Appendix E – Serial command protocol

To serially command the Orion LC, following parameters are used:

For communication please set up the format of the serial data

communication to:

115,2K,8,1,NO (115,2 KBAUD, 8 Data bit, 1 Stop bit, NO parity)

Structure of serial command

<STX>, <command byte (CMD)>, [data bytes (D0..DN)], <ETX>

[ ] = optional elements

Parameter description

Command byte in the range of 0x40...0x6F (see Appendix D)

Data Bytes a) Binary data: in order to prevent that, during the

transmission of binary data, control statements or control

commands are transferred, the data are divided into low-

nibble and high-nibble. The data are distributed to the low-

nibbles of two bytes and provided with an offset by 0x60 e.g.

0x1F => 0x61 + 0x6F

b) 7bit-data (0x0...0x7F) are provided with an offset by

0x80, e.g. 0000011 => 0x83

c) ASCII-data => 0x20… 0x7E are unencrypted transmitted

(Special-)Character ACK 0x06 ETX 0x03

NAK 0x15 CR 0x0D

STX 0x02 ESC 0x1B

Appendix F – Rack mount

Up to 4 Orion LC units can be mounted on the RM-BR3DV4 rackmount

shelf. The units can be orientated on the shelf with either the front or rear

panel to the front of the shelf.

Line up the two

threaded holes in the

bottom of the Orion

LC unit with the

mounting holes on

the shelf identified in

RED. Please use

proper strain relief

for the CAT5 cables

connected to the

Orion LC
