Page 9 of 28
Switches mains input to Paragon-X on or off.
12. 1PPS Reference Input
Typically, sourced from an external GPS receiver (e.g. Paragon-X option 132). Alternative to 1PPS
input on connector 17. Single-ended 75Ω BNC connector.
13. Wander Measurement Inputs
Accept T1, E1 (75Ω unbalanced or 100Ω balanced) and 2.048MHz inputs. In external wander
generation mode, accepts T1, E1, 2.048MHz and 10MHz wander-modulated signals from an external
source.
Input signal amplitude range: 1V–3V peak to peak into 50Ω.
14. Reference Inputs
For connection to T1, E1, 2.048MHz or 10MHz clock reference signals.
Clock input amplitude range: 0.6V-3V peak to peak.
See also connectors 16 and 17 below.
15. Reset Switch
Resets Paragon-X to its power-on condition and resets IP address to factory default 192.168.3.100
16. 64K AMI Reference Input
For connection to 64kb/s external system reference clock.
Pin 2 = tip (+), pin 6 = ring (-), pin 1 = GND.
17. GPS Reference
An alternative to connector 12, accepts a 1PPS reference input signal on pin 9 (pin 5 GND).
Accepts Time of Day (ToD) message input as RS-232 on pin 2 (pin 5 GND) and can generate ToD
message output as RS-232 on pin 3 (pin 5 GND). Paragon-X can display ToD messages directly as
received, or qualified by 1PPS signal.
18. GPS Antenna Input
Not used.
