2Functional specifications
The Alfanet PC-Interface 2e gen. is provided with a real-time clock and display. This interface has
been developed as an intelligent interface between a Personal Computer (PC) and the RS485
network. The interface takes care of the communication between the PC and the network and is in
principle a transparent intermediary for messages from PC to the RS485 network and vice versa.
The interface can also store messages and log data in its internal buffer when the PC is not available
for communication with the interface or in case the PC is turned off.
Of all the messages coming from cool panels there are two messages to activate the relays on the
interface;
1) an alarm message to active relay 1
2) a log-buffer full message to active relay 2
The communication program for the PC requires MS Windows®.

2.1 Installation
On the connection diagram of the Alfanet PC-Interface is shown how the RS485, RS232 or
USB, supply and relays must be connected.
After connecting the Alfanet PC-Interface to the power supply, a self-test function is started,
after this the current time is shown in the display.
2.2 Control
The Alfanet PC-Interface can be controlled by three pushbuttons. These buttons are:
SET - view / change value of setting.
- changing between real time and % log buffer full on the display
UP - increase value of setting / readout UTC-time.
DOWN - decrease value of setting.
2.3 Setting internal parameters
For setting the clock, summer/winter time and the log-interval there are several internal
parameters available.
To enter the internal parameter menu the DOWN key must be pressed for more than 10
seconds. In the left display the upper and lower segment are blinking. Over the UP and
DOWN keys the required parameter can be selected (see table for the parameters).
If the required parameter is selected, the value can be read-out by pushing the SET key.
Push the UP or DOWN key to change the value of this parameter.
If 20 seconds no key is pushed, the Alfanet PC-Interface changes to the normal operation
mode and the changes are stored.

Explanation P01 setting clock:
After selecting parameter P 01 the clock can be set by pushing the SET key. The procedure
is as follows;
- At first the hours are set (0..23) with the UP and/or DOWN key.
- Press the SET key to confirm the value.
- Next the minutes are set (0..59) with the UP and/or DOWN key.
- Press the SET key to confirm the value.
- Next the year is set (0..9999) with the UP and/or DOWN key.
- Press the SET key to confirm the value.
- Next the month is set (1..12 = Jan..Dec) with the UP and/or DOWN key.
- Press the SET key to confirm the value.
- At last the day is set (0..6 = Mo .. Su) with the UP and/or DOWN key.
- And close the procedure by confirming the value with the SET key.
Explanation P32 detection lost controller:
If this parameter = 1, the interface will generate an alarm when the communication with one
of the controllers is lost. The interface will try to get connection with the lost controller for 5
minutes. If this failes, the alarm led and the relay will be activated. The alarm can be reset
with the SET key.
Explanation P50 setting log interval:
Normally the log intervals are set using the program on the PC. It is also possible to set the
log interval per network number without the PC. Press the SET key once after selecting
parameter P50 to set the log intervals as follows;
- The display shows ‘n 1', were the number behind the ‘n’ is network number 1.
By pressing the SET key again the log interval time is shown on the display. Value
‘0000' means off. The shown value can be changed by pressing the SET key
simultaneously with the UP or DOWN key. After releasing the keys the display
shows ‘n 1' again.
- To select an other network number use the UP and/or DOWN keys, f.i. ‘n 2'.
To change or readout the log interval time of this network number use the same
procedure as above.
At this way all log interval times of the network can be changed.
As for several seconds no key is pressed the PC-Interface returns back to it’s normal
operation.
3Program
3.1 Installation

4Operation of relay outputs
The PC-Interface has two relays. All contacts are available from both relays at screw terminals.
Relay 1 The function from this relay can be adjusted with parameter P30.
A control alarm means that the relay will be energized when an alarm occurs.
A fail save alarm means that the relay is energized in normal operation an when
an alarm occurs it will be not energized if one of the connected panels on the
network has sent an alarm message.
Pulse means that the relay will be energized for 3 seconds if there is an alarm.
Relay 2 The function from this relay can be adjusted with parameter P31.
If the relay will be used as Log-buffer-full relay, the relay will be energized as one
of the connected panels on the network has sent an buffer-full message. It also will
be deactivate if the memory from the interface is full for 90%.
The function “external alarm” is for future purposes and is not active in this
moment.
