Additional Information
Port 1,2,3
Port 1 refers to the RS232 (9-pin) connector located on the
right of the Controller PCB. Ports 2 and 3 are TTL and are
labelled TX2/RX2 and TX3/RX3. On ports 2 and 3, the12v
supply should not be used to power devices – instead, use
12V supply from 3GS PSU.
Note Ports can be set to perform the same local
function (for example, 2 ports set for printer).
Baud rate
You can set up the panel for the baud rates ranging from
150 to 19200.
Parity, data bits and stop bits
Select the appropriate communications protocol.
Parity: E = Even Parity
N = No Parity
O = Odd Parity
Data Bits: 8/7 = 8 or 7
Stop Bits: 1/2 = 1 or 2
Printer
For direct connection to a printer this must be set to YES.
Serial Port 3 defaults to PRINTER: YES.
When set to YES, data is transmitted out to this port.
Transmit Name
The name and address entered during the initialisation
sequence of the system (usually after a cold start) can be
printed at the start of every logged text if required.
Pager
For connection to a local pager, set this to YES. Messages
will be formatted for the pager before being transmitted on
this port.
Log Filter
This controls which event types of logged data are output
to the serial port. It allows for filtering of log events based
on the log type. The log filter consists of a 16 bit word,
where each bit represents a log type. Each log type is listed
in the following table.
• Zone changes are controlled by bit 1.
• If the bit is SET, then reporting of zone changes is
ENABLED.
• If the bit is not SET, then the log type will be skipped
when reporting.
• Add the number of each log type together to generate
the appropriate log filter – for example, the default
value of 32767 allows all events
(1+2+3+......+15=32767).
