Spectracom SecureSync - Programmable Square Wave out [1204-17]

The Web UI list entry for this card is named: Prog Freq Out, Sine [or: TTL, or: RS-485, respect-
ively].
The connector numbers are: J1…J4 [J1 for the RS-485 model].
Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10MHz out-
puts start at1, because of the built-in outputs).
The Status window displays the following settings:
Signature Control: Controls when the output will be present. See also: "Signature Con-
trol" on page141.
Frequency: Indicates the configured frequency.
Phase: Displays the configured phase offset (e.g., to account for delays caused by dif-
ferent cable lengths, or other latencies).
Lock: Shows, if the output frequency is locked to the SecureSync system-disciplined oscil-
lator.
Note: Even if an output frequency status is LOCKED, it will not be available at the
output port, if the Signature Control for that port has been DISABLED.
