1 Introduction
This document is the User’s Manual for the EPSILON Switch and Amplifier System 17E and the
EPSILON Switch and Amplifier System 36E. (Unless otherwise indicated, details contained
herein apply to both models.)
The SAS-E achieves redundant Time & Frequency source monitoring with intelligent and
automatic switching. It amplifies signals from the selected source and offers a large quantity of
output channels. The SAS-E receives, and monitors continuously, signals from 1 or 2 external
clocks:
• Frequency sine wave signal (from 1 MHz up to 16 MHz)
• IRIG B DCLS or 1 pulse per second time synchronization (1PPS/DCLS TTL/50Ω)
• Time Of Day message (RS232C serial line)
• External clock status (relay contact)
• External signals* (External Sig)
Monitoring results (lost signal and minimal period detection) are reported to the user through
dedicated LEDs and through an Ethernet port. When 2 external clocks are connected, the
SAS-E offers a powerful redundant function by selecting, automatically, the better source. This
automatic selection may be by-passed by the user to allow maintenance or for single clock
operation.
In all cases, the distributed signals — Frequency, 1 Pulse Per Second (PPS), Time of Day
(ToD) — are issued from the same source clock. In automatic mode, when the current selected
source is detected faulty, the SAS-E switches all the distributed signals to the other source. An
Ethernet port allows managing and controlling the SAS-E through embedded SNMP protocol
and/or web server.
The SAS-E is available in two heights to adapt the output capacity to the user’s requirements:
SAS17E — 1u High Version:
8 x frequency outputs, 8 x 1PPS/DCLS TTL outputs, 2 x ToD outputs, 2 x external signals.
SAS36E — 2u High Version:
16 x frequency outputs, 16 x 1PPS/DCLS TTL outputs, 2 x ToD outputs, 2 x external signals.
*This External Signal input : this feature can only do the redundancy function, not multiply the distributed
signal.
Example : you can input 2 x IRIG RS485 and output 1 x IRIG RS485 with redundancy.
Note about the limitation of this feature : this signal input is not monitored by SAS E (SAS E doesn’t
analyze the presence nor the quality of the “External Sig” input signal to use it as criteria for switching).
So if you want to make the SAS E switches, you will need to use other inputs in addition (like alarm
contact or 1PPS/10MHz or RS232/TOD signal input).

Pinout description, DC connector
• Pin B goes to the most positive DC voltage of the DC source. For +24/48 V this would be
the positive output from the DC source. For a -24/48 VDC source this would be the
ground or return of the DC source.
• Pin A goes to the most negative voltage of the DC source. For +24/48 V this would be
the ground or return output from the DC source. For a -24/48 VDC source this would
be the negative output from the DC source.
• Pin C goes to the Earth ground of the DC source.
