Crestron QM-RMCRX QuickMedia Receiver/Processor
NET (Cresnet)
This yellow LED illuminates when the QM-RMCRX communicates with
Cresnet devices on the network, and also indicates that the SIMPL Windows
program currently loaded has a network device defined at the same network ID
as the QM-RMCRX.
Reset Buttons
Two buttons are provided on the front panel of the QM-RMCRX. Refer to the
following descriptions.
HW-R
Pressing this button initiates system hardware reset. (Same effect as
disconnecting and reconnecting power.)
SW-R
Pressing this button in combination with the HW-R button performs a system
restart without loading the program (refer to “Troubleshooting
Communications” on page 22). Press HW-R momentarily while pressing and
holding SW-R to reboot.
Pressing SW-R alone while the system is running restarts the program.
Serial console connection may be established if SW-R button is pressed and
held about five to seven seconds during power up (wait for Viewport to display
some information), or if pressed and held at the same time HW-R is
momentarily pressed. The serial console mode is also established if the
processor is configured as a master, but has no program loaded. In this way, the
console mode is enabled out-of-the-box and the user does not have to perform
any special steps to initially configure the processor.
NOTE: The COM B LED will flash when in the console mode.
To terminate the console mode, press the HW-R button or cycle the power.
NOTE: Pressing <F10> (Program Reset) in Viewport may cause errors if both
the program and the console mode are using the same COM port.
Memory
The QM-RMCRX has 36 MB of built-in memory (non-volatile and volatile).
The total of 36 MB is specified as follows: 4 MB flash (non-volatile), 32 MB
SDRAM (volatile), and 256 KB NVRAM (battery backed up). Flash memory
contains the file system inside the 2-Series control engine. Non-volatile memory
contains information that is retained after the loss of electrical power. Volatile
memory is lost after a power failure. Refer to the following lists for a breakdown
of memory usage for program-related information stored in the unit.
