INTRODUCTION The Frequency Stabilizer consists of three
equal Stabilizer Units and a Switch Panel.
Each Frequency Stabilizer converts the Site
powerline frequency to an output of 220V

The Output from the Frequency Stabilizer
is utilized by the Disk Drives.
The nominal load is 4.6A (when starting up
the Disk Drives approx. 14 A).
One Stabilizer Unit is utilized by MMD #
[
One Stabilizer Unit is utilized by MMD #

One Stabilizer Unit is utilized by SMD and
ST.FD. DRIVE.
OH 1 The Switch Panel contains 3 switches (one
OH 2 for each Stabilizer Unit).
Each Switch has 3 positions as follows:
Pos 1: Freq. Stab. Powers the DISK DRIVE
Pos 2: No Power
Pos 3: Site Power is bypassed to the DISK
DRIVE
OH 3 The Front Side contains a Circuit Breaker
(CB1) and two Signal Lamps.
When the Circuit Breaker is positioned in
ON, the input Power Lamp (green) should be
illuminated immediately, and after a three
seconds delay the power is available at the
output and the Fault Lamp should be extinquished.
The Rear Side provides access to Input Power

GENERAL OH 1 The STAT. MUX. is a Communication Device
de-
signed to permit eight Asynchronous Data
Terminals to share a single Communication
Line between Local Site and Remote Site.
The Stat. Mux. connected to the Host Computer
via the TDX SYSTEM is the Master Multiplexer.
The Stat. Mux. connected to Terminals is
the Slave Multiplexer.
The Port connected to Communication Line
is a Composite Interface (configured as DATA
TERMINAL EQUIPMENT) and the Ports connected
to either Computer or Terminals are Channel
Interface (configured as DATA COMMUNICATION
EQUIPMENT).
MUX. Sec. 1.1.
INTERFACING OH 2 Baud Rates for Channel Interface can be set
on switches comprised in the Stat.Mux.
The signals are interfaced as mentioned in
the V24 (or RS-232) recommendations.
MUX Sec. 1.2.3.
CONFIGURATION OH 3 The configuration of Stat.Mux on Local
Site/Remote Site will be as follows:
A Master Multiplexer is connected to the
Host Computer (via the TDX SYSTEM) on local
Site and a Slave Multiplexer connected to
the Terminals on the Remote Site.
Data from the Terminals will be multiplexed
in the Slave Stat. Mux. and transmitted via
a full duplex link to the Master Stat.Mux.
where the data Stream is demultiplexed as
output to Computer Ports.

In this way it looks as if each Terminal
has its own direct connection to the Computer
System.
A Command Port provided on the Multiplexer
allows Message Broadcast, Dynamic Channel
Reconfiguration, Centralized Troubleshooting,
Alarm Messages, and Periodic Reports.
MUX. Sec. 1.2.4 and Sec. 1.4.
CABLING OH 4 The Back Panel provides Interface for Eight
Terminal/Port Cables, one Composite Interface
to modem cable and one Command Port Interface
Cable.
The Command Port is a Short Ribbon Cable
which exits in the Back Panel immediately
above the lower row of connectors and just
next to the Composite Interface Connector.
MUX. Sec. 2.3.
SWITCHES OH 5 Switches are accessed from the front of Stat.
Mux. after removing the Plexiglass Cover
Plate.
Switches are used for configuration means
of the Stat. Mux.
Switches for Reset, Local Test and Remote
Test are located next to the 8 position DIP-Switches.
MUX. Sec. 3.2.2.
MODULE OH 6 The Stat.Mux. provides a Module Display
to display the System Status and the Channel
Activity through the Plexiglass Plate.
The LED's in the D have three States:

15 One of the Optical Modems needs an extra inspection
on a specific Strap Setting before replacing a
malfunctioning one. Which one is that, where is
the Modem located, and what is the reason for the
extra inspection?
16 Control Characters are ruining the data transmission
on a V24 Line. Now you would like to get a Hard

Q̲U̲E̲S̲T̲I̲O̲N̲ ̲N̲O̲.: A̲N̲S̲W̲E̲R̲:
1 When changing FROM V24 to Optical Mode, the
signal interface cable is removed from A10.
A similar cable is connected from the Optical
Modem to the same connector on A10 (SIGNAL
INTERFACE CCA).
2 The Switch Panel Rotary Switches have three
positions each:
Pos. 1. Freq. Stab. Powers the Disk
Drive
Pos. 2. No Power
Pos. 3. Site Power is bypassed to Disk
Drive
The Frequency Stabilizer converts one power line
frequency to another with an output of 220V at
50 Hz.
3 The Output Voltage regulation is obtained by means
of a feedback signal from Transformer T3 and the
current limiting is obtained by feedback from Current
Transformer T4.
4 The Stat. Mux. provides the means of permitting
eight data channels to transmit data communications
sharing only a single communication line between
the Stat. Mux.'es.
5 The Local Test Mode tests a Stat. Mux. unit (need
not be attached to an operating unit). The Remote
Test Mode tests the Local and Remote Stat. Mux.
by causing
the Remote Unit to loop back all data for all channels.

NO ERRORS IN RAM
(printer prints 66 lines barberpole pattern)
7 The Default Baud Rate at Power-Up is selected
by four switches and is read by the Z80.

S2-6 & S2-5: Select number of stop bits
9 PRINT ALL/NORM

10 TTY - This method of remote communication
is character by character. Every keystroke
is sent to the host as hit by the operator.
BTTY - This method uses text buffer as a
buffer. Characters are entered but not sent
until the ENTER KEY is hit.
