The LEDs display the TTL signal level, not the active status
of the signal. (TTL “high” → LED is on; TTL “low” → LED is
off).
In order to keep the loading of the signals as low as possible, the
LEDs are run through buffers.
For the incremental sensor signals, there are buffers with true
differential inputs. The pulse length of data signals (CAN, RXD, TXD,
SRXD, STXD) is extended to make even small blocks of data visible.
The power required by the LEDs is taken from the DS1103’s supply
voltage (VCC).
Electrical characteristics
BNC Connectors (CP1 ... CP28)
The CP1 ... CP28 connectors are female BNC connectors. Their shells
are connected to GND.
