HMR2300
COMMAND INPUTS
A simple command set is used to communicate with the HMR2300. These commands can be automated; or typed in real-
time while running communication software programs, such a windows hyperterminal.
(1) All inputs must be followed by a <cr> carriage return, or Enter, key. Either upper or lower case letters may be used. The device ID
(dd) is a decimal number between 00 and 99. Device ID = 99 is a global address for all units.
(2) The “¬” symbol is a carriage return (hex 0D). The “_” sign is a space (hex 20). The output response will be delayed from the end of
the carriage return of the input string by 2 msec (typ.), unless the command sent as a global device ID = 99.

This error response indicates that this instruction requires
ASCII – Output Readings in BCD ASCII Format (Default)
Binary – Output Readings in Signed 16-bit Bianary
Format
P = Polled – Output a Single Sample (Default)
C = Continuous – Output Readings at Sample Rate
Escape Key – Stops Continuous Readings
Set Sample Rate to nnn Where:
Nnn = 10, 20, 25, 30, 40, 50, 60, 100, 123, or 154
Samples/sec (Default = 20)
S/R Mode: TN – ON = Auto S/R Pulses (Default)
*ddT Toggles Command (Default = On)
] Character – Single S/R: ]S -> SET = Set Pulse
Toggle Alternates Between Set and Reset Pulse
Read Device ID (Default = 00)
Set Device ID Where nn = 00 to 98
Set Baud Rate to 9600 bps (Default)
Set Baud Rate to 19,200 bps
Zero Reading Will Store and Use Current as a Negative
Offset so That the Output Reads Zero Field
*ddZR Toggles Command
The Average Reading for the Current Sample X(N) is:
Xavg=X(N)/2 + X(N-1)/4 + X(N-2)/8 + X(N-3)/16 + ...
*ddV Toggles Command
Turn the “Re-Enter” Error Response ON (*ddY) or OFF
(*ddN). OFF is Recommended for RS-485 (Default = ON)
Read Setup Parameters. Default: ASCII, POLLED, S/R
ON, ZERO OFF, AVG OFF, R ON, ID=00, 20 sps
Change All Command Parameter Settings to Factory
Default Values
Change All Command Parameter Settings to the Last
User Stored Values in the EEPROM
Output the HMR2300 Serial Number
Output the HMR2300 Software Version Number
Output the HMR2300 Hardware Version Number
Activate a Write Enable. This is required before
commands: Set Device ID, Baud Rate, and Store
Parameters.
This writes all parameter settings to EEPROM. These
values will be automatically restored upon power-up.
A command was not entered properly or 10 characters
were typed after an asterisk (*) and before a <cr>.
a write enable command immediately before it.
TF – OFF = Manual S/R Pulses
(8 bits, no parity, 1 stop bit)
