DESCRI PTION
Asynchronous 16-line single speed multiplexer
and connecting cable to DCOSCS
mounting panel. (Does not include the
DC08CS) Order must specify the Baud
rate (up to 1200 Baud for 16 lines.) If no
speed is specified 110 Baud, will be supplied.
Up 'to 2 DMll-AB plug into one
DC08CS_
Telegraph and Telex line Adapter distribution
panel. Mounts line adapters for
interfacing between the DMll-AB and
telegraph or Telex lines. Accommodates
up to 16 dual solid state telegraph line
adapters, type DC08CM_ (Each DC08CM
provides two Telegraph line interfaces).
Dual solid state telegraph line adapter.
This unit is used with either externally supplied
neutral or polar line power or internally
supplied line power (793 or 793A).
Line Current Adjusting Option. Provides
rheostats on each send and receive lines
for adjusting send and receive line current.
Meter is provided for current monitoring.
Can drive unipolar or bipolar lines
± 45v to ±8Ov and ±80ma. per line
Line Terminator Panel. Provides screw terminal
connection points for interfacing
the DC08CM Telegraph Line Adapters to
telegraph lines. Can accommodate up to
32 lines, with four connections provided
for each .. Cabling allows unipolar or bipolar
operation in groups of 16 lines.
