Issue 4.5 August 2005 Europlex Universal Interface Card (EUIC) 11-7
H
ARDWARE
This section describes the main hardware features of
the EUIC.
The unit requires 12V DC @ 200 mA to operate.
The command string code and the serial port setup are
saved in non-volatile memory (that is, battery backed up
RAM). A reset switch (SW1) is provided to reset the unit
at any time.
Panel Port
This is the standard Europlex communication port
consisting of a 4-way terminal block. The four
connections are 0V, 12V, and Tx and Rx. This connection
supplies the power for the EUIC.
The port can be setup as follows:
●
baud rate: 1200, 2400, 4800, 9600, or 19200
●
parity: even, odd, or none
●
data bits: 7 or 8
●
stop bits: 1 or 2
Note Text in bold is the default setting.
LED 1 on this port will flash during communication with
the alarm system. It is recommended to use the
maximum speed setting to optimise system performance.
Host Port
The host port consists of port 1 (the video multiplexer
port) and port 2 (the PC port). That is, both port 1 and
port 2 share the same communication setup. This port
can be set up as follows:
●
baud rate: 1200, 2400, 4800, 9600 , or 19200
●
parity: even, odd, or none
●
data bits: 7 or 8 data bits
●
stop bits: 1 or 2
This has to be set to the default setting of the video
multiplexer.
Port 1 (P1 - Video Multiplexer Port)
This port consists of a 25-way male D-type connector.
RS232 signal levels are used. Tx data (pin 2), Rx data
(pin 3), and 0v (pin 7) are used. LED 2 on this port will
flash during communication on the port. Flow control is
provided, so the RTS (pin 4) must be connected to CTS
(pin 5) if no flow control is provided by the video
multiplexer system.
Port 2 (J3 - PC Port)
This port consists of a 9-way female D-type connector.
RS232 signal levels are used. Tx data (pin 3), Rx data
(pin 2), and 0v (pin 5) are used. LED 3 on this port will be
on to indicate that this port is operating. No flow control
is provided.
Default Link (J2)
This is a 5-way terminal block header (the terminal block
is not supplied). On power up of the unit or following a
reset, the PGM pin is checked. If PGM is connected to
12V, then the EUIC will load the default serial port setup,
the link should be removed for normal operation.
Housing
The EUIC is supplied as a PCB only. The mounting holes
and the size of the PCB are the same as the DM1200
(that is, the EUIC will mount in the same fixings as the
DM1200).
Serial Cables
No serial cables are provided with the unit, but should
be made up according to the details provided within this
chapter.
Serial cables compatible with the video multiplexer
system should be used on port 1.
If no flow control is provided on the video system, then a
null modem cable must be used.
A standard null modem cable can be used on port 2 for
PC connection.
