The Séance box communicates with the PCs over a 10Base-2 Ethernet connection
via a 50 ohm BNC cable terminated at each end with a 50 ohm terminator. The
Séance box has two BNC connectors for each PC inter face, which are wired in paral­lel in side. A 50 ohm terminator plugs into the BNC socket labelled TERM INA TOR
and th e Ethernet cable plugs into the BNC socket labelled C O MPUTER. A termina­tor and T-piece are used to connect the Ethernet cable to the PC.

Each PC has a ‘one-to-one’ PS2 mouse cable, which co nnects between the PC’s
mouse port and the mouse connector on the rear panel of the Séance box. The
mouse plugs into the mouse connector on the front panel of the Séance box.

Converters are supplied to connect to a 5-pin DIN keyboard and 5-pin DIN connectors
on the PC.

The Séance interface reads the PC2 switch on the console’s CCM. The 5-pin XLR
connectors are paralleled together inside the Séance. A ‘female-female, one-one ca­ble ’ conn ects to the k eys conne ctor on th e CCM an d the ot her ca n be us ed to c onnec t

CADAC’s 15 way “f ast copper communications” cables are used to connect between
the Séance box’s fast comms connectors and the CCM. The cable plugged into Fast
comms PC1 on the Séance box must be connected to PC1 on the CCM.

Séance and SAM communicate over an Ethernet network using the TCP/IP protocol.
In ord er f or a succe ssfu l con necti on t o be mad e, each PC runn ing SAM ne eds to kno w
an IP address and port number of the Séance box and the Séance needs to know the
IP addr ess an d port numb er f or ea ch comput er runn ing S AM. Ind ivid ual IP a ddress es
must be different but the SAM port can be the same for each computer on the network.
The suggested settings are:

Séance IP address:194.222.033.010
Séance port:1111
PC1 IP address:194.222.033.011
PC2 IP address:194.222.033.012
SAM port:1112
SAM SETUP port:1113
Séance SETUP port:1114

When a Séa nce bo x i s ship ped fro m the f act ory the abo v e sett ing s are pr e-set . Matc h­ing settings are copied onto the PC the first time SAM is installed. If these values are
to be used for an installati on, the only settings that need to be ad justed are PC1 and
PC2’s IP address on each PC. See 2.6.1 and 2.6.2 for det ails (Note: This procedure
needs be carried out before you continue.)
In order to have SA M communicating with a consol e, the network interface needs to
be set up, see below:

41: 6$0#VHW0XS=

1. SAM’s PC needs TCP/IP networking installed and an IP address allocated.

2. SAM needs to know the IP ad dress of the Séance box (pre-set to

3. 194.222.33.10)

4. SAM needs to know the Séan ce bo x’s port numbe r (pre-set to 1111)

5. SAM needs to be given a port number ( pre-set to 1112)

41; 6pDQFH#VHW0XS=

1. Séance needs to be given a port number (pre-set to 1111)

2. Séance needs to know PC1’s IP address (pre-set to 194.222.33.11)

3. Séance needs to know PC2’s IP address (pre-set to 194.222.33.12)

4. Séance needs to know SAM’s port number (pre-set to 1112)

The set -up proced ure is di ff erent depe ndin g on which opera tin g syst em i s used on the
PC. SAM can run under Windows 95, Windows 98 or Windows NT. Each operating
system has it’s own set-up guide in the following pages.

41< 3RZHULQJ0XS#VHTXHQFH#RI#3&V

Always use the following pr ocedure:

Power-up cons o le

■■■■

Select PC1 on the CCM and power up the first computer. Wait until the PC1

■■■■

comput er has completed its boot-up routine, then. ..
Switch to PC2 on the CCM and power-up the second comput er and wait until it

■■■■

has completed its boot-up routine.
Power-up the Seance-box.

■■■■

Once both computers have booted correctly, they should allow the keyboard and
monitor to be switched back and forth without problems.

If the overall cable length for the keyboard and monitor are very long (greater than
5m), it may be necessary to use a keyboard and a monitor booster unit to retain key­board reliability and clean monitor display.
