Unicast Transmission
The unicast transmission will be suitable for the following system.
•When it is necessary to monitor pictures from a specific camera on a specific monitor
System Example
When using the unicast transmission, the number of cameras and monitors should be same. The unicast transmission
is useful in preventing from heavy traffic in the network, not only for this system but also the other systems.
For the unicast transmission, perform the settings of "DESTINATION IP ADDRESS" and...

23
Receiving and Sending Serial Data (RS-485)
The encoder receives and sends serial data (duplex) as shown in the illustration below.
Required Settings for RS-485
Perform the following settings to receive and send serial data.
•Enter the desired size of the packet to be sent in the "WAITING DATA SIZE TO SEND PACKET (1 - 1024 byte)"
input box on the RS-485 DATA PORT page.
The packet will be sent when its size reaches the entered size.
•Enter the desired waiting time to send in the "WAITING...

Rack Mounting
The encoder and the decoder can be installed in the following
racks.
•Racks equivalent to EIA standard: Type 19" EIA standard
(depth: more than 450 mm (17-11/16"))
Important
•Do not install the encoder and the decoder above an appliance which generates heat such a power amplifier. When
installing the encoder and the decoder below a heat-generating appliance, install them below the appliance with a
space equivalent to about 1 unit separating them.
•Keep the temperature in the rack...

29
Mounting the encoder
1. Remove the four rubber feet by removing the four
screws from the bottom of the encoder.
2. Place the rack mounting brackets (sold separately,
see below for details) on both sides of the encoder
and tighten with the four screws supplied to the rack
mounting brackets.
When installing an encoder: WQ-LMK44/1-S
•Rack mounting brackets (Large) x1
•Rack mounting brackets (Small) x1
•Fixing screws for the rack mounting brackets
(M3x8) x6
•Fixing tapping screws for rack mounting...

Installing in a container box (Only for the Encoder)
The encoder can be installed in a container box.
When required to install the encoder in a container box, install as below.
How to install
1. Place the supplied simple mounting brackets with the
supplied fixing screws on the bottom of the encoder.
2. Fix the encoder in the container box by fixing the attached
simple mounting brackets to the box with fixing screws.
(Procure fixing screws locally to fix the encoder in the
container box according to...
