Distribution of this memo is unlimited. Copyright Notice Copyright (C) GQ Electronics LLC (2012). All Rights Reserved. Abstract This document defines a GQ GMC Geiger Counter Communication Protocol to support communication between GMC Geiger Counter and a computer host via serial port. The protocol allows to send data request command from a computer host to a GQ GMC geiger counter. **************************Serial Port configuration************************** The serial port communication is based on a fixed baud rate. Baud: 57600Data bit: 8Parity: NoneStop bit: 1Control: None **************************Command format************************** A valid command start with ASCII '<' and ended with ASCII '>>'. Both command and parameters are in between '<' and '>>'. Command is a ASCII string. All parameters of command are true value in hexadecimal. Direction: All commands are initiated from computer(HOST). **************************Commands************************** 1. Get hardware model and version Command: <GETVER>> Return: total 14 bytes ASCII chars from GQ GMC unit. It includes 7 bytes hardware model and 7 bytes firmware version. e.g.: GMC-300Re 2.10 Firmware supported: GMC-280, GMC-300 Re.2.0x, Re.2.10 or later 2. Get current CPM value Command: <GETCPM>> Return: A 16 bit unsigned integer is returned. In total 2 bytes data return from GQ GMC unit. The first byte is MSB byte data and second byte is LSB byte data. e.g.: 00 1C the returned CPM is 28. Firmware supported: GMC-280, GMC-300 Re.2.0x, Re.2.10 or later 3. Turn on the GQ GMC heartbeat Note: This command enable the GQ GMC unit to send count per second data to host every second automatically. Command: <HEARTBEAT1>> Return: A 16 bit unsigned integer is returned every second automatically. Each data package consist of 2 bytes data from GQ GMC unit. The first byte is MSB byte data and second byte is LSB byte data. e.g.: 10 1C the returned 1 second count is 28. Only lowest 14 bits are used for the valid data bit. The highest bit 15 and bit 14 are reserved data bits. Firmware supported: GMC-280, GMC-300 Re.2.10 or later 4. Turn off the GQ GMC heartbeat Command: <HEARTBEAT0>> Return: None Firmware supported: Re.2.10 or later 5. Get battery voltage status Command: <GETVOLT>> Return: one byte voltage value of battery (X 10V) e.g.: return 62(hex) is 9.8V Firmware supported: GMC-280, GMC-300 Re.2.0x, Re.2.10 or later 6. Request history data from internal flash memory Command: <SPIR[A2][A1][A0][L1][L0]>> A2,A1,A0 are three bytes address data, from MSB to LSB. The L1,L0 are the data length requested. L1 is high byte of 16 bit integer and L0 is low byte. The length normally not exceed 4096 bytes in each request. Return: The history data in raw byte array. Comment: The minimum address is 0, and maximum address value is the size of the flash memory of the GQ GMC Geiger count. Check the user manual for particular model flash size. Firmware supported: GMC-300 Re.2.0x, Re.2.10 or later 7. Get configuration data Command: <GETCFG>> Return: The configuration data. Total 256 bytes will be returned. Firmware supported: GMC-280, GMC-300 Re.2.10 or later 8. Erase all configuration data Command: <ECFG>> Return: 0xAA Firmware supported: GMC-280, GMC-300 Re.2.10 or later 9. Write configuration data Command: <WCFG[A0][D0]>> A0 is the address and the D0 is the data byte(hex). Return: 0xAA Firmware supported: GMC-280, GMC-300 Re.2.10 or later 10. send a key Command: <key[D0]>> D0 is the key value from 0 to 3. It represents software key S1~S4. Return: none Firmware supported: GMC-280, GMC-300 Re.2.0x, Re.2.10 or later Note: for Re.2.11 or later, each key can be a ASCII string: <KEY0>>,<KEY1>>,<KEY2>>,<KEY3>> 11. get serial number Command: <GETSERIAL>> Return: serial number in 7 bytes. Firmware supported: GMC-280, GMC-300 Re.2.11 or later 12. Power OFF Command: <POWEROFF>> Return: none Firmware supported: GMC-280, GMC-300 Re.2.11 or later 13. Reload/Update/Refresh Configuration Command: <CFGUPDATE>> Return: 0xAA Firmware supported: GMC-280, GMC-300 Re.2.20 or later You can’t perform that action at this time.
