| General Specifications |
| Programming code format |
| |
7-bit ISO code (ASCII) characters. Upper or lower case characters. |
|
| Input separator |
| |
The counter accepts the following separators: ETX, ETB, CR, LF, " "(space), "," (comma), ":" (colon) ";" (semicolon) |
|
| Output data separator |
| |
Default separator at power-on is LF. The separator can be programmed to any non-printable ASCII-code with decimal equivalent 0-31, except 27 (ESC). The combination 13 + 10 (CR + LF) can be programmed. The EOI line can be programmed to be active together with the last output byte sent. |
|
| Output format |
| Normal: |
20 characters plus separators(s) 7 characters alphabetic header plus 13 characters numeric value |
| Short output: |
Alphabetic header and leading zeroes are omitted. |
|
| High-speed dump |
| |
The contents of internal registers are transferred to the controller, without being processed by the counter. The processing must be done in the controller instead. |
| Max output rate: |
approx 100 readings/s |
| Output format: |
A 2 character header, followed by 12 Hex-digits plus separator(s) |
|
| Max data output rate |
| Normal mode: |
Approx 5 readings/s |
| High-speed dump: |
Approx 100 readings/s |
|
| Output time for measuring data |
| Normal mode: |
Approx 15 rms (20 bytes) |
| High speed mode: |
Approx 6 ms (15 bytes) |
|
| Response time for addressing |
|
| Response time for trigger command (GET) |
|
| Typical read time for programming data |
