AUXILIARY SERIAL PORT

An electronic data processing serial port is available on the expansion
board. This auxiliary third serial communications port is represented by the
AUX submenu, in the first level SERIAL menu (see Figure 8-8 for layout).
The port address is a selectable parameter, under the AUX submenu.
The auxiliary serial port can be used as an RS-232 transmitter, 20 mA
current loop transmitter, or RS-485 transmitter (by adding a U7 integrated
chip). The AUX port can be configured for continuous stream or demand
print communications. The other menu selections are similar to the EDP port
selections, with the exception that the AUX port has a maximum baud rate
of 9600, rather than 19200, and is simplex output only.
