Property Description
Receive timeout Maximum time (in milliseconds) that APIcom waits for a response from the
instrument after a command is sent. The instrument’s response time varies
depending on a number of factors, including its operating firmware, the
connection type, the baud rate, etc.
Transmit delay Most of the instruments do not use any conventional RS-232 handshaking, such
as RTS/CTS or XON/XOFF. Newer instruments do support XON/XOFF
handshaking, which APIcom also supports (see site configuration). This transmit
delay property inserts a brief delay between each line of iDAS or sequence
configuration information that APIcom sends to the instrument, in lieu of
conventional handshaking. This transmit delay prevents APIcom from
overflowing the receive buffers of slower instruments, which will cause them to
reject the iDAS or sequence configuration.
