If the product is supplied by a battery with an energy-saver mechanism, this energy-
saver mechanism is suspended during the ESA session until the product receives a
PRC command.
How to Use the ESA Command
The host must send the ESA command repeatedly with each RS-232 parameter in the
order shown in Table 4-16 until the 1555 responds with a low-level ACK character,
unless the RS-232 communication parameters in the product are already known. In
that case, the host can issue an ESA with those known communication parameters.
Two parameters must be set in the ESA command:
•
Hardware handshaking protocol if applicable (default: no CTS/RTS); and
•
Desired baud rate for communication (e.g., 57600 bauds).
