			== Protocol ==

			The encoder uses a full duplex RS-422 UART to connect to the host:

			{\| class="wikitable"
			! Baud Rate
			\| 2,500,000
			\|-
			! Data Bits
			\| 8
			\|-
			! Stop Bits
			\| 1
			\|-
			! Parity
			\| none
			\|}

			For interacting with the encoder from a PC, a USB to serial supporting a higher than usual baudrate must be used. A convenient converter that also has native RS-422 support is a [[MaxLinear XR21B1420IL28-0A-EVB USB to RS-232/422/485 Evaluation Board]].

			Requests from the host seem to be a single byte, and the response is multi-byte with a checksum. For recognized commands the response's first byte is the request byte echo'd back, and it seems for unrecognized commands it has a default response. Here is a list of known commands:

			{\| class="wikitable"
			! Request
			! Response Length
			! Description
			\|-
			\| 0x02
			\| 7
			\| angle only (no full revolutions)
			\|-
			\| 0x1A
			\| 11
			\|-
			\| 0x2A
			\| 9
			\| same as 0xA2?
			\|-
			\| 0x32
			\| 9
			\| same as 0xA2?
			\|-
			\| 0x4A
			\| 11
			\|-
			\| 0x52
			\| 11
			\|-
			\| 0x62
			\| 9
			\|-
			\| 0x7A
			\| 3
			\|-
			\| 0x8A
			\| 6
			\| full revolutions only (no angle)
			\|-
			\| 0x92
			\| 4
			\|-
			\| 0xA2
			\| 9
			\|-
			\| 0xBA
			\| 7
			\|-
			\| 0xC2
			\| 11
			\|-
			\| 0xDA
			\| 11
			\|-
			\| 0xEA
			\| 9
			\|-
			\| 0xF2
			\| 3
			\|-
			\| 0xF4
			\| 3
			\|}

			Other possible commands are: <code>0x0A 0x22 0x3A 0x42 0x5A 0x6A 0x72 0x82 0x9A 0xAA 0xB2 0xCA 0xD2 0xE2 0xF3 0xF5-0xFF</code>

== Overview ==

Proprietary serial encoders made by Mitsubishi meant to work with their MELDAS CNC controllers. It uses 2.5 Mbaud RS-422 to communicate with the controller. The protocol has been partially reverse engineered, and is supported by Rene Hopf's STMBL servo drive.

== Specifications ==

[https://s3.amazonaws.com/Icarus/DOCUMENTS/Mitsubishi_Manuals_1004.pdf#page=195 Page 195] (III-58 in the PDF) of the BNP-C3000C(ENG) manual details the specifications for different variants.
