13 Analogue RSSI O Synthesised average of RSSI (20dB/V absolute reference TBD)
[can also be used as a general purpose analogue output]
0-2.5v
14 GND N/A
15 Tx_LED O Tx activity (Active Low) 3.3V TTL
16 Analogue Input I General purpose analogue input. 66k input resistance. 0-6v
17 Sync_LED O Masters: 100ms pulse when user data received (Active Low)
Remotes/Bridges: pulsed every 1500ms for 100ms when master acquired,
additional 100ms pulse when user data received (Active Low)
3.3V TTL
18 TxD_PORT1_LED O Pulsed for 100ms for any TxD activity for Port 1 [Port B on K-Series] (Active
Low)
3.3V TTL
19 RxD_PORT1_LED O Pulsed for 100ms for any RxD activity for Port 1 [Port B on K-Series] (Active
Low)
3.3V TTL
20 TxD_PORT2_LED O Pulsed for 100ms for any TxD activity for Port 2 [Port A on K-Series] (Active
Low)
3.3V TTL
21 RxD_PORT2_LED O Pulsed for 100ms for any RxD activity Port 2 [Port A on K-Series] (Active
Low)
3.3V TTL
22 Pwr_LED O DC power OK (Active Low) 3.3V TTL
23 nFACT/TEST-
MODE
I Reset factory defaults (Active Low on power-up) or
Test Mode (Active High on power-up) or
Neither (tri-state)
If this pin is pulled high once the unit is in a fatal error state the fatall error
condition will be indicated on the LED status lines.
3.3V TTL
24 PTT I Keys the radio at maximum TX/RX duty cycle using the current programmed
channel selection and output power (Active Low).
Note that while a radio is in this mode no data can be passed, the RSSI
indication on other units will not respond to the radio being PTT keyed and it
may block other systems.
3.3V TTL
25 TxInhibit I Tx inhibit for hot standby operation (Active High) 3.3V TTL
26 nSHUTDOWN_IN I Power down entire module (Active Low) 3.3V TTL
27 TxSync Input I Tx Sync input 3.3V TTL
