Jumper Descriptions:
J1: Sets Port 1 Transmit data output to either FSK (FET transistor switch ON/OFF) center pin to pin
1, or TTL drive (0 to +3.3 V) center pin to pin 2.
Default: FSK
J2: Sets Port 1 Receive input impedance. Open = 10 k, closed = 620 .
Default: open
J3: Sets Port 2 Transmit data output to either FSK (FET transistor switch ON/OFF) center pin to pin
1, or TTL drive (0 to +3.3 V) center pin to pin 2.
Default: open
J4: Sets Port 2 receive input impedance. Open = 10 k, closed = 620 .
Default: open
J5: Port 2 PTT Watchdog. When open, the watchdog is enabled. PTT will discontinue after about 2
min of continuous transmit. When closed, the watchdog is disabled, and PTT will remain active as
long as commanded.
Default: open (enabled)
J6: Port 1 PTT Watchdog. When open, the watchdog is enabled. PTT will discontinue after about 2
min of continuous transmit. When closed, the watchdog is disabled, and PTT will remain active as
long as commanded.
Default: open (enabled)
