SPECIFICATIONS AND BUFFER OPTIONS
DX/256x256 SERIES MATRIX
DX/256x256 Mainframe Rear View with IEEE488, RS232 and LAN Control
Shown with RS422 and RS232 Buffer Modules
INPUT and OUTPUT BUFFERS
Optional Input and/or output buffer modules convert the system to
RS422 and/or RS232 levels. Each buffer module has sixty-four
(64) channels so a fully buffered 256x256 system has four input
buffers and four output buffers. When these modules are used, the
specifications of the system are determined by the input and/ or
output buffers present.
The RS422 input and output buffer modules have two options for
connectors, 68 pin male header or 78 pin female "D" connector.
RS422 Input Buffer Characteristic:
Common Mode Input Voltage (Vcm) -7V<Vcm<+7V
Differential Voltage Swing 200 mV Min
Input Resistance 6.8 KOhm Typical
Data Rate 20 Mb/s Max
DX-256-2
The DX Series is intended to switch almost any digital stream data
stream in a non blocking (any input to any output without disturbing
previously set paths), full fan out (any one input to any or all out-
puts) configurations. The Basic system is intended to switch TTL or
CMOS signal levels.
When used without buffer modules, the system conforms to all TTL/
LVTTL specifications below
