Generated from FlexLib v4.2.18
Transmit interlock configuration
Commands follow the FlexRadio TCP wire protocol:
C[D]<seq_number>|<command> [sub-command] [parameters]
Where:
-
C= Command prefix -
D= Optional debug flag -
<seq_number>= Sequence number for command tracking -
<command>= Primary command word -
[sub-command]= Optional sub-command -
[parameters]= Command-specific parameters
Responses follow the format:
R<seq_number>|<result_code>|<data>|[debug_info]
Where:
-
R= Response prefix -
<seq_number>= Matching sequence number from command -
<result_code>= Result code (0= success, non-zero = error) -
<data>= Command-specific response data -
[debug_info]= Optional debug information

Syntax:
C<seq>|interlock <parameter>=<value>
| Parameter | Description |
|---|---|
timeout |
The timeout period for the transmitter to be keyed continuously, in milliseconds. If set to 120000, the transmitter can be keyed for 2 minutes continuously before begin unkeyed automatically. |
rca_txreq_enable |
Enables or disables the Transmit Request functionality via the Accessory input on the back panel of the radio. |
acc_txreq_enable |
Enables or disables the Transmit Request (TX REQ) RCA input on the back panel of the radio. |
rca_txreq_polarity |
The polartiy of the Transmit Request (TX REQ) RCA input on the back panel of the radio. When true, TX REQ is active high. When false, TX REQ is active low. The RCA port must be enabled by the TXReqRCAEnabled property. |
acc_txreq_polarity |
The polartiy of the Transmit Request input via the Accessory port on the back panel of the radio. When true, TX REQ is active high. When false, TX REQ is active low. TX REQ functionality via the Accessory port must be enabled by the TXReqACCEnabled property. |
tx_delay |
The delay duration between keying the radio and transmit in milliseconds |
tx1_enabled |
Enables the TX1 Transmit Relay RCA output port on the back panel of the radio |
tx2_enabled |
Enables the TX2 Transmit Relay RCA output port on the back panel of the radio |
tx3_enabled |
Enables the TX3 Transmit Relay RCA output port on the back panel of the radio |
acc_tx_enabled |
Enables the Transmit Relay output via the Accessory port on the back panel of the radio |
tx1_delay |
The delay in milliseconds (ms) for the TX1 RCA output relay. This port must be enabled by setting the TX1Enabled property |
tx2_delay |
The delay in milliseconds (ms) for the TX2 RCA output relay. This port must be enabled by setting the TX2Enabled property |
tx3_delay |
The delay in milliseconds (ms) for the TX3 RCA output relay. This port must be enabled by setting the TX3Enabled property |
acc_tx_delay |
The delay in milliseconds (ms) for the Transmit Relay output pin via the Accessory port on the back panel of the radio. This pin must be enabled by setting the TXACCEnabled property |
