3.8. SSINET (J302/J303)
The SSINet is designed for daisy-chaining encoder signals from one Ensemble HLe to another for two/three-
axis PSO (laser firing). This allows one Ensemble HLe containing the -DUALPSO or -TRIPLEPSO options
to track the vectorial position change of two/three axes in real-time. These encoder signals may also be used
for user-defined purposes. Refer to Figure 3-15 and Figure 3-6. These four channels are bi-directional and
configured via the SSINet1Setup and SSINet2Setup parameters; refer to the Ensemble Help File for more
information. The signals from these ports will be the same as the differential line driver encoder signal input
to the Ensemble HLe, unless the -MXH option is present.
N O T E : The SSINet #1 and #2 interfaces are both physically hardwired to the J302 and J303 connectors.
If SSINet #1 is configured as an input, a signal driven into the SSINet #1 connections on J302 will also be
present on the SSINet #1 connections of J303, effectively making SSINet #1 on J303 an (un-buffered) out-
put of this same signal. Likewise, this would also be true for the SSINet #2 interface.
