Congratulations to the purchase of Digital8 Expander and welcome to the world of manikk!
manikk Otto Digital8 is an optional expander module for use together with some other manikk modules. It has pins on the backside with a SPI interface for communication with the master module that it expands. The 8 jacks gives 8 digital outputs.
The active expander gives additional features and outputs to the master module.
Read the manual for the master module carefully, to see if that module supports the expander or not. Some master modules may have support for two or more expanders as well.
The Digital8 Expander has the numbers 1 to 8 printed for the 8 jacks on the frontpanel.
See here how to attach stickers to the front.
See here how to connect the active expander to the master module.
See also the ADSR Expander module. The ADSR Expander is a nearly identical digital expander with 8 jacks, but it has a frontpanel designed for the ADSR Expander functions.

Front panel layout
The Digital8 Expander is an optional expander module that expandes the functionality of some of the other manikk modules.
The module that controls the Digital8 Expander is here called the master module.
It gives 8 additional digital outputs.
The function and meaning for each digital output jack depends on the master module. Read the manual for the master module for details.
The module has a SPI interface and needs to be connected to the master module by female-to-female dupont cables.
Power and GND are also taken from the host/master module by two dupont cables.
This module should therefore not be connected to the Eurorack power supply by itself.
The frontpanel has the number 1 to 8 printed for the jacks.
Multiple Digital8 expanders can be cascade connected if the master module supports this.
Two or more active expanders can be cascaded.
The master module feeds data to the module to the MOSI in pin.
When chaining or cascading modules you need to connect the MOSI cascade out to the MOSI in on the next Digital8 Expander down the chain.
All the other signals, GND, +5V, SS, MISO and SCK should be connected in parallell for all the expanders. Only the MOSI in and MOSI cascade out are connected in serial chain.
Read the manual for the master module to see how many Digital8 Expanders it can support. Normally only one.
Pin mapping on the backside
There are two versions of the digital expander
The first version
The first version has its components directly soldered on the Otto.
The first version of the Digital8 Expander has a single line pinstrip with 6 pins at the bottom of the module. The 6 pins continued directly below the 32 pins on the Otto.
This version was mainly created for use when only one expander was supported.
If you want to cascade/chain multiple modules in series with this version, you have to create your own special cables.

The second version
The second version is designed as an addon to the Otto Passive Mono.
It also has a dual row pinstrip, which makes it very simple to use when cascading/chaining multiple modules. You only need to use the provided female-to-female dupont cables and connect the next expander down the chain. Input on the pins in row 1 and chaining/output from the pins in row 2. Connect MOSI cascade out to MOSI in on the next module.

If you have purchased a module, you need to install it in your eurorack case. Use the supplied screws to mount it in your rack.
An expander or add-on needs to be attached to the back of a master module via pin-strips. Either directly or via dupont-cables.
There are three types of power requirements for manikk products:
- Completely passive products requires no power.
- Normal eurorack modules requires +12V and -12V from your eurorack system. Connect with IDE ribbon cable.
- Some kits and add-ons requires only +5V from a master module. Connect directly or with dupont-cables.
- Make sure to use approved and good power supply in your system.
- Always turn off the power to your system when installing or uninstalling modules.
- Make sure to get the polarization correct when connecting cables.
- When you connect an IDE flat ribbon cable to the eurorack power distribution, the negative -12V is normally indicated with text on the PCB and with a red stripe on the cable.
