6 Digital Input/Outputs
The QuasarMR1 has 8 digital input and output pins (X2) which can be be read or set by
firmware commands via the reader. They are 5V TTL pins directly connected to the reader's
internal micro controller.
ATTENTION
Make sure the pins are not charged with a power exceeding 5V DC. Some
automation devices have an internal power of 24V (e.g. SPC, photoelectric
barrier, etc.). If 24V is connected to the pins of the QuasarMR1 without
appropriate protection measures, the device will be permanently damaged.
