5.10 INVENTORY CHECK
5.1 U̲N̲P̲A̲C̲K̲I̲N̲G̲
a) The EMI shielded rack for the Protocol Converter
is packed in its original wooden container.
The rack should remain packed during site internal
transportation and only be unpacked close to the
installation site, but if the space along the access
route is limited, the rack can be unpacked before
transportation to the installation site. The racks
is unpacked as follows:
b) Remove the top cover of the wooden container by
demounting the 3 ea 1/4 x 2.1/2" bolts on each
side of the continer and the 4 ea 1/2 - 13 x 2"
bolts, one in each top corner (see Figure 5.1-1).
c) The 4 walls of the container are removed by loosening
the 21 ea 1/4 x 2.1/2" bolts on each short side.
d) The rack is bolted to the container bottom in each
corner by a 1/2 - 13 x 2.1/2" bolt.
e) These bolts are removed from the bottom of the
container.

6.2 S̲y̲s̲t̲e̲m̲ ̲I̲n̲i̲t̲i̲a̲l̲i̲z̲a̲t̲i̲o̲n̲
As a result of a "power up" or a "Master Clear" button
activation the PC enters the Maintenance Mode.
The system will at any time be in one of four modes,
each mode defining a state with certain capabilities.
The system modes are:
a) Maintenance Mode
b) Local Mode
c) Operational Mode
d) Test Mode
The system is controlled by an operator who - via the
maintenance VDU - communicates with the system giving
commands and receiving responses. The execution of
a command may change the current mode of the system
and the current mode defines which commands are accepted.
The system will display a prompt on the VDU when ready
to receive a command. This prompt will also show the
current mode of the system.
Once the system is brought into operational mode, the
VDU may be dis-patched from the converter which will
continue operating unaffected.
The relationship between modes and commands is depicted
in Figure 6.2-1 and further described in ref.u.

On each module front panel, a green LED marked "POWER"
indicates that the primary power is applied to the
module and that the power regulators are operating
satisfactorily.
6.3.3 L̲T̲U̲ ̲I̲n̲d̲i̲c̲a̲t̲o̲r̲s̲
3 LED's are mounted on the front panel:
POWER: green Indicates when +12, -12
and +5 power supply is
present at the module.
BOOTL: yellow Indicates when the LTU
is in Bootload Mode.
TEST: red If the selftest of the
LTU has succeeded, the
LED is turned off. If
failure, the LED is flashing.
6.3.4 O̲P̲T̲O̲ ̲T̲/̲R̲ ̲I̲n̲d̲i̲c̲a̲t̲o̲r̲s̲
The OM-1 and OM-2 have the same status display functions.
Five LED lamps provide a continuous indication on the
status of the OPTO T/R.
PWR: This green indicator should be on continuously.
It indicates that primary power is applied to the OPTO
T/R and that the power regulators are operating satisfactorily.
RCVL: This red indicator should be off during normal
operation. When this LED is on it indicates that the
amplitude of the receive signal is within 3 dB of the
minimum acceptable level; or that the frequency of
the received signal is not correct.
RTS: This yellow indicator will be on whenever the
Request to Send input is present from the associated
device.
CTS: This yellow indicator will be on whenever a Clear
to Send output is applied to the associated device.
SYNC: This red indicator should be off during normal
operation. When this LED is on it indicates that the
OPTO T/R is attempting to establish synchronization.
6.3.5 V̲.̲2̲8̲ ̲L̲/̲L̲ ̲A̲d̲a̲p̲t̲e̲r̲ ̲I̲n̲d̲i̲c̲a̲t̲o̲r̲s̲
The only status lamp on the V.28 L/L Adapter is the
green power-on indicator.
An ON condition indicates that the primary power is
applied to the adapter and that the power regulators
are operating satisfactorily.
6.3.6 V̲D̲U̲ ̲S̲t̲a̲t̲u̲s̲ ̲I̲n̲d̲i̲c̲a̲t̲i̲o̲n̲
a) Upon power-up, the power-up diagnostic test (flickering
pictures) determines the amount of RANDOM ACCESS
MEMORY (RAM) installed, and executes a diagnostic
test to check RAM. EPROM is also checked and checksums
are then computed and compared against the value
stored in the ERASABLE PROGRAMMABLE READ ONLY MEMORY
(EPROM) at locations FFEC-FFFBH.
If a RAM memory error is found, the following message
is displayed:
MEM ERR: ADR XXXX YY
ZZ
where XXXX is the hexadecimal address.
YY is the contents of that address.
ZZ is the expected value.
If the EPROM checksums are incorrect, the message:
BAD EPROM CHECKSUM xxxx xxxx
....
(where xxxx= addresses of the bad EPROMS)
is displayed along with the DIAGNOSTIC menu.
If the RAM and EPROM checksums are good a clear
screen will occur with the words TTY RESET above
the status line.
b) For use of Diagnostic Menu and other diagnostic
and status function refer to the VDU Technical
Manual
(ref. p.).
