DID Set Up
When the matrix is completely connected and turned on it will load the default EDID, which is the
highest common native resolution of the connected devices. (i.e. In the diagram below the default would
be 1080p with 2ch audio. Multi-channel audio and 3D are not enabled on default mode, unless all devices
support these features.)
4K/UHD-Dolby TrueHD
Input 1
On default, all devices in the diagram will work at 1080p. If a device is not syncing or a different
resolution is required, internal EDID or EDID copy and load should resolve these issues. The UHD-
PRO3-1616M can copy and store up to 20 EDIDs to memory.
Step 1: copy an EDID
Before an EDID can be loaded to an input, it must first be copied to the matrix's memory. Each
display's EDID can be saved individually to one of the matrix's twenty preset EDID memories.

Step 2: load a copied EDID to an input
Once EDIDs have been copied to memory they can be loaded to a specific input.
Note: (refer to the diagram above) Using the EDID of output 3 with input 1 will enable 4K/UHD and Dolby TrueHD to
pass. With these settings, output 2 will receive no audio or video and output 1 will receive no audio.

Step 3: Load an internal EDID to an input
If the first two steps don't produce the correct resolution or audio configuration, the fourteen
internal EDIDs should resolve the issue.

RS-232 and TCP/IP commands:
To access different EDIDs through RS-232 or TCP/IP, the following commands must be used.
EDIDMSetX default EDIDMSetX default Sets the EDID of an input to the default EDID
Ex. EDIDMset2 default - sets input 2 to default
EDIDMSetX saveY
EDIDMSetX intZ
EDIDMSetX saveY
EDIDMSetX intZ
Sets the EDID of an input to the previously saved EDID memory
Ex. EDIDMset1 save3 - sets input 1 to EDID memory 3
Sets the EDID of an input to one of the internal EDIDs
Ex. EDIDMset3 int6 - sets input 3 to the internal EDID - 1080p 3D Dolby

Matrix Status
When installing or troubleshooting it's important to verify settings, or be able to come back to a
project and see how it was set up. The AT-UHD-PRO3-1616M matrix settings are viewable through
the front panel display. View current I/O settings, firmware version, IP, MAC Address, and the RS-
232 baud rates of not just the matrix but output zones as well.

LAN
For convenience, the matrix comes with DHCP default on. This ensures the matrix IP will not
override another device.
To find the matrix IP:

Select Input Number
AT-UHD-PRO3-1616M
FW Ver: 0.3.XX
IP Address:
X.X.X.X

EX. 010.010.001.200
The address to type into the
browser would be 10.10.1.200
Browser WebGUI
Atlona has created an easy to use WebGUI for changing settings and controlling the matrix.
To begin, plug a LAN cable into the matrix and your network router, then type the IP address of the
matrix into a web browser (as seen below).
If any stability issues are experienced, disable any anti-virus or firewall that may be
interfering with network communication to the Matrix. Once set up is done and the
matrix GUI is no longer being used, the firewall and anti-virus can be re-enabled.
A login screen will appear (this is the same log in for admin and general users). For the first log in (and future
admin changes) the username is "root" and password is "Atlona".
Note: Admin password can be changed within the WebGUI (see page 16).

RS-232 Connection
RS-232 pin out will be determined by the RS-232 cable
RS-232 is often connected through a DB 9-pin to captive screw
connector. The pins will have functions associated with them,
some will be unassigned.
Note: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5
for ground. On some devices functions of pins 2 and 3 are
reversed.
Set Up
To set up the RS-232 hyperterminal (if not using 3rd party software) use the following steps:
1. Connect the AT-HD-1600-SL to a PC using a DB9 to USB cable
a. Remove the DB9 connector, strip and connect the wires to the included captive screw
connector (as explained above), then connect the captive screw connector to the matrix
2. Go to the Device Manager folder (see picture A)
3. Find the AT-HD-1600-SL COM port and right click with a mouse and select properties
(see picture B)
NOTE: If unsure which COM port is the AT-HD-1600-SL, unplug the cable and plug it back in. It will
disappear and reappear on the COM port list.
4. Under the properties menu select the port settings tab and update the menu to the AT-HD-1600-SL default
settings of:
CONTROL1:Bits Per Second: 115200, Data Bits: 8, Parity: None, Stop Bits: 1 and Flow Control: None.(see picture C)
CONTROL2:Bits Per Second: 9600 , Data Bits: 8, Parity: None, Stop Bits: 1 and Flow Control: None.
TCP/IP Connection
Login :Username:root Password:Atlona
Default IP: 192.168.5.247:8700
NOTE: TCP/IP Connect matrix LAN ports through management software with AMS
Set up is done and any hyperterminal program may be used to control the AT-HD-1600-SL now.
