7.2.2  Example: Several units connected by NCB 

Messages sent to the RS232 of a single unit will be returned once no matter what address or input/output 
number the message has, unless it is a matrix which recognizes one of the conditions a) or b) above. 
If none of the cases a) or b) is fulfilled the message will also be transmitted on the NCB. Then if any unit 
on the NCB ring recognizes any of the cases a)/b) or c), the message will stop at that point. This means 
that the message will only be returned once on the RS232. 
However, if none of the units on the NCB recognizes any of the cases a) to c), the message will return to 
the originator (the unit which received the message on RS232). This unit will re-transmit the message 
once more on both NCB and RS232. The message is therefore returned a second time on RS232. This 
time one of the cases a) or c) is sure to be identified by one of the units on the NCB, and the message is 
removed. 
There is however one more special case: If several messages for unused addresses are transmitted with 
only little delay, one might experience that some messages are returned several times, as the 
store/compare/remove function in case c) can only handle a single message at the time. We therefore 
recommend that the user avoid sending messages to unused addresses. 

7.3 RS232 

The RS-232 port is used for external control of Triton units. The RS-232 port allows the customer to 
control the equipment via the Triton Router Control System PC program or self-defined customized 
solutions. 
Connector for the RS-232 port is a DS9 female. 
 
Pin 2 - Tx. 
Pin 3 - Rx 
Pin 5 - GND 
 
A standard DCE (Data Communication Equipment) cable can be used for connection between PC and 
Triton equipment. The connection between the connectors is made one-to-one. 
Data-rate is 19200 baud/sec with 8 data-bit, 1 stop-bit, no parity, if nothing else is specified in the user 
manual of the product. 

7.4 NCB 

The NCB is used for interconnection between several Triton units. Up to 20 routers and/or control panels 
can be linked together to form a routing system with many operational features. 
 
The NCB utilises a 5 mA current loop with opto-coupled ports. 
Standard connector is a 5pin DIN. 
 
Standard MIDI cables can be used to interconnect several Triton units. 
Data-rate is 31.25 Kbps.  
1 start-bit, 8 data-bit, no parity, 1 stop-bit. Logical 0 = current ON.
