PTR for VHF-4000 and VDL-2000 Data Radios Appendix C - VDL Mode 2 Operation The BFR test message is a VDL Mode 2 message containing 249 application bytes. The message will also contain 6 Reed Solomon check bytes for a total of 255 bytes.
PTR for VHF-4000 and VDL-2000 Data Radios For any transmit or receive tests in VDL Mode 2, the unit must first be placed in VDL Mode 2: 1) Ground the Voice/Data Discrete 2) Transmit 0008001D#, 8000235E# on CMU Port A input. This message must be sent at a rate of at least once a second to maintain VDL Mode 2 operation. 3) Monitor CMU output bus for a label 270 message. Bits 20 – 24 show the mode status of the radio, the status should be 0010. 4) Transmit 47000315# (ALO) on CMU Port A input.
