PORTER INSTALLATION AND OPERATIONS MANUAL
9
After installing the Porter, it must be configured to match the protocol for your
equipment. This consists of identifying the desired characteristics of your system and
sending the appropriate control bytes to the Porter. Serial Porter units also can be
configured through an interactive menu. The configuration may be stored in the Porter’s
non-volatile memory, whose contents will not be lost when removing the Porter’s power.
Configuration of Serial Units
The proper protocol, baud rate, number of stop / data bits, and parity information must be
set for each channel. This is done by using the interactive configuration menu, or by
sending the proper format commands to the Porter. The Porter factory set default is
9600 baud, 1 stop bit, no parity, 8 data bits, DTR/DSR handshaking. Refer to the format
command for further information.
The Serial Configuration Menu
You invoke the configuration menu – only on port 0 – by sending the command
S from a computer funning a communication program or a dumb terminal set at
9600,N,8,1. the configuration menu will then appear as shown in Table 1. is
factory set for the two characters ESC @ on a new unit, so initially use the string ESC @
S to get the menu.

Serial Configuration Menu Items
In the examples below, means “press the ENTER key”, not type the characters
. Output from the Porter is shown in Courier type. Input from the user to the
menu is shown in Underlined Courier type.
Change port protocol
This option allows the serial parameters for a port to be changed. The changeable items
are baud rate, parity, word length (data bits), stop bits, flow control, and DHS (direct
handshake). If the protocol for port 0 is changed, the menu will prompt you to change
your PC or terminal to the new baud rate and press to continue. Changes to
the port parameters are not made permanent until either the “Save new configuration”
option or the Keep command is used. You will be asked which port you want to change.
Enter the port number or R to change a range of ports.
