APPENDIX B1…01…***************…01……01…TECHNICAL REQUIREMENTS AND SPECIFICATIONS…01…FOR V24/V28 (L/L)-ADAPTORS
T̲E̲C̲H̲N̲I̲C̲A̲L̲ ̲R̲E̲Q̲U̲I̲R̲E̲M̲E̲N̲T̲S̲ ̲A̲N̲D̲ ̲S̲P̲E̲C̲I̲F̲I̲C̲A̲T̲I̲O̲N̲S̲
The V24/V28 (L/L)-adaptors (in the following V28(L)-adaptors)
to be supplied under this contract shall meet the specifications
and requirements specified in this appendix.
1̲ ̲ ̲G̲E̲N̲E̲R̲A̲L̲ ̲S̲P̲E̲C̲I̲F̲I̲C̲A̲T̲I̲O̲N̲
The V28(L) adaptor converts standard CCITT V24/V28 signal levels
within a data channel to low level signals. The adaptors shall
be implemented on a PC-Board (CAMAC, 5U) to be placed in a 19
inch TDX-crate. The crate will be mounted within a EMI-rack-assembly,
which privides high shielding effectiveness against electromagnetic
emanation to the environments.
Fig. 1-1 to 1-8 defines racks, crate and module. Two versions
of the V24(L)-adaptor shall be implemented. The functional requirements
to the two versions are defined in section 3 of this appendix.
The circuit design shall be based on Interim Report No. 3 dated
May 1, 1981, prepared by ARC for CR.
A sample of the 5u-Camac modules (fig. 1-4) to be used for the
two versions will be delivered to ARC by CR A/S.
In case of inconsistency between fig. 1-4 and the model, the
latter shall take precedence.
The front panels for the two versions are designed by CR.
The mechanical items for the modules (front panel, runners,
etc.) are supplied by CR. ARC integrates the modules completely.
The cables leaving the V28(L)-adaptor modules will be led through
a Filter Box (see appendix B2 of this contract).
The signals leaving the Filter Box shall comply with the following
requirements:
a) All electrical interconnections for data between the
equipment will use low level keying systems, i.e. 6-0-6
volts at currents less than one milli-ampere. All the
remaining control lines should conform to CCITT Recommendation
V28.
b) MIL-STD-188C
The design shall allow the adaptors to drive cable
lengths up to 900 ft.

3.2 I̲M̲P̲L̲E̲M̲E̲N̲T̲A̲T̲I̲O̲N̲
The two adaptor versions shall be implemented using
the same basic Printed Circuit Board (PCB). This PCB
shall fit in the CR 5u CAMAC mechanics and have an
edge connector (86 poled (A1-A43, B1-B43) towards the
CTX crate motherboard.
CTX Motherboard signals are shown in fig. 3.2-1 (the
version 1 adaptor) and in fig. 3.2-2 (the version 2
adaptor). (All the pins within the channel areas #1
to #4 are used).
To cope with the different configurations involved
in the version 1 and version 2 adaptors the PCB is
divided in 4 areas (refer to fig. 3.2-3):
a) 3 areas for a reduced configuration.
b) 1 area for an extended configuration.
This area contains as a subset the reduced configuration
area.
In the version 1 adaptor the 4 reduced configuration
areas will each be equipped as outlined in fig. 3.2.-4.
In the version 2 adaptor the extended configuration
area will be equipped as outlined in fig. 3.2-5.
The strap-options indicated shall be designed to allow
for re-programming in the field.
Initial placement of straps for production will be
specified by CR.

The module shall be able to be powered by two alternative
power sources. The source is selected by straps on
the module or an equivalent method.
These starps shall not be field exchangeable. The Version
1 - and Version 2 - modules to be supplied under this
contract shall be powered by AC-power.
a) DC-power (see. fig. 3.2-1 and 3.2-2).
available regulated voltage:
a1) + 5v
a2) + 12v
a3) - 12v
b) AC-power (see fig. 3.2-1 and 3.2-2)
b1) The module is powered by 2 x 9 VAC from a transformer
unit through 3 set of pins of the edge connector.
b1.1) Power input from the transformer unit:
9 VAC + 10%/- 15%
50 HZ + 10%/- 10%
b1.2) Harmonic distortion: Max. 5%
b2) The transformer unit converting to 2 x 9 VAC
nominal is shown on fig. 3.3-1..
The supply voltage is delivered from a centertapped
transformer, and must be rectified and regulated
"on board" to provide the necessary "on board"
DC voltages.
Each winding is capable of delivering 9V at

It is a requirement that the 2 adaptor versions
are designed so that the above mentioned available
power can support either one of the below mentioned
configurations:
