Owner`s manual

Configuration is done via verbose (menu-driven) mode

or non-verbose mode where a character string is sent to

configure the desired I/O module. You can also

configure the system clock of the M Series unit from the

V71 in the verbose mode. The supported configuration

and data commands for a specific I/O module are

described in the documentation for that module. All I/O

modules can be programmed

to communicate in immediate reporting mode where

data is sent to the host computer as it is received.

An I/O module must be in command mode before the

V71 can access the verbose (menu-driven) configuration

mode for that I/O module, issue non-verbose

configuration commands, or issue data commands. The

main board must be in command mode to configure the

system clock. An I/O module or the main board is

placed into command mode by sending a select

sequence to the V71 from the host computer. The

select sequence consists of the port select code, the

desired module number (0 to 16), and a terminating

character of Carriage Return (0D Hex) or Line Feed (0A

Hex). The module number is "0" to place the M Series

main board into command mode. For example, to place

the fourth I/O module into command mode, send

$BT4<cr> from the host computer, where <cr> is

Carriage Return and $BT is the default port select code.

After you have configured and/or issued any necessary

data commands to the desired I/O module or main

board, you would typically disconnect from the I/O

module/main board by sending the port select code

followed by Carriage Return.

NOTE: If you attempt to place an I/O module or the

main board into command mode and the I/O

module/main board is currently selected by another host

module or the service port, you will receive a Busy!
