Titan CPU Channel Mul plexer - Interface
Interface
REM (Remote):
The REM jack permits the Titan CPU recording func on to be started and
stopped by means of an external switch. This func on is implemented on
an 1/8” Tip-Ring-Sleeve (TRS) jack, which provides connec ons for both an
external switch and an LED to indicate the START/STOP status:
Tip - External Switch
Ring - LED
Sleeve - Ground
The CPU will start recording when a switch closure is made between the Tip
and Sleeve contacts. When the switch is in the open posi on, recording will
stop. If an LED is connected between the Ring and Sleeve contacts, it will be
illuminated when the CPU is recording.
Titan Input Module Ports
The Titan CPU has twelve iden cal Titan Input
Module Port connectors. LEDs integrated into
these connectors indicate when a connected
Titan Input Module is transmi ng and receiving
data. Titan Input Modules connect to these
ports using industry-standard ‘straight-through’
Ethernet cabling, which provides power, sync and
data connec ons on a single cable. The maximum
recommended cable length from the Titan CPU to
a Titan Input Module is 25’.
NOTE:
When the Remote Switch is ON (i.e. recording) the Remote LED will blink
mostly ON. When the Remote Switch is OFF the Remote LED will blink mostly OFF.
The Remote Switch may be connected at any time. If the Remote Switch is ON when
the connection is made, the CPU will begin recording immediately with the current test
con
fi guration.
