Universal Time
Code (UTC)
Port
The Universal Time Code (UTC) port located on the back panel provides a
connection to a satellite time-code receiver, or equivalent.
• The DB-9-F UTC port can be selected for receive-only RS-232 or RS-422
interface, using SGConfig.
• Supported UTC Port protocols are IRIG-B and Rugby
• Communication parameters are determined by the protocol application.
Note
Many IRIG-B receivers are available with modulated and/or unmodulated
output options.
• IRIG-B is received on CTS port.
• The input to the UTC port must be unmodulated.
• If the unmodulated output of the receiver is a coaxial connection, a converter
will be required to interface the D25.
