The A-180-9 is a simple but useful tool that can be used to connect up to 14 signals between different cases by means of standard network cables (RJ45). These cables are readily available in different lengths and colours. The A-180.9i supplied with two modules and two 0.5m black RJ45 network cables.
The upper network connector is wired to the eight sockets 1-8, the lower to the six sockets A-F. That way it's possible to pre-patch different cases and connect signals, that are required in all cases (e.g. clock, start/stop, master CV) by means of one or two cables only instead of 14 individual patch cables.
When only eight signals are required only the upper network connector is required and the sockets 1-8 are used. When more than eight signals have to be patched both network connectors have to be used.
It's also possible to wire the upper and lower network to different cases (i.e. signals 1-8 to external case #1 and signals A-F to external case#2).
Note that the A-180.9 is purely passive and therefore does not need power, thus it’s power consumption is zero (0mA).
