BSAP Connection Settings Tab

Primary/Secondary Address Type

Type of addressing required to poll RTU.

Local (Default). Local addressing is used when the message does not have to pass through one or more other BSAP devices before reaching the one it's being sent to, and the BSAP device's address does not include an extra group number byte.
Global. Global addressing is used when the message must pass through one or more other BSAP devices before reaching the one it's being sent to.
EBSAP. EBSAP addressing is used when the BSAP device's address includes an extra group number byte.

For more information on how to determine which address type to use and the values of the fields required to use it, see BSAP Addressing from OpenBSI Netview.

Primary/Secondary Local Address

Default = 1. Local address used to poll RTU.

Primary/Secondary EBSAP Group Number

Default = 0. EBSAP group number used to poll RTU.

Primary/Secondary Global Address

Default = 256. Global address used to poll RTU.

The global address may be displayed by the device's configuration software as a hexadecimal number (ending in x), but it must be entered into ACM as a decimal.

For example, 21x = 33 decimal, 22x = 34 decimal, etc.

Primary/Secondary Device Level

Default = 1. RTU level in the BSAP network.

This should be one more than the number of other BSAP devices that the message must pass through before reaching the one it's being sent to. A device that receives its messages directly from the host computer (and therefore should use Local or EBSAP addressing) is at Device Level 1. A device whose messages pass through one other BSAP device is at Device Level 2, and so on.

Primary/Secondary Level 1-6 Devices

Maximum number of devices that can be connected at the specified level. These fields must be set correctly if the device is part of a BSAP network with more than one level. See BSAP Addressing from OpenBSI Netview for more information on how to find the correct values for these fields.

Primary/Secondary Line Initiation

Default = 1. Number of leading null bytes to send before each message.

Primary/Secondary No Data Retry Delay

Default = 100. The amount of time in milliseconds between receiving an acknowledgement with no data and sending another poll message to check again whether the data is now available.

Primary/Secondary VSAT Slave Mode

Default = Not selected. Select this option if the communication port at the RTU is operating in VSAT slave mode.
