16 X26 Serial Connection DATA Terminal 2 /
FSK Test
16.1 Set transceiver to F1D (FSK) modulation
(default values).
Set X26.37 (PTT1_V28) to +12 VDC.
Apply +12.0 VDC to X26.33 (TXD2).
By using the digital multimeter, verify DC volt-
age at X26.19.
> +3.0 VDC
Apply -12.0 VDC to X26.33 (TXD2).
Verify DC voltage at X26.19. < -3.0 VDC
Release X26.37 (PTT1_V28) to open.
