# = Device address from 1 to 9, A to V, or 0 for common address
H = Command letter
S = Sign of value, space (or +) for positive, - for negative value
D = Digit from 0 to 9
* = Decimal point placement and must always be included
A = Alarm and overload character code, A to H
<CR> = Carriage return character
The following table lists the Alarm and Overload characters.

If the DPM is in the Continuous mode, it must be put into the Command mode by sending
*#A1 prior to sending the remote display value.
The Remote Display value remains on the display until one of the following occurrences:
a. The command *#C4 is sent removing the Remote Display value and returning to the
normal readings without resetting the DPM.
b. The command *#C0 is sent causing a Cold Reset of the DPM.
c. The command *#C1 is sent causing a Warm Reset of the DPM.
d. Front panel pushbuttons RESET and MENU are simultaneously pushed to cause a Cold
Reset of the DPM.
Notes: After the Remote Display value is entered, the DPM can be put back in the Continuous
mode with the command *#A0 without disturbing the display’s value. DPM must be in the
Command mode for a., b., or c. above. It may be put into the Command mode while displaying
a remote display value with the *1A1 command without affecting the display.
If PEAK (manual or external) or ALARM VIEW (manual) is activated while the remote value is
being displayed, the peak or alarm value is displayed and cannot be removed except by Remote
Display Reset (a., b., or c. above in Command mode) or by manual RESET. If a Remote Display
value is sent while in PEAK or ALARM VIEW, it is ignored, but when PEAK or ALARM VIEW is
turned off, the Remote Display value comes on.
MODE 2: DPM with Signal Conditioner Card and in Remote Display Mode
SETUP (left digit) = 1 Remote Display mode
The baud rate must be set the same as the source which may be a PC Controller or another
DPM. The format is the Slave Format. This is the same as MODE 1 above but without the
Command Identifier “*”, the address #, and the Command letter “H”. This is the same format
that data is transmitted from a DPM in the Continuous mode. The string of characters must be
exactly 8 characters plus the CR in length.
SDDDDD.A <CR>
No commands can be received in this mode but the front panel MENU can be accessed. Any
transmissions received other than properly formatted data will result in a meaningless display.
Alarm setpoints, Peak readings and external control functions are disabled while the Remote
Display value is being displayed. When the DPM is Reset, it displays RESET continuously until
data is received.
DATA FORMAT
*1HSDDDDD.A
S = Sign, either blank (for +) or -
D = Digit from 0 to 9, five digits total. Always include a decimal point even at the end.
A = Alarm character as defined in ???.
8.5 COMMAND MODE FOR REMOTE DISPLAY OPERATION OF COUNTER / TIMER
The Counter has 13 Display Modes (0-12). Modes 0-5 are normal measurement modes. Modes
6-12 are dedicated to Remote Display without making any normal readings. In any of the 13
modes, remote display data may be received via RS-232 or RS-485 and be displayed. The
remote data requirements and the Remote Display capabilities vary for the different display
modes and selected Input Functions. The mode is selected by Menu item “ConFiG” “Digit 3”
