10. 6NV (V.35) Interface
Connect a 6NV interface to each of the
FireBerd’s V.35 cables. And set the FireBerd as
follows:
• Synth freq. 64.0kHz
• Int. setup 449V35
• Type V35
• Emulate DTE
• Char format
• Data 8
• Parity none
• Stop 1
Configure the module to N=1 and map FOCUS to
allow communications between modules.
The Receiver section of the FireBerd should show
all three LEDs on (MK=yellow, SP=Yellow,
SYNC=Green & SYNC Lost indicator=OFF).
The error count should be zero.
