2.3 A 6505A SERIAL HUB CONNECTION GUIDE
Fig 2.3a shows the layout of the front of the A 6505A Serial Hub.
1
24V DC input
Connects to a 24V DC Plugpack with a 2.1mm Jack (Please observe the polarity, centre positive).
2
24V DC Input
Connects to a 24V DC source via a euro block (Please observe the polarity).
3
RJ45 interface
This RJ45 port is for connection to the A 6530 or A 6540 series wallplate wall plate.
4
PIR Trigger
This is used for connection to a PIR or other closing contact. (Note: When using the PIR trigger connection, the
jumper terminal (P1) on the A 6530 or A 6540 series wallplate has to be set to the PIR input (see section 2.1).
5
Power LED
Indicates the unit has power.
Fig 2.3b shows the layout of the rear of the A 6505A Serial Hub.
1
Serial Output 1
This output is configurable via the software as either an RS232 or RS485 output. The LED will illuminate while
data is being transmitted. Follow standard RS232 or RS485 wiring when connecting these terminals.
2
Serial Output 2
This output is configurable via the software as either an RS232 or RS485 output. The LED will illuminate while
data is being transmitted. Follow standard RS232 or RS485 wiring when connecting these terminals.
3
IR Output
These terminals are provided for connection to IR repeaters. The LED above the terminals illuminate while the output
is active.
4
DIP Switches
DIP 1 changes the IR LED voltage output, ON = 5V Direct, OFF = 5V @20mA to standard IR LED. DIP 2 is not used.
5
Output 1
This output provides a voltage free output with a normally open and normally closed contact. This is configured via
the software as the relay 1 output. (The maximum current rating of these contacts is 2A.) The LED above the
terminals illuminate while the output is active.
6
Output 2
This output provides a voltage free output with a normally open and normally closed contact. This is configured via
the software as the relay 2 output. (The maximum current rating of these contacts is 2A.) The LED above the
terminals illuminate while the output is active.
7
Output 3
This output provides a voltage free output with a normally open and normally closed contact. This is configured via
the software as the relay 3 output. (The maximum current rating of these contacts is 2A.) The LED above the
terminals illuminate while the output is active. (Note: the jumper terminal (P1) on the A 6530 or A 6540 series
wallplate has to be set to the Relay 3 input (see section 2.1).
