2. UNIT OVERVIEW
The 86447 LS DATA unit provides up to four 9.6 kb/s full-duplex asynchronous
data ports along with four end-to-end RS232 control signals over a single 64 kb
channel. Data transmission is transparent, irregardless of baud rate, start, stop,
or data bits.
The 86447 LS DATA unit can be configured with one, two or four active data
ports with maximum baud rates of 38.4 kb/s, 19.2 kb/s and 9.6 kb/s respectively.
All ports will accept sub-multiple rates of the programmed maximum baud rate.
Front panel LEDs provide monitoring of transmit and receive data activity for all
four available ports.
The unit occupies one shelf slot in an 86430 shelf and requires one channel
assignment of the 24 available channels in a JMUX VT.

3. FRONT PANEL FEATURES
Led Indications
Alarm (red)
Denotes when the unit has lost either Shelf Framing, Data
Framing or operates at an out of temperature range. Shelf
Framing refers to the 2 kHz shelf SYNC clock and must first
be established before a Data Framing alarm can occur. After
shelf SYNC has been detected, the local and remote units
exchange messages to establish Data Framing. Shelf
Framing alarms usually occur if there are no JIF or JMUX
units present.
Xmt and Rcv (green)
These leds are green (steady) if the ports have been
configured but no data activity is present on the transmit or
receive terminals. These leds are green (blinking) if data
transitions are occurring on the transmit and receive
terminals.
Note: All led indications are controlled by the micro-
processor.
Push-button (ACK)
The main use is a led and micro-processor test; pressing the button causes all
the leds to light.
The second use is to put the micro-processor into a "Forth Loop" state. In this
condition, the micro ignores all settings until the JCI software is run. The JCI will
automatically clear the Channel Assignment setting (--) at which point the user
can configure the unit to the desired settings. If the unit is inserted with the ACK
button pressed and then removed and inserted normally (no JCI), all previous
settings will return.
Craft Interface (C.I.) Jack
This is a serial RS232 9600 b/s port for connection to a 386 or better PC. The
supplied JCI software enables the user to configure the unit and monitor the
units status.

4. UNIT DESCRIPTION
The 86447 LS DATA unit can be configured with up to four data ports however,
the following description is for circuit one only. Signal paths for circuits two,
three, and four will be identical as circuit one except for designations, locations,
etc.
All user connections are made to the 86447-90 Interconnect Paddle Board. Four
terminal blocks provide transmit data, receive data, signal ground, transmit
control and receive control interfaces for all four circuits. All pinout arrangements
are provided in the Installation Section of the manual.
A simplified Block Diagram has been included at the end of this section and can
be used for reference for the following signal paths analysis, however the user
should refer to schematics EAS-86447-M1 for complete circuit descriptions.
Transmit Signal Path
The XMT DATA IN bits are received on Paddle Board TB1(1) and sent to the
back connector J1(C1) of the main assembly board 087-86447-01. Plug P4(1)
routes the signal to the RS-232 Interface Assembly Board 087-86447-02 via
J4(1).
U4 on the Interface Assembly Board provides the electrical interface to the
Paddle Board and the necessary level translation and protection from the various
interfaces for the Programmable Logic Gate Array (U2). J2(15) passes the
signal back to the main assembly board on P2(15) to the capacitor chip array
CN3(12) which provides EMI filtering and suppression for U2.
U2(5) accepts the signal where it is processed and routed through various gate
arrays in the chip.
The signal is outputted on U2(78) to the output driver U8. The JVT Interface
J1(C14, A14) consists of a balanced 50 ohm RS-422 signal pair designed for
multi-point transmission.
The unit receives its clock source from the JVT Bus J1(C15, A15) through the
input driver U6. The JVT serial bus operates at 2.592 MHz.

GE Power Management 2001
Receive Signal Path
The receive data bits are received by the input driver U7 from the JVT Bus
J1(C16, A16) and sent to U2(77).
U2 processes the signal and routes it through various gate arrays on the chip.
U2(4) outputs the signal to the capacitor chip array CN3(7), and passes the
signal from (11) to Plug P2(16). The signal is then sent to the Interface
Assembly Board on J2(16) to U4(11). U4 provides the electrical interface for the
Paddle Board. The signal is sent back to the main assembly board via J4(4);
P4(4); and terminated on the Paddle Board TB1(2) as RCV DATA OUT.
Control Signals
Each port is accompanied by RS-232 transmit and receive control signals with a
maximum bandwidth of 300 bits/s. The primary function of the control signals
are to provide an uncommitted virtual wire between two LS DATA units. The
state of the receive control signal is determined by the following configuration
options:
1) End - To - End: The state asserted on the transmit signal is reflected
at the receive end of the corresponding control
signal.
2) Loop back: The receive control signal reflects the state of the
local transmit control signal.
3) Set High: The receive control signal is set to a logic '1'; MARK
condition.
4) Set Low: The receive control signal is set to a logic '0'; SPACE
condition.
XMT and RCV CONTROL signals are terminated on the Paddle Board TB1(4,5)
where they are sent to U2 in exactly the same manner as the data information.

sub-multiple rates of the programmed maximum baud rate.
NOTE: This unit is asynchronous only.
Monitors
DATA - SEND/RECEIVE
Shows current status of all four ports. May be IDLE or ACTIVE.
IDLE status is displayed on the unit's face plate by a steady green
LED while ACTIVE status is denoted by a flashing green LED.
Each port is indicated on the unit by two LEDs. Left side is
transmit, right side is receive and ports count from top to bottom.
The unit's LEDs will illuminate for the number of ports that are
currently configured.
CONTROL - SEND/RECEIVE
May be either HIGH (mark) or LOW (space). The status of the
control lines is determined by the user's drop equipment, however,
the receive control lines may be forced HIGH or LOW by editing the
RECEIVE CONTROL MODE on the JCI screen.
