Condec DLR3110 - Manual (Page 39)

Serial Input/Output 35
Data entry code = < E > character (45H). Commands with data sent from the host to be entered into
the DLR.
Examples:
• Setup data
• Calibration data
6.3.3 Basic RS485 Commands
Unit address 01 is used in Table 6-2 for illustration.
NOTE: A more extensive document detailing the full RS485 command codes is available upon request from CONDEC.

6.4 Continuous Simplex Output (Compressed Format)
The pressure value that is compressed consists of the polarity and pressure value including the . The data in
the compress mode is based on the six-digit display plus a when required. To enable see Section 5.13.1 on
page 24.
The data output format of the serial transmission is of the general form shown below:
<-/D06>
Where:
<-/D06> = The minus character if present and the most significant digit if positive.
-- = The pressure digits.
-- = Rest of data not effected (for example: units, mode).
The floating is added to the string when required. Therefore, the string is one character longer
when a is added.
Examples:
100.0-- <1> <0> <0> <0> ---
123456-- <1> <2> <3> <4> <5> <6> ---
- 345.6 -- <-> <3> <4> <5> <6> ---
6.5 Serial Output Wiring and Hardware Configuration
This section details the wiring configuration for serial transmission to a remote device such as a printer. All direct
wiring on terminal block (TB3) and hardware settings are well marked and can be located at the rear portion of
the CPU board assembly.
