2.5 Connections
Margay has four groups of connectors. All inputs are paired with loop-thru outputs (except RS232 In).
The inputs are toward the rear of the Margay.
Analog and digital connectors
Two analog connectors and one digital (DVI) con-
nector have their separate loop-thru outputs. The
Analog outputs (buffered) always carry the corre-
sponding analog input picture.
The digital output is different. The digital output
carries a digitized version of the selected input. If you
change the active input in the Picture menu, the digi-
tal output changes.
• See 2.5.1 “Connections, Analog & Digital
Sources” on page 22.
Video connectors
Video connections are optional. The Video Input
Module (VIM) is not installed at the factory; it is
installed in the field by the installer. When installed,
the VIM accepts composite, S-video and component
video (YPbPr). Each input connector is paired with its
separate loop-thru output.
• See 2.5.2 “Connections, Video Sources” on
page 24.
Control connectors
You can control the Margay with a remote control
or with serial commands from a computer or other
device. Send commands in either the RS232 or
RS485 standard.
Normally, you send RS232 commands to one Mar-
gay’s RS232 In and loop out the RS485 Out to the
next cube’s RS485 In.
RS485 has better long-distance communication.
• See 2.5.4 “Connections, Control: RS232 &
RS485” on page 28.
Power
AC power (115V or 230V) can be looped thru to
neighboring cubes. The limit on loop-thru is
• 4 Margays when using 115V;
• 8 Margays when using 230V.
The power supply is auto-ranging.
• 8 cubes when using 230V.
• See 2.5.3 “Connections, Power” on page 26.
