Vendor Specific Class (VSC)
The vendor specific class implements a single USB to high-speed Watbus gateway (Watbus Over USB).
This connection provides access to the RMA PLUS and all devices connected to the high-speed Watbus
network. Transactions intended for remote devices are proxied (routed) through the RMA PLUS to the
high-speed Watbus network.
Mass Storage Class (MSC)
The RMA PLUS provides three disk drives for user access. Upon connection, the drives are stopped. This
means the firmware has control of the drive. The user may request exclusive access of the drive by
pressing the “
E
ject” button in Windows
® Explorer. This sends a start / stop command to the device.
When the PC mounts the drive, all firmware services that use this drive are suspended. For this reason,
it is important to use the “
E
ject” button to stop the drive and give control back to the firmware when
you are finished with it. It is also important to stop the drives before removing the USB cable to prevent
data corruption.
Each disk drive is enumerated with a Logical Unit Number (LUN). Windows® may mount them in any
order even though they are enumerated as follows in firmware:
LUN 0: MICRO SD
Volume: (sd:)
LED Instance 1 (A) indicates the drive state by default.
The product ships with a 4 GB class 4 micro SDHC card (FAT32) for standard models and a 16 GB class 10
micro SDHC card (FAT32) for data logging models.
It is intended to be an extension of the product’s
memory and not removable at runtime. The SD card is primarily used for data logging, serving web
pages, software and documentation distribution.
NOTE: The RMA PLUS will not function properly without the SD card inserted. If necessary, the user may
upgrade the SD card to a larger capacity and / or class so long as the new card is high capacity (SDHC).
Extended capacity micro SD cards (SDXC) are not supported by this device.
LUN 1: NOR FLASH
Volume: (nor:)
LED Instance 2 (B) indicates the drive state by default.
This is a 10 MB FAT16 partition on the internal flash memory. Its primary use is for product
configuration because of its speed and persistence compared to the SD card. This is where
configuration files live by default.
LUN 2: RAM DISK
Volume: (ram:)
LED Instance 3 (C) indicates the drive state by default.
The RAM disk is a 1 MB FAT12 partition on the external SDRAM chip. This is volatile memory. Any files
directed here will be lost when the product resets. By default, only the event log is stored here.
