Table 8. Device Addresses

Valid Device Addresses

Length 1 to 3 characters

Range 1 to 255

When using the KP-10 external keypad, the global address “*” is used to create a string

output response displayed on the external keypad. This KP-10 global address causes the

accessed device to respond, regardless of its specific address.

CAUTION

Do not confuse the KP-10 global address (*) with the global address of zero referred to

in the M&C System Monitor Software User’s Guide. The zero global address causes

the accessed device to accept commands without responding.
