1 Introduction The LockitModule ACN-LM offers to implement timecode and sync capabilities plus metadata processing based on a modular NVMe form factor plug in card. It features industry standards such as SMPTE 12M, MIDI timecode, ITU/REC tri-level video sync, audio wordclock and multiple pulse per frame camera shutter sync. The module also seamlessly integrates Ambients ACN, an IEEE802.15.4 based, wireless sync and metadata network.

2.2.8 ACN RF Connector “ANT” carries the ACN IEEE802.15.4 RF signal via a standard U.FL socket. If RF output is not disabled permanently with no option of alteration through the user this connection must be properly terminated with a compliant 50 Ohms IPEX lead and suited antenna with max 2dBi in the according range.
