AES Switcher Sentinel

2+1 Installation and Operation Manual
INSTALLATION
Remote Control Connections
The AES Switcher Sentinel 2+1® has three SPST Normally Open (NO) relay con-
tact closure remote control outputs located on the top 6-position pluggable screw ter-
minal block (TB2 top). When a relay is active it will make connection between its
NO contact and its common (CM). All three relay commons are isolated from one-
another. The relay outputs can be configured to close on input silence, AES error, or
switch position (activity). The operation of K4, K5, and K6 is determined by the
configuration assigned on the “I/O Setup” page.

(Bottom Row, TB2)
The AES Switcher Sentinel 2+1® has five remote control inputs labelled “CH1”
“CH2” “CH3” “RMT4” and “RMT5” located on the first five pins of the bottom 6-
postion pluggable screw terminal blocks (TB2 bottom).
CH1 =
Momentary closure to ground switches Input 1 to the Output.
CH2 =
Momentary closure to ground switches Input 2 to the Output.
CH3 =
Momentary closure to ground switches Input 3 to the Output.
RMT4 =
EXTernal sustained trigger or Auto/Manual toggle mode.
Closure to ground triggers.
RMT5 =
Analog Out /Headphone Monitor Audio Toggle. Closure to
ground triggers.
RMT4 Input Modes: Auto/Manual Toggle: Pulsing the RMT4 input toggles unit
between Auto and Manual switching mode.
EXTernal Sustained: Holding the RMT4 input low switches the unit to the backup
input, releasing returns to the primary input.
The terminals blocks accommodate wire sizes from 16 - 28 AWG solid or stranded.
Before installing a wire, remove the euro-block screw terminal plug and turn each
capture screw fully counterclockwise. Strip each conductor to a length of 0.25” and
insert the conductor fully into the terminal. Turn the capture screw fully clockwise
to secure the conductor. Verify that no bare wires are exposed.
LAN / NET Jack
RJ45 Ethernet jack for 10/100baseT LAN/WAN connection.
Chassis Ground (Chs Gnd)
#4-40 screw for connection to the station/site ground system.
