RS-485/Ethernet Communication Selection
The MP9320 V2.8 is equipped with both RS-485 and Ethernet communication
ports. However, only one can be selected at a time. The reader is typically shipped
with Ethernet enabled. To enable RS-485 communication, perform the following:
Caution - ESD
The following procedures involve electrostatic discharge sensitive components. ESD
protection is required. Damage to the reader can occur if proper ESD equipment such as
grounded wrist straps and ESD protected work surfaces are not used.
1. Disconnect all power and communication cables from the reader.
2. Remove the outer reader cover by removing the 8 screws on each side and
carefully lifting the cover straight up.
3. Locate Jumper J4 on the connector end of the digital board (top board).
4. Move the jumper to Pins 1-2 (Pin 1 is closest to the end of the board).
5. To re-enable Ethernet communication, move the jumper to Pins 2-3.
6. Replace the cover and the 16 screws.
Serial (RS-232) Communication Setup
The MP9320 V2.8 is equipped with a 9-pin RS-232 communication port for
communication directly with a PC or other serial device. Refer to the
Specifications chapter for information on the port.
Figure 9–Standalone RS-232 Communication Setup
NOTE: A serial port adapter may be required if the device has a different connector type. For
example, some PCs may have 25-pin serial connectors.
