l

CS I/O ME Master: The CS I/O port is used and configured for direct connection to a CSI
COM220 or other modem enabled (ME) device such as an MD485. The connection is a type
of “null modem” that crosses TX and RX, and ME and RING; this line swapping is done by
using an A100. The baud rates of both the COM220 (or other device) and the RF451/RF452
must be the same.

l

USB: The USB port is used when connected to a computer.

7.1.2 SDC Address

Specifies the SDC address that will be used on the RF451/RF452 CS I/O port when CS I/O SDC is
selected as the Active Interface.

7.1.3 Baud Rate

Specifies the baud rate that will be used on the RS-232 port.

7.1.4 Radio Operation Mode

The Radio Operation Mode option designates the method RF451/RF452 transceivers use to
communicate with each other. RF451/RF452 transceivers operate in a gateway-to-endpoint
configuration. Before the transceivers can operate together, they must be properly set up to
communicate.

When setting up the transceiver, remember that a number of parameters are controlled by the
settings in the gateway. Also, radio network diagnostics can only be accessed at the gateway
radio. Therefore, it is recommended that you deploy the gateway on the communications end
where it will be easier to access.

l

Gateway: This operation mode designates the radio as the gateway. This mode allows the
gateway to communicate simultaneously with numerous endpoints, repeaters, and
endpoint/repeaters. There can be only one gateway radio in the radio network.

l

Endpoint: This operation mode designates the radio as an endpoint. This mode allows the
endpoint to communicate with the gateway. The endpoint will send packets received from
the gateway to the device attached to the active interface (CS I/O or RS-232) and send data
received from the device attached to the active interface to the gateway. Endpoints may
communicate with the gateway through one or more repeaters and/or endpoint/repeaters.

l

Repeater: This operation mode designates the radio as a repeater. This mode allows the
repeater to repeat packets sent across the radio network to the gateway, endpoints, other
repeaters, and endpoint/repeaters. Repeaters may communicate with the gateway through
one or more other repeaters and/or endpoint/repeaters.
