Mt-946 Status Led Indicators - AFi MT-946 Instruction Manual

MT-946 STATUS INDICATORS
The MT-946 transmitter provides the following LED status indicators to aid in installation and
troubleshooting:
DATA TX / RX INDICATORS
DATA TX and DATA RX indicators are provided to monitor the data and contact closure channels. TX1
and RX1 correspond with the multi-protocol input/output of data channel 1. TX2 and RX2 correspond
with the input/output of contact closure channel 2.
DATA TX
A green LED indicator is provided to monitor the data/contact closure coming in from the electrical
interface, through the MT-946, and out onto the fiber. The intensity of this indicator will vary with input
data patterns, however in typical data applications it will cycle on and off as data is transmitted. For
contact closure applications, this LED will be on solid when the CONTACT IN terminals are connected
together. Data/contact closure transmitted status associated with this LED is summarized below.
DATA TX LED
Green
Off
DATA RX
A green LED indicator is provided to monitor the data/contact closure coming in from the fiber, through
the MT-946, and out onto the electrical interface. The intensity of this indicator will vary with input data
patterns, however in typical data applications it will cycle on and off as data is received. For contact
closure applications, this LED will be on solid when the CONTACT OUT terminals are joined together.
Data/contact closure received status associated with this LED is summarized below.
DATA RX LED

VLI 1 THROUGH VLI 4
A bi-color LED indicator is provided for each of the four video inputs to the MT-946. DC power and
video status associated with each of these LED's are summarized below.

OLI
A bi-color LED indicator monitors the optical input power of the data signal that is being received at the
MT-946 from the MR-946 or the RR-946. DC power and optical input status associated with this LED
are summarized below.
