UniCMT board top

Description of the UniCMT board top

Cassette recorder connector
It is used to connect the UniCMT to the computer. The cable must be plugged in straight, not twisted when the UniCMT is in the computer and the USB flash drive is facing the user. Please look carefully at the pictures.

CAUTION

Before installing the UniCMT in place of the built-in cassette recorder, read these instructions carefully and make sure the computer is turned off and unplugged from the power. Please, pay special attention to the connecting cable. Twisting the cable or wiring it incorrectly (e.g. moving it one pin too far) can damage the UniCMT and the computer!!!

Battery holder
CR1220 battery holder (battery not included). The battery is only used to maintain the internal clock, which is used to set the file time when saving files. If the correct time when saving files is not important to you, it is not necessary to install the battery. The accuracy of the internal clock is not high, the error can be a few seconds per day, please adjust it regularly.

USB flash drive connector
Format the USB flash drive up to 32 GB to the FAT32 file system. The file manager is stored in the internal memory of the UniCMT and can be loaded even without the USB flash drive inserted. All other programs and data must be stored on the USB flash. There may also be run.cfg file in the /unicmt folder on the disk with a configuration for automatically loading or running certain data types.

1st (left) LED
The left LED indicates the status of the USB flash drive:

  • red – USB flash drive is not inserted or does not have a FAT32 file system
  • green – USB flash drive with a recognized file system is inserted

2nd (right) LED
The right LED indicates the status of the cassette recorder emulation:

  • not lit – nothing is happening, no more data, the manager will be loaded
  • green – there are more data (multi file MZT), the engine signal starts playing
  • red – playback finished, nothing is sent until the motor signal
  • flashing orange – loading from emulated cassette recorder
  • flashing red – saving to emulated cassette recorder

Grey (left) button
It has no function in the current firmware and is only used for updating it, see below in the section Firmware update.

Red (right) button
It has no function in the current firmware except reset after firmware update. When SW1 is ON, it is used to reset the internal MPU. This can be used in case you want to e.g. exclude files from the playback queue and do not want to reset the whole computer.

Popis spodní části desky UniCMT

DIP switch It is used to preset some hardware functions. In the current firmware only SW4 is relevant, or SW1 can be used (hardware connected).

  • SW1 – in the ON position the red button is connected to reset the MPU
  • SW2 – it has no function in the current firmware
  • SW3 – it has no function in the current firmware
  • SW4 – in ON position the manager boot is adapted for MZ-700

SW4 setting to ON is necessary for MZ-700 EN and JP computers
the name when loading the manager contains unreadable characters
this is fine, it's machine code to speed up the loading process
