2. Operation overview
Standard s88-N
The standard s88-N regulates the assignment of commercial Ethernet
patch-cables with RJ-45 connections for use in s88 feedback systems.
Unlike the 6-conductor connecting cables frequently used, the patch-
cables used in computer networks are screened against outside electric
signals. Thus using patch-cables reduces the liability to interference
considerably.
Adapters S88-A
The adapters S88-A have connections for both an Ethernet patch-cable
(RJ-45) according to the standard s88-N and a 6-conductor s88-
connecting cable. They allow
to connect advices for the s88 bus with customary 6-pin connections
via patch cables (RJ-45) to each other;
to connect an advice for the s88 bus with customary 6-pin
connections to a s88-device with RJ-45 connections according to
s88-N.
Versions of the adapters S88-A
The adapters are available in four different versions for different
mounting situations:
Version of the adapter´s
6-pole connector
S88-A-BR socket
S88-A-BL socket
S88-A-SR plug
S88-A-SL plug
Connection socket or plug?
If there is space available and if the adapter can be securely mounted
to the s88 device, it makes sense to use adapters with sockets. With
some devices it is impossible securely mounting an adapter with socket.
With those devices connecting an adapter with connecting plug via a
short 6-conductor connecting cable (e.g. S88-15) is recommended.
Direction "central unit" or "following module"?
The wires of the s88-data line are numbered from 1 to 6 and are
assigned differently. In order to ensure the data transfer, the wires 1 to
6 have to be connected continuously to each other. Normally, the s88
feedback modules are designed so that the flat 6-conductor connecting
cables do not have to be twisted.
For this reason the adapters are available with two different PIN
assignments. The version "R" is used with those s88 devices showing
their 6-pole connecting plug in direction of the central unit, the version
"L" for those modules and devices showing their 6-pole connecting plug
in direction of the following module.
Examples for possible mounting situations
Explanations for the examples:
1
The central unit shown does not allow connecting an adapter
with socket. That is the reason why the connection is made via a
short 6-connector connecting cable and an adapter with plug. As
the central unit´s connection shows in direction of the following
module, an adapter version "L" is required
2
This version of a s88 module allows you to fit adapters with
3
socket directly. At the modules connection showing in the
direction of the central unit an adapter version "R" is used, at the
connection showing in the direction of the following module an
adapter version "L" is used.
4
With this version of a s88 module, no adapter with socket can be
used. For this reason the connection is made via a short 6-
connector connecting cable and an adapter with plug. As the
module´s connection shows in direction of the central unit, an
adapter version "R" is required.

3. Mounting the adapter
Connect the adapter to the patch cable and the s88 feedback module or
device. For this purpose use an adapter with socket or an adapter with
plug and a short 6-connector connecting cable.
Caution:
!
Avoid constructions which allow the adapter to be moved after having
been connected. Due to (involuntary) movements of the adapter the
connections of the s88 module or the digital device and their mounting
can be damaged.
4. Check list for trouble shooting
The central unit, the memory or the interface do not show the proper
status.
Possible cause: The connection(s) between the adapter and the
connected
device
and
/
interrupted. Check the connection(s).
Possible cause: You have mounted an adapter not corresponding to the
set mounting direction. Check if mounting direction and the chosen
adapter correspond to each other and, if necessary, exchange the
adapter.
Hotline
If problems with your module occur, our hotline is pleased to help you
(mail address overpage).
Repairs
You can send in a defective module for repair (address overpage). In
case of guarantee the repair is free of charge for you. With damages
not covered by guarantee, the maximum fee for the repair is 50 % of
the sales price according to our valid price list. We reserve the right to
reject the repairing of a module when the repair is impossible for
technical or economic reasons.
Please do not send in modules for repair charged to us. In case of
warranty we will reimburse the forwarding expenses up to the flat rate
we charge according to our valid price list for the delivery of the
product. With repairs not covered by guarantee you have to bear the
expenses for sending back and forth.
5. Guarantee bond
For this product we issue voluntarily a guarantee of 2 years from the
date of purchase by the first customer, but in maximum 3 years after
the end of series production. The first customer is the consumer first
purchasing the product from us, a dealer or another natural or juristic
person reselling or mounting the product on the basis of self-
employment. The guarantee exists supplementary to the legal warranty
of merchantability due to the consumer by the seller.
The warranty includes the free correction of faults which can be proved
to be due to material failure or factory flaw. With kits we guarantee
the completeness and quality of the components as well as the function
of the parts according to the parameters in not mounted state. We
guarantee the adherence to the technical specifications when the kit
has been assembled and the ready-built circuit connected according to
the manual
and when start and mode of operation follow the
instructions.
We retain the right to repair, make improvements, to deliver spares or
to return the purchase price. Other claims are excluded. Claims for
secondary damages or product liability consist only according to legal
requirements.
Condition for this guarantee to be valid, is the adherence to the
manual. In addition, the guarantee claim is excluded in the following
cases:
if arbitrary changes in the circuit are made,
if repair attempts have failed with a ready-built module or device,
if damaged by other persons,
if damaged by faulty operation or by careless use or abuse.
