If fl ow control is properly set, the messages should be received without loss when
attache d to a data tester, terminal or printer. In the case of printers, it is essential to
test flow control also under off-line conditions, as many have very large buffers which
can give a misleading indication that flow control is working when it is in fact not ever
requested by the printer.
4.3 Back-to-Back Testing
It is possible to test a pair of Esprits in a back-to-back mode usi ng a cable as descr ibed
in Appendix I
First ensure that both multiplxers ar e set to the same ty pe of composite interface, then
connect the two composite ports using the appropriate cable.
Set one mux to Internal Clock and also select an vali d r ate for it to r un at. Set the other
mux to External clock.
The m ultiplexers should establish carrier and perform exactly as if connected via a
digital service.
When you have finished any back-to-back testing, always set the cl ock back to External
as conflict will occur if it is connected to a digital data service.

APPENDIX C - EMC REQUIREMENTS
To ensure compliance with the EMC directi v e, some car e must be taken to ensur e that
the units are installed properly, using suitable cables and connections. The following
must be observed:
C.1 Limitation of Emissions:
C.1.1 'D-Type' Connections
This product r elies on the use of screened cables for connection to the 15 way and 25
way 'D-Type' ports. The cables must hav e the foil or braid scr een connected effectively
to the metal headshell to ensure continued compliance. The following headshells are
among those which have been found to provide suitable screen connection:
25 Way 15 Way
a) CINCH SCH25-K SCH15-K
b) RS 460-979 454-930
c) TOBY MHDTZK-25-K MHDTZK-15-K
The diagram below illustrates an example of a suitable screen connection. Note how
the foil or braid screen is bent back over the 'C' cl ip to achieve a pressure contact of the
screen against the shell:
It is important to keep the screen to shell connection as short as possible.
Esprit Statmux User Manual December 1997 Issue 1.3 Page 25 of 36
C.1.2 RJ45 Data Channel Connections
The RJ45 Channel Data connections do not normally require any shielding or ferrite to
meet emissions requirements, unless they are to be connected to other equipment that
does require a shielded cable, in which case suitable precautions should be taken.
C.1.3 Mains Connection
The mains connection is internally filtered and requires no special consideration.
C.2 To Ensure that adequate immunity is achieved:
It is in the user's interest to ensure continued product immunity against mains born
transients, and static discharge. To achieve this, it is important to ensure that
equipment is effectively earthed.
The m a in s IEC cable provides some protection, but to achieve optimal immunity, the
chassis EARTH screw connection should be connected to a local EARTH busbar or
cabinet frame wherever possible as shown below:

APPENDIX J - V24 Modem Connections & Setup
Modem setup example
Not all modems behav e identicall y, but the foll owing g eneric AT commands are a useful
starting point. One of the two modems must be set up as the Originator and the other
is set up as the Answering modem.
Set the Originator modem up as follows :-
AT &F0 Set Def aults
AT &M2 Set SYNCHRONOUS DTR dialling
AT &D2 DTR required for modem to go online
AT &S1 DSR Responds to remote modem
AT &Z0= tel No Set telephone number
AT &W Save settings
Set the Answering modem up as follows :-
AT &F0 Set Def aults
AT &M1 Set SYNCHRONOUS mode
AT &D0 Ignore DTR
AT &S1 DSR Responds to remote modem
ATS0=1 Set answer to 1 ring
AT &W Save settings
Connect the composite link of the local multiplexer to the calling modem and the remote
to the answering modem using an X.21bis/V.24 Straight cable.
