Connecting a Computer

The following two methods are available for connecting the
DTXPRESS to a computer.
1. Directly connect the computer’s serial port to the
DTXPRESS’ TO HOST jack.
2. Connect the DTXPRESS’ MIDI IN jack to the computer
through a MIDI interface.

1. Directly connect the serial port to the TO

HOST jack.

The method used for connect and transferring signals between a
computer and the DTXPRESS is basically the same, no matter
what type of computer is used.
Getting More Out of Your DTXPRESS
Use a cable to connect the devices and set the HOST SE-
LECT SWITCH according to the type of computer serial
port and clock used. Carefully read the instructions on
the right side of this page and select an appropriate cable
for the type of computer you are using.
HINT
The input signal from the TO HOST jack will be trans-
mitted to the DTXPRESS’ tone generator and se-
quencer, and simultaneously transmitted to the
DTXPRESS’ MIDI OUT jack. At this time, only mes-
sage for the port number that is set in the Utility mode’s
[2-10. Host Thru Port] (P. 56) will be sent to the MIDI
OUT jack.
The signal from the tone generator and sequencer is
merged with the signal from the MIDI IN jack and
output to the TO HOST jack.

2. Connect the MIDI IN Jack to a MIDI Interface

If you are using a computer equipped with a MIDI interface,
connect the MIDI OUT jack on the computer to the MIDI IN
jack on the DTXPRESS. Set the HOST SELECT switch to the
“MIDI” position.
If you are using a Macintosh series computer with an external
MIDI interface, connect the MIDI interface to the computers
RS-422 jack (modem or printer port), connect the MIDI OUT
jack on the interface to the MIDI IN jack on the DTXPRESS.
Set the HOST SELECT switch to the “MIDI’ position.
*When the HOST SELECT switch is set to the “MIDI” position,
the transmission and reception via the TO HOST jack is ig-
nored.
