RS-232, AE BUS HOST PORT CABLING REQUIREMENTS

The communications capability of the serial AE Bus Host port is limited to the following parameters:

RS-232 protocol

Baud rate of 19.2 kbps

Apex generator unit address of 1

Odd parity

One start bit, eight data bits, one stop bit

Low-order bytes are transmitted before high-order bytes.

The time-out period for the Apex generator is factory set at 0.02 s (that is, no more than 0.02 s can elapse between bytes, or the unit will reset and begin looking for a new message packet). This value can be changed using command 40.
