Introduction
This manual will take you through how to set up the iPad with an RL256 Series unit to allow
the remote control of the RL256 Series unit and audio monitoring via the iPad app of the
RL256 Series unit.
Check RL256 Series unit is up to date.
Make sure that all populated network ports and the Control port are connected to an
appropriate network switch.
To set up the RL256 it will initially need to be connected to a DHCP server.
Press the Sys button then the Firmware tab and check the firmware of each fitted port.
Ports which do not have a card fitted will have an X in the box
Versions should be as follows (or later)
• CPU – Version 1.10
• FPGA – Version 1.03
• DSP – Version 1.06
• State Monitor
o Brooklyn II card – Version 3.00
o ZMAN card – Version 1.02
If the version are as listed above or later then please continue to the next step
Earlier versions will need to be updated as per the update procedure
Next press the Control tab to see the screen shown below
Type the IP address shown into a web browser to be taken to the RL256 Series Web
interface.

RL256 Web Interface
On the web interface check that the Running firmware is 1.0.38 or above.
To update the firmware, use the Choose file button and follow the instructions.
The web interface allows you to set up the RL256 control port.

As standard the RL256 control port is set up to use a DHCP server to obtain an IP address.
Please make sure to connect to a DHCP server before trying to change any settings.
The RL256 control port will not self-assign an IP address so without a DHCP server you will
not be able to set up the RL256 control port.
Once the RL256 has an IP address you can find this address by going to the Sys tab, then the
Control Tab on the RL256 LCD
Please note that the RL256 runs a Network dependant system. The Control Port must be
plugged into an active network for the RL256 to function correctly.
Some features will not be active without this connection being present such as in the
control tab shown above both the IP address and the Mask IP Address will report as 0.0.0.0
regardless of DHCP or Static IP mode.

Setting DHCP or Fixed IP address (LAN only)
The Web interface will allow you to change the control port settings.
You can select whether the unit is in DHCP mode or Fixed IP mode.
Tick the DHCP box to use this mode.
Alternatively, if a fixed IP address is required for use in a system without a DHCP server then
fill out the five boxes.
1. IP Address – type the required IP address.
2. Subnet – type the required subnet mask.
3. Gateway – type the IP address of the gateway.
4. DNS1 – type the address of
a. the required DNS1 server
b. or 0.0.0.0 if no DNS1 is required.
5. DNS2 – type the address of
a. The required DNS2 server
b. Or 0.0.0.0 if no DNS2 is required.
6. Once all five boxes have a valid value the Submit button will appear
7. Press the Submit button to set these values.
8. If the unit has had a fixed IP set and it can’t be accessed on the current network go
to the RL256 LCD and press Sys, then Control and press the Restore Defaults button
to return the unit to DHCP mode.

iPad connection to the RL256
Internal Wi-Fi
To connect the iPad to the RL256 via the internal Wi-Fi adaptor select the Primary Network
to be Wi-Fi from the Default Network drop-down menu.
Next in Wi-Fi Configuration select the required SSID from the SSID drop-down menu.
There is a choice of up to ten different names if multiple RL256 units are being used in the
same area.
Once you have selected the SSID and the unit has had a couple of minutes to reboot the Wi-
Fi interface you will need to change the setting on the iPad
Please note: the only user setting for the Wi-Fi adaptor inside the RL256 is the SSID name.
There is no need to set DHCP/Static IP etc

Go to the Wi-Fi tab and select the SSID that you have set in the RL256.
You will be asked to input a password which will be “m1ndth3g4p” without the quotation
marks.
Please Note: That iPads will default to the last known good Wi-Fi connection when the
RL256 is powered off and the RL256 SSID will need to be reselected on power up.
Next go to the Nixer RL settings on the iPad
Make sure that Location is set to Always – not doing this will cause the App to crash as this
is needed for the Wi-Fi to work correctly.
Also make sure that Control IP box is blank – delete any IP address set in this box as it will
cause the App to not function correctly.
You will now be able to start the App and control the RL256.

Using the LAN (control port) via an external Wi-Fi access point
To connect the iPad to the RL256 via the LAN (control port) and external Wi-Fi access point
select the Primary Network to be LAN from the Default Network drop-down menu.
When selected to LAN the SSID is ignored so doesn’t need to be set.
Next connect your iPad to the external Wi-Fi access (see the instructions for the external
Wi-Fi access point for more details)
Open the iPad Nixer RL settings.

Make sure that Location is set to Always – not doing this will cause the App to crash as this
is needed for the Wi-Fi to work correctly.
Add the IP address of the LAN control port into the Control IP box.
You will now be able to start the App and control the RL256.

Mix and Listen Modes
The iPad App allows the RL256 Series unit to be used in two different ways.
• Mix – in this mode a mix of the channel signals can be created with level control and
pan control
• Listen – this mode operates in one of two ways:
o Hold – Off.
§ touching a channel cell will highlight that cell in green and
automatically route the audio.
§ Stereo channels will be selected in stereo to the left and right output.
§ Mono channels will be selected and sent in mono to the left right
output.
§ Pressing another cell automatically clears the first.
o Hold - On
§ touching a channel cell will highlight that cell in green and
automatically route the audio.
§ Each additional cell touched will also be highlighted in green and the
audio added into the mix.
§ Stereo channels will be selected in stereo to the left and right output.
§ Mono channels will be selected and sent in mono to the left right
output.
§ To clear the selection(s) press the Clear button.
