GPS Receiver Status & Environment
- Continued
Longitude:
Displays current latitude position of CTM gathered from the GPS receiver. You must have visability of at least 4 satel-
lites before this field will show actual coordinates.
Altitude:
Displays current altitude of CTM. You will need more than 3 satellites before this field will show the actual elevation. Units
of measurement can be changed from the default Metric units to standard in the General System Settings page.
Time Zone:
Displays current time zone in relation to GMT. User can change offset in General System Settings page.
CTM Slave:
Displays number of slave CTM’s connected to the CTM-1M. By default this field will show CTM Slave Units Not En-
abled.
Temperature:
Displays current temperature inside the CTM case. Normal operating temperatures may vary depending on environ-
ment and installation. Temperature display units are adjustable from Celsius (default), to Fahrenheit in the General System Settings
page.
Primary Volts:
Displays current voltage on primary power port. Normal operating voltage is approximately 24VDC. In the event that
the port has been shorted out, this field will display an OVER CURRENT alarm. The CTM will automatically switch to the secondary
power port until the short has been removed.
Secondary Volts:
Displays current voltage on secondary power port. Normal operating voltage is approximately 24VDC. In the
event that the port has been shorted out, this field will display an OVER CURRENT alarm.
Logic Volts:
Displays current voltage powering memory and processor circuits within the CTM, and should read approximately
5VDC.
CTM Radio Setup
CTM Master/Slave Buttons:
When enabled this page will display a button to switch between the Master and Slave radio pages.
The same information will be recorded and displayed for slave when connected via the Slave port.
CTM Power & Temperature:
Here you will find the current voltage readings for both the primary and secondary power supplies as
well as the logic power for the onboard electronics.
Primary Volts:
Displays current voltage on primary power port. Normal operating voltage is approximately 24VDC. In the event that
the port has been shorted out, this field will display an OVER CURRENT alarm. The CTM will automatically switch to the secondary
power port until the short has been removed.
Secondary Volts:
Displays current voltage on secondary power port. Normal operating voltage is approximately 24VDC. In the
event that the port has been shorted out, this field will display an OVER CURRENT alarm.
Logic Volts:
Displays current voltage powering memory and processor circuits within the CTM, and should read approximately
5VDC
Temperature:
Displays current temperature inside the CTM case. Normal operating temperatures may vary depending on envi-
ronment and installation. User can change temperature display units from Celsius (default), to Fahrenheit in the General System
Settings page.
CTM Radio Setup/Status:
Here you will make all of the radio port settings and can enter the radio name for each port.
Pwr (W): This column will display the current power draw in Watts from each radio port.
Reset:
A green check in this box will cycle the power on the corresponding port. Power will be interrupted for 3 seconds before it
is restored automatically. To reset any port simply check the box and press the Apply Radio Settings button.
Port ON:
A green check in this box will send 24VDC to pins 4, 5, 7 and 8 to the corresponding port number. Only the top RJ45 port
will be powered, with the lower port carrying Ethernet from a switch or router. To change the power status of each port, check or
uncheck the box next to the port number you wish to change. When finished making changes, press the Apply Radio Settings but-
ton at the bottom of the window to save changes. The port will change the power status only after you have saved your changes.
Sync ON:
A green check in this box will send a 1 pulse per second sync signal to the radio plugged into the corresponding port.
This extremely fast interruption in power is picked up by the radios as the sync over power signal.
Radio Name:
Here you can enter a name that will be associated to each port. When finished making changes, press the Apply
Radio Settings button at the bottom of the window to save changes.
