4 General about SattBus installation
A shielded twisted pair cable with a minimum
of 3 twists/m and 80–120 Ωcharacteristic
impedance should be used as the bus cable.
Minimum area is 0.35 mm 2.
Note! The same type of cable must be used for
the entire SattBus installation.
Cable length and number of nodes
The total length must not exceed 500 m.
Termination
The bus cable should be terminated with
100 Ωresistors, connected at the two most
remote ends, measured along the cable. See
figure above.
All units in EPC 50 system, i.e. OP, I/O and
MT 50, have internal termination resistors
which can be connected/disconnected by
jumpers.
For EPC 50 I/O-board termination resistor is
connected by placing jumper XJ3 in position
TERM.

4 General about SattBus installation EPC 50 Service Guide
12 493-1077-11 (0-3)
For MT 50 the termination resistor is con-
nected by placing a jumper wire between ter-
minal no. 5 and 6 in connector X3.
For EPC 50 Remote OP the termination resis-
tor is connected by placing a jumper wire
between terminal no. 5 and 6 in connector X1,
i.e the screw terminal in the panel box.
At the PC, a 100 Ωtermination resistor should
be connected in the SattBus connector. This is
valid for both SattBus PC board and SBSU
unit.
IMPORTANT! Only two termination resistor,
one at each end, of a SattBus network must be
connected!

5 Hardware Installation
This chapter describes how to connect the PC
with REMIND EPC50 Network installed, to
EPC 50 Control Cabinets via SattBus
network. Up to nine EPC 50 Control Cabinets
can be connected.
Warning! When handling electronics, avoid
electrostatic discharge e.g. by wearing an ESD
bracelet.
5.1 Overview
SattBus interconnects the EPC 50 units,
MT50, OP and I/O module, in the EPC 50
control system. See figure below.
An optional remote OP may also be connected
to SattBus.
A PC with REMIND™ EPC 50, Network can
be connected to SattBus in two alternative
ways:
•to SattBus via a SattBus PC board which
is mounted inside the PC. (REMIND™
EPC 50, Network Kit, PC-card art.no.
31830-6410-1)
•to SattBus via a SattBus Serial Unit,
SBSU. One of the serial ports of the PC is
then used. (REMIND™ EPC 50, Network
Kit, SBSU art.no. 31830-6411-1).

5 Hardware Installation REMIND™ EPC 50 Network User´s Manual
14 493107611 (3-1)
A maximum of 9 EPC 50 Control Cabinets
can be controlled and monitored by the PC
with the REMIND™ program.
The two alternatives for REMIND™ EPC 50,
Network.
5.2 Connect a PC to
EPC50 Control
Cabinet using a
SattBus PC Board
This is an alternative which connects the
SattBus network directly to the PC using a
SattBus PC board. Below is a step-by-step
description that shows how to connect the PC
to a single or the first one of several EPC 50
Control Cabinets.

5.3 Connect a PC to
EPC50 Control
Cabinet using a
SattBus Serial Unit,
SBSU
This alternative connects SattBus to the PC
via a SattBus Serial Unit, SBSU. Below is a
step-by-step description that shows how to
connect the PC to a single EPC 50 unit or to
the first of several EPC 50 units.
1. Remove the cover from the SBSU unit and
set the switches as described below. The
SBSU layout, function etc. is described in
‘‘SattBus Serial Unit, SBSU Description’’
on page 39.
Node identity
Set the node address to 19 for control and
monitoring. If node address is set to 18 only
monitoring is possible. The address is set by
the two hexadecimal switches “Node
identity”. See chapter ‘‘SattBus Serial Unit,
SBSU Description’’ on page 39.
Set switch marked “H” to "1" and switch
marked "L" to "3" for control and monitoring
or to "2" for only monitoring.
Other settnings are described in chapter
‘‘SattBus Serial Unit, SBSU Description’’ on
page 39.
Filter address
All four switches SW1–SW2 must be set to
zero.

5 Hardware Installation REMIND™ EPC 50 Network User´s Manual
18 493107611 (3-1)
Mode switch
The mode switch SW must be set to zero, see
chapter ‘‘SattBus Serial Unit, SBSU
Description’’ on page 39).
Serial channel parameters
The DIP switch below the node identity
switches (see chapter ‘‘SattBus Serial Unit,
SBSU Description’’ on page 39) is used to set
the serial channel parameters. Normally 9600
baud, no parity (SW1 - 5), and "Host interface
mode" (SW6 - 8) should be chosen.
Other settings are described in ‘‘SattBus Serial
Unit, SBSU Description’’ on page 39.
2. Mount the SBSU unit close to the PC by
means of 4 screws or a DIN rail. The unit
needs a power supply, see the step below.
The unit is described in ‘‘SattBus Serial
Unit, SBSU Description’’ on page 39.
3. Connect 24 V DC from the power supply (
art.no.: 490083613) to the SBSU 3-pole
jackable screw terminal block (marked
“POWER”). A suitable cable is 3 × 1.5
mm 2 . The voltage at the terminal screws
must be 19–32 V DC. Connect protective
ground to the relevant terminal screw, and
connect 0 V to ground only at one end of
the cable.

4. Use the serial communication cable (RS-
232, art.no.: 490173740) for connection
between the serial port of the PC and the
SBSU unit (channel 1). Maximum cable
length is 15 m. Use a screened cable and
connect the screen to the metal case of the
connector. Use a 25-pole metallic male D-
type connector on the SBSU side. The
electric diagram below shows the required
connections.
5. Connect the SattBus cable to the 4-pole
plug-in screw connector, ‘‘SattBus Serial
Unit, SBSU Description’’ on page 39. The
connector is delivered with the SBSU.
Connect the other end to connector X3: 1
and 2 on EPC 50 I/O board in EPC 50
Control Cabinet.
