Table 4-1. 58502A Command
Parameters Description
INPUT Subsystem (Continued)
append 0 or OFF, or Enables or disables the automatic input switching feature. 0 or
1 or ON OFF disables it while 1 or ON enables it. This setting is stored
returns 0 or 1 in non-volatile memory.
Query.
A or B Selects the default input channel (or port) to be used at
powerup. This setting has no impact on auto-switching and
does not affect the current input channel selection. This setting
is stored in non-volatile memory.
returns A or B Query.
OUTPut:QUEStionable Subsystem
returns binary Provides status on each output in a single packed integer.
weighted decimal Each bit is associated with an output channel. The least
significant bit = output 1, next bit = output 2, and so on. If bit is
0, output signal is present. Hence value of 0 indicates that all
outputs are outputting the source signal. If there was no output
from outputs 2 and 3, the response would be:
6 (1*0 + 2*1 + 4*1 + 8*0 + ... = 6)
returns array of Provides status on each output (lowest numbered output to
Boolean highest). 0 = signal at output, 1 = no signal at output. Same
result as PACKed? (see prior command), but information on
each output is provided with separate value. If outputs 3 and 5
were not outputting the source signal, the response would be:
0,0,1,0,1,0,0,0,0,0,0,0
ROSCillator Subsystem (USED WITH OPTION 010 ONLY)
0 or 1 Reports if internal oscillator is warmed up.
0 = not warm.
1 = warm.
SYSTem Subsystem
Node Only
0 or 1 Sets duplex. (0 = echo Off, 1 = echo On).
Node Only. There is a single setting of commands under this
node for both transmit and receive. Default values are in italics.
<numeric> Sets the BAUD rate (1200, 2400, 9600, 19200).
7 or 8 Returns Data Bits set by PARity (7 for odd/even, 8 for none).
XON | NONE Sets flow control. (On or None).
Node Only.
EVEN | ODD | Sets parity. (Odd, Even, or None).
NONE
returns integer, First parameter is error number, quoted string is error
quoted string description.
