General Operation
Software and drivers for the ICRM are available at http://www.aarcomm.com/products/icrm-‐915/
1.
Determine the appropriate interface for the connection to your equipment (RS-‐232 or RS-‐485)
2.
Connect the interface wiring to your equipment or network
3.
Connect the power wires:
a.
“Power -‐“ to Ground
b.
“Power +” to 12V-‐24V
4.
The “POWER” LED will briefly turn on red, and then should turn green. Do not connect USB cable yet.
5.
Install the ICRM Windows USB drivers (ICRM_driver_32bit.exe or ICRM_driver_64bit.exe). Administrator
access will likely be necessary – Right click the application and select “Run as Administrator”.
6.
Connect to the CONFIG USB port of the ICRM. The STATUS LED should turn on green to indicate a USB
connection. This may take a minute as the computer initializes the driver.
7.
Run the ICRM Configuration wizard, “ICRM Config.exe” to configure the radio.
a.
Select a unique node number for the radio (see Local Node in Configuration section for
restrictions on node number).
b.
Determine a network key to use for all the radios in your network
c.
Select the Mode (Master, Slave, or Repeater). There must only be one Master in the network.
d.
Select a Data Rate for the radio. This is the over-‐the-‐air data rate that all radios will
communicate with each other. All radios must have the same data rate in order to
communicate. `
e.
Select the Interface (RS-‐232 or RS-‐485). For RS-‐422, select RS-‐485.
f.
Select the appropriate Protocol. See configuration wizard help for descriptions of the different
protocol options
g.
Recommended: Set the upstream node number to specify the node for a slave or repeater to
link to.
8.
Save settings and send to ICRM
9.
If the unit is a master, the “LINK” LED will turn green. If the unit is a slave or repeater and no master is
within range, the link LED will be red
10.
One interface LED – either the RS-‐232 or RS-‐485 – will turn on green
Notes:
−
At least two ICRM-‐915 radios (one master and one slave) must be configured and powered up to
achieve a link
−
One radio in a network must be configured as a master and all others as slaves/repeaters
−
Two master radios cannot communicate to each other
−
When a slave is properly configured, powered up, and within range of a matching master or repeater,
the “LINK” LED should be green indicating that the radios are now communicating
