3.11.2 AntDL Switch Command (19 54)
This command message accepts only one one-byte parameter, which is:
30: Switch the RF output to the antenna
31: Switch the RF output to the dummy load
The antenna/dummy-load switch can be in one of the following states (as displayed in the AntDL menu on an
attached RCP-2001): “Disc”, “Antenna”, “Dummy Load”, “Switching”, “SwPwrFail”, or “?ADL”. The last is
used if a problem in the hardware prevents the status of the switch from being determined.
3.12 RC Panel Message (1C)
This message is not answered by the SSPA, but rather by a connected RCP-2001 Remote Control Panel. If
the RCP-2001 is not present, or is not powered, this message will receive NO RESPONSE.
B
RCP_STATUS
: 30 = RCP-2001 is OK, Link with SSPA is OK.
38 = RCP-2001 ROM failure
39 = RCP-2001 RAM failure
3B = RCP-2001 Invalid Interrupt
3C = RCP-2001 Stack Overflow
3D = RCP-2001 Illegal Opcode
4F = RCP-2001 Cannot communicate with SSPA
6F = RCP-2001 Front Panel failure
72 = RCP-2001 Parallel I/O failure
77 = RCP-2001 Spurious Reset
78 = RCP-2001 EEPROM data corrupt
79 = RCP-2001 EEPROM data write failure
To reset RCP reported errors, send message 1C 0A. No response will be generated.
3.13 Unit Status (20)
This message requests the major information from the unit in the form of bit flags. The data is returned as
three bytes in the message body. The most significant two bits in each byte will be 0 and 1 respectively. The
remaining six bits in each of the two bytes will contain the data.

Each bit is a flag indicating the following conditions, if set:
b
RF_OUTPUT_STATUS_OPERATING
= RF is ON.
b
MUTE_CONTROL_MUTED
= RF is OFF because the MUTE control (Serial I/O, Parallel I/O
or Local) has been asserted.
B
LSUM_ANY_WARNING
= There is an active Latched WARNING.
b
LSUM_ANY_FAULT
= There is an active Latched FAULT.
b
OTHER_UNIT_FAULTED
= Either the other unit is reporting a fault, or there is no
communication with the other unit, in a 1:1 system.
b
RMODE_AUTO_OR_SPARE
= The redundancy mode is set for AUTO or SPARE.
b
THIS_UNIT_ONLINE
= This unit is on line (in a 1:1 system), or there is a problem
reading the switch position, or the switch is changing state.
b
THIS_UNIT_STANDBY
= This unit is in standby (in a 1:1 system), or there is a problem
reading the switch position, or the switch is changing state.
