MODEL 1583-10 Data Distribution Amplifier
1.0 Equipment Description*
The 1583-10 Data Distribution Amplifier is a dual-functionality unit which may be configured in either of
two (2) modes:
• 1:8 Mode, 1:8 data distribution plus pass-through mode; provides one (1) data input (J1)
with eight (8) data outputs (J4 - J11) and a Input ‘pass-through’ (J2) for input data to be sent to another
device OR ....
• Dual 1:4 Mode; two (2) data inputs (J1 & J2), each with four (4) data outputs
(J4 - J7 and J8 - J11 respectively).
All data ports are (user selectable) RS422/423 (RS232 compatible) DB9, female connectors. Data signals on
the DB9 connectors are pin 2 (RS232/423) or pins 2 & 7 (RS422). The Data activity monitor is (factory) set
from 1 to 9 minutes.
Dual switching power supplies provide redundant power. Front panel LEDs indicate power supply operation,
1:8 or Dual 1:4 mode, Data activity (Inputs A and B), and selected interface (RS422 or RS423). The unit is
housed in a 1.75” rack mount chassis. Rear panel provides Alarm Interface (DB25) and Data type selection
(RS 422 or 223(RS232 compatible) switches.
