Situation 2
Preparation of a central PC
Objective
• To prepare a PC as main station, so that it will be ready to obtain
data and receive alarms from an external system.
Conditions
• New installation
• The different units must be connected to a voltage supply unit
• The PC must be mounted and Windows 7or XP must be installed
Procedure
1. Switch off all units, if they are on.
2. Mount a data communication cable between the AKA 241 PC
gateway and the AKA 245 modem gateway.
a) H to H and L to L
b) The screen must be mounted at both ends, and it must not
touch the frame or other electric connections (not either the
earth connection, if there is one)
c) Terminate the data communication cable (on both AKA
units).
3. Mount a serial cable between the PC and the PC gateway (can
be supplied by Danfoss).
4. Modem
a) Mount a serial cable between the modem and the modem
gateway (standard modem cable)
b) The supply voltage to the modem must be connected via
relay output DO1 on AKA 245 (reset function)
c) Connect the modem to the telephone network.
5. Set an address in the two AKA units
The address must be set via the control panel type AKA 21.
a) You may only energise one gateway at a time. Otherwise
there may be a conflict, because all the gateways come fac-
tory-set with same address
b) The modem gateway gives address 125
c) The PC gateway gives address 120
d) The network number is here the same and has to be set at
241 for both instances.
e) Remember to activate the function "Boot gateway".
6. Install the AKM programme on the PC.
During the installation a system address has to be set, among
other things, which is the AKM programme’s address (240:124).
And from the same display you push “Port setup” to define
which output on the PC is connected to the PC gateway (COM
1).
7. When the installation of the AKM Programme has been com-
pleted the two gateways must be prepared for communication:
a) Find the “AKA" menu
b) Select the line “Unknown AKA” and push “Router”
c) Indicate the system address of PC gateway (241:12 0). When
the AKM programme has established contact to this gate-
way, router lines must be set in it.
(The router line principle is described in Appendix 1, and
additional information may be obtained from the AKM
Manual).
