HARNESS AS-WIRING 2465379 - Caterpillar

Table 12
Obtain the manual from the radio manufacturer.        
Verify that the radio communicates Compact Measurement Records (CMR)s over RS232. Verify that the settings can be changed to match the Display.        
Review the power requirements for the radio. Review any special requirements. machine power may run to 28VDC        
Validate the radio settings in order to communicate with base radio.     Radio channel        
Over-the-air data rate    
Find pin out information for manufauturer's radio.        
Find drawing or pin out for correct machine. Refer to ""Radio Pin-Out Tables and Schematics"" for additional information.        
Create a simple schematic from the information that was collected in order to show which pin on the radio maps to the pin on machine connector.        
Create the harness based from simple schematic.        
Install harness on machine. Verify the power to the radio when system is turned on.        
Verify that AccuGrade System is receiving CMR's from Base Station.        Troubleshooting
No Power To Radio
Verify connections to power and ground pins
Verify input power required for radio
If converter has been added, ensure +PWR and Ground from AccuGrade connector are connected to converter, and that +PWR and Ground from converter are connected to radio
No Communication Through Radio
Verify that the radio is a Data Terminal Equipment (DTE) device.
If the radio is a Data Communications Equipment (DCE) device, modify the TX and the RX connections as shown in Illustration 148.

Note: It is critical to follow the documentation from radio manufacturer in order to ensure the proper handshake and/or other communications startup procedure is properly executed. Additionally, Customer Supplied Radios may require additional pins to be grounded or to be tied to voltage, and these will also be identified in the manufacturer's documentation.Radio Pin-Out Tables and Schematics
