Appendix F. Extended ASCII Command Set
F.3.9 Set Self-timed Transmission Preamble Length
Syntax:
TPR=S/L
Access level: USER
TX320 State: Disabled
Set the preamble type for timed transmissions. Valid values are S or L (Short
or Long). This setting only applies for 100 bps timed transmissions on
channels 1 – 200. All 300 and 1200 bps transmissions us short preamble. All
100 bps transmissions on channels above 200 use long preamble.
F.3.10 Set Self-Timed Transmission Interleaver Mode
Syntax:
TIL =S/L/N
Access level: USER
TX320 State: Disabled
Set the timed transmission interleaver type. Valid values are S, L, or N (Short,
Long or None). This setting only applies for HDR timed transmissions, i.e.
300 or 1200 bps.
F.3.11 Set Self-Timed Transmission Data Format
Syntax:
TDF =A/P/B
Access level: USER
TX320 State: Disabled
This command sets the timed transmission format to ASCII, pseudo binary or
binary. Valid values are A, P or B. This parameter is used to determine the
flag word in 300 and 1200 bps transmissions.
Note: It is the responsibility of the host to ensure the data provided for
transmission is in the proper format. ASCII data can not be transmitted when
pseudo binary format is selected. Pseudo binary can be transmitted with ASCII
format has been selected.
F.3.12 Set Random Transmission Channel Number
Syntax:
RCH=ccc
Access level: USER
TX320 State: Disabled
This command sets the channel number for random transmissions. ccc is the
channel number and has a valid range of 0 – 266 for bit rates of 100 and 300
bps and a range of 0 – 133 for a bit rate of 1200 bps.
