SPDIF OUT jack
z
This is a digital audio output jack.
Signals can be output in IEC60958-3 (S/PDIF) format.
To link a second SS-R250N, connect the SPDIF IN jack on the
other unit to this jack. (See "Making connections for link play-
back" on page 40.)
RS-232C connector
x
This is a 9-pin D-sub RS-422 control input/output connector.
Connect a TASCAM RC-SS150 remote control or personal
computer, for example, here. (See "Using the RS-232C con-
nector" on page 102.)
PARALLEL connector
c
This is a 25-pin D-sub parallel control input/output connector.
Connect a TASCAM RC-SS20 or other external controller here.
Ethernet connector
v
This is an Ethernet port. Use this to connect to a network,
transfer files and control the unit externally.
OPTION slot
b
Use this slot to install an I/O card (sold separately).
AC IN connector
n
Plug the included power cord in here.
PARALLEL connector overview
The PARALLEL connector on the back allows external control of the unit. (A
TASCAM RC-SS20 can also be connected.)
The pin assignments are as follows.
Pin No.

IN:
External command reception active low (usually 30
msec or more, 1 sec or more when recording MP3 files,
functions when connected to GND)
OUT: Transport status display signals by open collector (10Ω
output impedance, 20V withstand voltage, 35mA max-
imum current)
+5V: 50mA maximum supplied current
*Pin 14 (Remote Select)
When high, the first function is enabled when there are two functions
separated by a / for the input pin in the above table (pins 2–6 and
15–19), and it can be used as an ordinary parallel controller.
When low, those input pins function as flash start keys.
