5.6 MIK-48 INTERFACE MODULE
The interface module is used to connect external devices to the control panel.
The following elements are located on the interface panel:
-
one universal USB serial port connector:
-
ZP1 - PORT 1 - computer, PMC-4000 monitoring, TELSAP 2100 monitoring
-
two 9-pin EIA RS-232 standard serial port connectors:
•
ZP2 - PORT 2 - computer, PMC-4000 monitoring, TELSAP 2100 monitoring;
•
ZP3 - PORT 3 – computer, PMC-4000 monitoring, TELSAP 2100 monitoring, bar code
reader.
Moreover, the panel is equipped with RS-485 standard serial connector terminals:
-
”A”, ”B”, ”CHGND” - output to the TSR-4000 terminal.
All module outputs are galvanically isolated from the control panel.
Note:
When control panels operate in an optical fibre version of the network, an optical fibre converter
supplied with the control panel power removes the galvanic isolation. In this case, connecting a PC
supplied from mains results in the earth fault signal emission. Thus a PC connected to the control
panel must always be supplied from the same point of mains as the panel. Otherwise, the difference
between the PC and control panel "mass" may result in the MIK-48 module outputs fault.
The above may also be caused by connecting a monitoring system. That is why the monitoring
system must be equipped with a galvanically isolated input.
However, the best solution is to use an external power supply adapter to support the optical fibre
converter – see p. 9.1 Note.
Each serial port is declared (see the programming manual [PM]) and may be used for different
purposes according with the declaration. An RS232 port should be connected with an external device
by means of a standard PC cable connecting devices with COM type serial outputs. See section 5.6.2
for instructions regarding an RS485 port connection.
MIK-48 is equipped with a ZK1 connector to install a PS/2 keyboard which may replace the keypad
provided in the handling area. Moreover, the keyboard is necessary to enter user's messages. The
connected keyboard may not be declared.
