The multiplexer is full duplex. The
“
full duplex
”
means to record multiple cameras and playback synchronously.
6.1 RECORD
The multiplexer can support general VCR or time-lapse VCR recorder.
(a) TO RECORD USING EXTERNAL TRIGGER SIGNAL FROM TIME-LAPSE VCR：
The time-lapse VCR recorder generates a trigger signal from
“
VCR trigger
”
to signal multiplexers when it is the time to switch
channels.
We recommend using this feature when user
’
s VCR recorder supports this feature.
Using this feature the record time must be set to
“
SYNC
”
and interconnect VCR and ARC-19516.
The acceptable trigger signal is a falling edge (negative) trigger.
(b ) RECORD BY SETTING RECORDING TIME：
The multiplexer can calculate channel-switching time by setting recording time at menu set up.
The recording time of the multiplexer must match the recording time set on the VCR recorder. If general VCR are been used,
the recording time must be set to 2H and the user can choose from FILED or FRAME as recording type.
The multiplexer supports: SYNC, 2 hours (2H), 12 hours (12H), 24 hours (24H), 24 hours real-time (24RH), 48 hours (48H), 72
hours (72H), 120 hours (120H), 168 hours (168H), 240 hours (240H), 480 hours (480H), 720 hours (720H), 960 hours (960H)).
6.2 PLAYBACK
Because the playback path (VCR input path) and channel 16 uses the same path, therefore channel 16 will not be recorded while
using playback function.
