Internal connections


TB1 & TB2: +V/-V
These two Faston terminals are used for supply voltage connection

J1: Default I/O
It is a connector for a 14-pole flat cable allowing the connection to the module S81-T8004-1
(default I/O).

J2 & J3: LVDS Bus Loop Link
They are 2 RJ45 connectors for category 5 cable allowing to connect the CPU to the two peripheral
modules. This is a closed loop connection, thus allowing to increase system reliability. The J2 con-
nector (Bus-IN) must be connected to the BUS-OUT terminal of the last rack, whereas the J3 con-
nector (Bus-OUT) must be connected to the BUS-IN terminal of the first rack.
