NONE No communications
disP Sends image data from the display without conversion to ASCII.
Cont Sends ASCII form of display data every time display is updated.
POLL Controlled by computer or PLC as host. Host sends command via
RS232/485 and instrument responds as requested.
A.buS A special communications mode used with Windows compatible
optional PC download software. Refer to the user manual supplied
with this optional software.
Addr 0 to 31 Set unit address for polled ( POLL ) mode (0 to 31)) - seen only with serial
output option. Refer to the separate “PM4 Panel Meter Optional Output
Addendum” booklet supplied when this option is fitted. Allows several units to
operate on the same RS485 interface reporting on different areas etc. The
host computer or PLC may poll each unit in turn supplying the appropriate
address. The unit address ranges from 0 to 31 (DEC) but is offset by 32 (DEC)
to avoid clashing with ASCII special function characters (such as <STX> and
<CR>). Therefore 32 (DEC) or 20 (HEX) or ! (ASCII) is address 0, 42 (DEC) or
2A (HEX) or * (ASCII) addresses unit 10.
Returning to normal measure mode
When the calibration has been completed it is advisable to return the instrument to the normal mode
(where calibration functions cannot be tampered with). To return to normal mode, turn off power to the
instrument, wait a few seconds and then restore power.
