Serial Radio EIE

The Serial Radio EIE communication device is a specialized version of the Direct Serial EIE communication device. It adds configuration options to allow control of a directly attached serial radio which communicates with remotely located devices.

Serial Radio EIE Device Editor

A 64-bit version of this EIE is available. See 64-bit Device Drivers.

Properties

The following table lists and describes properties from the Serial Radio Device Editor dialog box.

Property

Description

Device ID

The unique identifier of an instance for this device. This free-form name must be unique in the DDS and the FAC. That is, it must be a name not used by any other communication device, import/export device, remote device, or facility.

CygNet naming standards for device ID are as follows:

Component

Valid Character Set

Limits

Device ID

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z (uppercase)

0 1 2 3 4 5 6 7 8 9

dash (-), underscore (_), and tilde (~).

Note: Tilde (~) is a valid character for both devices and facilities, but its use is not recommended.

20 character maximum

No spaces

Description

A free-form description of the device. 32 character maximum.

Message delay(msec)

The delay (in milliseconds) to wait before sending a message to the remote device. If the remote device also has a message delay, the greater value takes precedence.

Host mode

Listen This mode indicates that the communications device can only listen to a data stream from an external source. This mode is also implemented on a per remote device EIE basis.

Master This default mode allows any message to be sent.

NonMaster This mode is remote device EIE-specific. It is not designed to allow write messages to be sent to an RTU. However, because each remote device EIE specifies what a write message is, you might still be able to send some write messages.

Device class

Not applicable in most instances.

Radio settings

Modem warmup(msec)

Time (in milliseconds) to allow the modem to warm-up.

Key hold time (msec)

Time (in milliseconds) to hold key signal high to allow bytes to be sent.

Ignore parity errors

Flag to ignore parity errors.

Radio key type

Signal type to activate radio.

Port settings

COM port

The port to which the communications device is connected. You can type a port number in the box if necessary. The CygNet Universal Interface Service (UIS) takes control of the communication ports for which Comm Devices are defined and enabled. To release the port you must disable the communications device or stop the UIS.

Bits per second

COM Port bit speed. The port speed and device speed must match.

Data bits

Number of data bits.

Parity

Parity type.

Stop bits

Number of stop bits.

Flow control

Handshake signal.

Enable device

Select whether to enable or disable the device. The default setting is disabled. If an invalid configuration is detected, the device will automatically be disabled. The device can be re-enabled after the invalid configuration is fixed.
