3.2 General Operation
3.2.1 Front Panel Functions
The front panel can be used for the following purposes:
•View current input/output routings (ties) on LCD
•Make new ties either starting from input or from output
•Recall or Save Preset patterns
•Lock or Unlock the front panel
•Change EDID configuration
•View EDID configuration and preset configuration on LCD
•Monitor & Control Power On/Off status
All of the front panel buttons have built-in LEDs to help with their operation.
Front panel functions are designed for maximum intuitiveness. With just a little
practice, one can easily learn to monitor and control the matrix.
LOCK is used to disable all the keys on front panel. Lock the front panel by
pressing LOCK button. Hold the same button for 3 seconds to unlock the panel.
Locking the front panel is intended to prevent inadvertent actions for example,
if the buttons are pressed unintentionally. Note that when the front panel is
locked, the IR remote function is also locked, but other means to control the
matrix (RS-232 and IP) are still functional.

The front panel pushbuttons have LEDs built-in. The buttons can be off, on, or
blinking. These modes help users control the matrix with ease.
Front panel button LED states
3.2.3 Reading the LCD routing configuration
Easy to understand routing information is displayed on the LCD. On the LCD the
input row changes but the output positions are fixed and never change.
In the above example, the routing configuration can be understood from the
output end as follows:
Output 1 is tied to Input 1
Output 2 is tied to input 1 and so on ...
3.2.4 Turning the unit on and off
Press the power button any time to turn ON the matrix. For safe operation, to
turn the unit OFF, you must hold the power button for 3 seconds.
3.2.5 Making AV Routing or "Ties" from the Front Panel
Hall Research products are designed with maximum usability in mind. That’s
why the front panel allows users to initiate “ties” either from the OUTPUT point
of view or from the INPUT.
For most users it is more logical to initiate ties starting with the OUTPUT. Think
of it as: “I want OUTPUT 1 to get its video from INPUT 2” for example!

3.2.6 Making a tie starting from the OUTPUT
To tie an output to an input, perform the following steps:
1. Press the desired output button. The button for the currently tied input
will light up. Note: At this point, you can use the navigation (
▲▼ ) buttons to
view the previous or next Output routing.
2. Press the input button you want to tie to. This will make the selected
input button blink. Blinking button designates it as a “candidate”
choice; an actual tie is not made until you press the SET button.
3. Press the SET button. If you do not press the SET button, after a few
seconds, the process times out and button lights go out.
Example:Route output 1 to input 2
3.2.7 Making a tie starting from input
Routing from the input end is similar to the above but an input can be routed to
multiple outputs.
1. Press one of the input buttons. That button will light up in solid along with
ALL the outputs currently routed from that input. Note: you can use the
navigation ( ▲▼ ) buttons to view the previous or next Input routing.
2. Select all the outputs you wish to route to. Candidate outputs can be
multiple and all will be blinking until the SET button is pressed. To remove
a candidate, press the blinking output again.
3. Press SET to apply the changes.
Example: Route Input 1 to Output 1, 2 and 3

3.2.8 Blanking Outputs
The matrix allows the output to be blanked. You can blank a particular output or
you can blank all the outputs that are connected to a specific input.
1. To blank an output, hold the Output button for 3 seconds or until its led
starts blinking.
2. Press SET to apply the change. The blanked Output will be crossed on the
front panel LCD with an “X”, indicating that it is blanked.
Example: Blanking output 1
You can also blank all the outputs that are connected to a particular input.
1. Hold the input for 3 seconds.
2. Press SET to apply the change. All the affected output ports and blanked
3.3 Presets (Memorized Routing Patterns)
The number of presets accessible from the front panel is the same as the total #
of input buttons. Each front panel input button can memorize a pattern.
Therefore, you can recall 8 presets.
3.3.1 Saving ongoing configuration as a Preset
1. To save ongoing configuration as a preset, hold PRE button for 3 seconds
until it blinks.
2. Select preset position by pressing an input button
3. Press SET to save the pattern as a Preset in that key position.
Example: Saving ongoing configuration as Preset #1

3.3.2 Recalling Presets
1. To recall a saved preset, press the PRE button.
2. Select the desired Preset # by pressing an input button.
3. Press SET to recall the preset.
Example: Saving preset #1 from the previous example
3.3.3 Editing or Copying Presets
1. To edit a saved preset, press PRE button.
2. Hold the preset number you want to edit on the input button until you see
the prompt "Editing Preset #" on LCD.
3. Start changing the preset config from the output end just like making ties
from the output end. Holding an entry will clear the output. Unassigned
outputs will be blanked by default.
4. Press SET and select the preset number you want to copy. Note that you can
even copy the preset to the number you started editing.
5. Press SET again the save the new preset.
Example: Edit output 1 in Preset #1, which is saved in previous example and
saving it to preset #2

3.4 Using the IR Remote to route video
The IR Remote included with the Matrix allows simple control
of the matrix. You can use the IR remote to power the matrix
on/off and you can use it to make video ties.
Similar to making ties from the front panel starting with the
Output channel, press one of the 8 output buttons on the IR
Remote, then press the input you want it to show. You can also
tie all the outputs to the same input quickly by pressing the ALL
button in the output group, then press the input you want all
outputs to show.

4.0 EDID management
The HSM-88-4K gives users the flexibility to configure the EDID for each input.
The source for the EDID data associated with each input can be from one of 15
standard built-in choices or copied from any of the TVs connected to a
particular output. There is also an advanced mode for dynamic “on-the-fly”
EDID Computation to guarantee that all displays connected to any input will be
able to display the video from that input (as explained below in Section 4.2).
By default, the EDID for all inputs are set to 1080p video with 2-channel audio
for maximum compatibility but users can easily change the EDID used at all or
any of the inputs.
4.1 EDID Configuration
This option allows the user to choose a specific EDID table and load it into any
selected input port on the matrix. HSM-88-4K comes with 15 common EDIDs
saved in its internal memory or you can copy the EDID of any TV connected to
outputs.
Press MENU and navigate to "EDID Config" and press SET.
Browse through the 15-different preset EDIDs or any of the eight EDIDs
of the current outputs.
Press SET to select the EDID.
Select an input to copy the EDID.
Press SET to load the EDID to selected input.
Note: If you decide to copy EDID from an output, but the EDID of the output is not valid (for
example if the output is disconnected), the Matrix does not modify the input EDID and will
display an error message.
Below are the choices of EDIDs under EDID Config menu:

4.2 Compute EDID
When “Compute EDID” mode is selected, the system dynamically generates the
EDID for each input according to the “highest common denominator” of the TVs
that are routed to that input. To select this mode:
Press MENU and navigate to "COMPUTE-EDID" and press SET.
Press SET again to confirm.
When the “Compute-EDID” mode is enabled, routing an input to multiple TVs
with different capabilities will force the system to “compute” a new EDID for
that input based on the TV with minimum resolution capability. Therefore, in
this mode if the EDID changes a short interruption may result in the video signal
from the source as it changes its resolution.
Example: say you have two monitors, one that supports 1080p and one that
supports 4K. When a particular input is routed to both of these outputs, the system
will compute an EDID with 1080p for the input because a 4K signal would not be
displayable on the 1080p monitor. Now let’s assume the user disconnects or
switches the 1080p monitor to a different input. Then, the only monitor routed to
our source is the 4K one. The system will notice this and re-compute a 4K EDID for
our input causing the source to output 4K video (if it can). Switching takes a
couple of seconds. If the 1080p monitor is turned back on or routed to the same
input, the system will downgrade the EDID for the source to 1080p.

5.0 Network Settings
As shipped from the factory (or after restoring factory defaults), the HSM-88-4K
IP address is set for static IP address of 192.168.1.1. To change the IP or to
switch to DHCP, you can use either RS-232 or Telnet.
For example, to use the RS-232 port to change the IP address do the following:
•Connect a PC with Terminal-Emulator software to the RS-232 port
•DHCPn command can be used to change DHCP setting
•Please see the next section with further information on commands
6.0 Serial & Telnet Commands
Telnet port is 6324, RS-232 port settings are:
Baud rate: 115200, Parity: None, Stop: 1-bit
•Commands are in ASCII format.
•Commands are case sensitive.
•Use a single <CR> character to terminate each command.
•Responses from the Matrix are terminated with <CR><LF>.
•Other than Power command (PW1), the matrix must be powered on.
•Unknown commands respond with “INVALID COMMAND”<CR><LF>.
•After plugging power to the matrix, you must wait ~45 seconds for it to fully
boot up before sending any commands.
•Command characters should be sent continuously without pauses. If you
pause for more than 5 seconds, the command will not execute.
•When the front panel buttons are used, some serial commands will be sent
out the RS-232 port.
