5 General Information
1.2 Physical Interfaces
RS232 (Serial COM port): 57600 baud (8Bits, no Parity, 1 Stop). Requires 0-Modem
(crossover) cable, only TX, RX and GND pins are relevant.
USB: Will be recognized as virtual COM port (requires Quinta USB
driver), settings like above
TCP/IP (factory default): Telnet: Port 23
Default IP: 192.168.1.55
DHCP: active
1.3 General Operation Rules
Data format and communication concept
Please be sure to read this chapter carefully as it contains important information on
the serial communication used in the Quinta system.
Communication direction
Each command structure has a specific communication direction in which it is used in
the Quinta system. This direction is shown at the beginning of each table that breaks
down the commands in their structure. In order to provide a better overview in this
document, individual communication paths are assigned a specific color.
orange: Controller -> CU (wired communication)
blue: Controller -> CU -> MU (wired and wireless communication)
green: CU -> Controller (wired communication)
yellow: MU -> CU -> Controller (wired and wireless communication)
All communication uses ASCII characters
This means all received and sent information has to be coded using ASCII characters in
strings. Different parameters are separated by ASCII-blank characters (0x20).
Communication is built up in the following way:
(1) Commands use ASCII characters which are case sensitive. The single characters
are separated by ASCII-blank characters.
(2) Numeric values (e.g. volume-value) are also realized with ASCII characters which
in turn have to be interpreted as hexadecimal numbers, so that two ASCII-
characters represent a one-byte hexadecimal number.
The maximum number range depends on the command.
(3) In certain instances hexadecimal numbers following the command are
interpreted as a combined status information. In this case the hexadecimal
number has to be converted into the binary number representation. Individual
bits within this number represent certain status flags.
(4) Some information in the strings has to be interpreted as a usual string of ASCII-
characters which for example show a password.
So you always have to take a closer look at the documentation of the commands.
(5) Each command must end with an ASCII carriage return <CR>.
