Digital (TTL) Input/Output Setup
The MP9210 is equipped with a digital I/O port that provides four logic-
level (TTL) input signals and four output signals. This port can be
programmed for specific applications using the FORTH interpreter built
into the reader.
North American Power Supply Installation
Power is provided to the MP9210 by a 120/240 Vac to 12 Vdc power
supply. Perform the following to install the power supply:
1. Insert the DC power connector into the connector on the end
panel of the reader.
2. Insert the power supply AC plug into a 120/240 Vac power outlet.
For international installations, refer to the following section.
Caution - Power Line Noise
The MP9210 reader is susceptible to excessive AC power
line noise and interference. If AC power line interference in
the range of 13.7–15 MHz or 26.5–27.9 MHz is present, the
tag reading function may be adversely affected. As a result, you may need
to install AC power line filters to remove the excessive interference.
