Camera to Host Connections Maps
The Host Interface of Coaxlink requires a specific assignment of the Device connections to the Host connectors. Such assignment is named Host Connection Map.
The Host Connection Map is hard-coded in the product/firmware variant. The Coaxlink product and firmware variant must be selected according to the required mapping!
Host Connection Map Naming Convention
The Host Connection Map or HCMAP designates how the connections of the Host Interface of a Coaxlink card are allocated to the Devices (cameras).
A Host Connection Map - HCMAP - is designated by an acronym using the following Euresys proprietary naming convention:
<dev#><dev-type>[<str#>S]{<con#>...<con#>}[<SL-con#>]
where:
| ● | <dev#>declares the maximum number of Devices (cameras) that can be attached to the Host Interface. |
| □ | 1 for a single-device Host interface |
| □ | 2 for a 2-device Host interface |
| □ | ... |
| ● | <dev-type> declares the device type. |
| □ | D for standard CoaXPress devices |
| □ | DF for virtual devices used in the Data Forwarding schemes |
| ● | <con#> declares the number of connections available for each device. This field is repeated once for each device. |
| □ | 1 for a single-connection device |
| □ | 2 for 2-connection device |
| □ | ... |
| ● | <str#>S declares the maximum number of data streams allowed by a device. |
| □ | This field is omitted when there is only 1 stream |
| □ | 4S for a up to 4 data-streams per device |
| ● | SL<-con#> declares the number connections per sub-link. |
| □ | This field is omitted when there are no sub-links. |
| □ | SL4 for a 4-connection sub-links |
Examples
HCMAP 2D22 designates a Host Interface with 2 standard 1-data-stream CoaXPress Devices and 2 connections for each device.
HCMAP 1D4S4 designates a Host Interface with 1 standard CoaXPress Devices, up to 4 data streams, and 4 connections per device.
