OPERATION FROM A KUDOS ACTIVE FRONT PANEL FITTED TO A SHOEBOX
OPERATIONAL OVERVIEW
The ARC130S has provision to be remotely
controlled via two different interfaces, either S&W
RollCall, or RS422.
Interface to the "RollCall" communications network
is via the single BNC connector. Connections
should be made by means of a `T' piece (Zo=75
Ohms) to a 75 Ohm cable system as shown below.
It should be noted that both extremities of the cable
system must be terminated in 75 Ohms and the
maximum number of units limited to 240 on one
single cable run.
The communications network is a specially
designed remote control network system and many
more units can be accommodated by using a
"Network Bridge". Remote control can come from
either a dedicated front panel or "shoe-box" or a
standard IBM compatible PC. Full protocol
documentation and more detailed information is
available on request from the supplier.
The RS 422 remote control interface is via the 9-
pin female `D' connector. Protocol information is
also available on request from the supplier.
For more detailed information about the operation
of the remote panel or PC software please consult
their relevant manuals. e.g. Shoebox operator’s
manual.
For specific information about the RollCall menu
system for the ARC130S see Section 4, Operation,
RollCall Menu System
on page 4.34
BASIC ROLLCALL OPERATION
All the features from the menu system are
available remotely with the same options structure.
This maintains compatibility and facilitates easy
operation for users familiar with the unit.
The most common remote configuration is shown
below where many units are connected to the
network for remote control by one remote panel or
"shoe-box".
Typical Set-up
The network address for the ARC is set using the
switches SW3 and SW4 on the Output Interface
card. See fig 3.1 on page 3.8.
Parameter changes are reflected both locally and
remotely. For example, if the output is changed to
the colour bars test pattern by a remote unit then
any further access from the card edge to the
PATTERN TYPE option will indicate this change.
Similarly, if the card edge changes a parameter
then this will be reflected on the display panel of
the remote unit.
