t
RX-TXD
TBD us
Time from last byte is received from the air until first character is sent
on the UART
t
TXD
Min TBD us
t
TXD
= # bytes received x 621 us/char (10 bits at 19.2 kBd + 100 us
delay per character)
t
TXD-IDLE
TBD ms
Time from last character is sent on the UART until module is in IDLE
mode (ready for RXD and RX)
T
RXD-CTS
TBD us
Time from last character is received by the UART (including any
timeout) until CTS is activated
t
RXD-TX
TBD ms
Time from last character is received by the UART (including any
timeout) until the module sends the first byte on the air.
T

CONFIG-
PROMPT
TBD ms
Time from 00h / CONFIG pin is set low until prompt (“>”)
t
C#-CONFIG
TBD ms
Delay after channel-byte is sent until prompt (“>”). (For other
commands like ’M’, ’T’ there is no delay but immediate prompt)
t
MEMORY-
CONFIG
TBD ms
In this period the internal flash is programmed.
Do not reset, turn the
module off, or allow any power supply dips in this period as it may
cause permanent error in the Flash configuration memory. After 0xFF
the host should wait for the ‘>’ prompt before any further action is
done to ensure correct re-configuration.

TBD ms
t
TX
Min TBD ms
t
TX
= # bytes to send x 1.67 ms/byte (at 4.8 kbit/s). Add 13 overhead
bytes if addressing and CRC is not used. Add additionally 2 extra
bytes for addressing and 2 extra bytes for CRC if enabled.
