPS (falling edge on-time). For details on signal definition see
