Power Source Requirements

The Panel Reader can be powered from a variety of DC power source options. The

recommended power source is the Allflex P/N 930014-002 AC/DC Power Supply,

which is housed in a steel NEMA 4X weather-tight enclosure, provides hermetic cable

entry clamps for panel reader, AC input power, and data, and provides convenient

internal terminal blocks on which to make panel reader cable connections.

Note 6 - A user provided AC power supply must be a “linear” regulated type unit rated at 6 to 12

VDC output and 3.0 amperes minimum. Some AC power supplies may exhibit excessive noise that

can compromise read range of FDX-B type transponders. Suitable AC power supplies should be rated

at 3 millivolts or less output ripple.

Note 7 - The Panel Reader does not contain a power on/off switch. When a power source is

connected to the designated power wires, the Panel Reader will commence immediate operation,

characterized by continuous reading. When powered from a battery source, be sure to disconnect the

battery when the Panel Reader is not in use in order to conserve battery life.

Note 8 - The Panel Reader is polarity protected against accidental reverse voltage application and will

not be damaged by such. However, reversing the power connections will prevent the Panel Reader’s

operation.

Serial Data Communications

The Panel Reader is provided with RS232 and with RS422/RS485 serial

communications interfaces. RS232 is generally used in short run (less than 15

meters/50 feet) configurations where the data recording equipment is provided with a

compatible RS232 interface. Longer cable lengths are possible also when data

communications rates are low (9600 bits/second and lower).

When long cable lengths are required between the Panel Reader and the data recording

equipment, when fast data communications rates (greater than 9600 bits/second) are

being used, or when bus communications are being used, the Panel Reader’s

RS422/RS485 interface should be used.

Note 9 - Serial communications for all interfaces are half duplex – that is, communication exists both

to and from the Panel Reader, but not simultaneously. While ID Code data is being transmitted from

the Panel Reader, communications to the Panel Reader cannot be received simultaneously.

Note 10 - RS232 and RS422/RS485 interfaces are concurrently enabled. At all times, the Panel

Reader can receive commands through either interface. However, both interfaces are coupled to a

single receive input pin on the Panel Reader’s internal circuitry. Consequently, if inputs are applied

simultaneously on both RS232 and RS422/RS485 interfaces, the commands will collide and be

unrecognizable to the Panel Reader. The user should employ only one of the interfaces for sending

commands to the Panel Reader.

Note 11 - Both RS232 and RS422/RS485 outputs can be simultaneously used. For example, the

RS232 output could be connected to a weigh-scale and the RS422 output could be connected to a data

recording device. Only one of these two user equipments should, however, have its transmit output

connected to the Panel Reader’s receive input, as is explained in Note 10.
