Note: We recommend that for optimal performance, you use only shielded modular
cable between the Pinnacle Plus+ unit's Standard Serial port and your host
computer.
Transmission Parameters
The communications capability of the Standard Serial port is limited to the following
parameters.
Note: These transmission parameters do not apply for units with AE Bus cards
installed. If your unit has an AE Bus card installed, see the AE Bus section of
this manual for more information on transmission parameters.
• RS-232 protocol
• Baud rate of 19.2 kbps
• Pinnacle Plus+ unit address of 1
• Odd parity
• 1 start bit, 8 data bits, one stop bit
• Low-order bytes are transmitted before high-order bytes
Please note that the time-out period for the Pinnacle Plus+ is factory set at 0.02 s (that
is, no more than 20 ms can elapse between bytes or the unit will reset and begin
looking for a new message packet). This can be changed using command 40 or from
the active front panel.
