4.3 Interface module numbers
Redirecting display commands to a printer or serial interface module connected
to the JX2 or JX3 system bus requires configuration of the module number.
Redirection to an internal user-programmable serial interface is unambiguously
defined by the device number. Therefore, no additional configuration is required.
The module number to be entered is calculated based on the number of the mod-
ule on the system bus plus a system bus constant:
Module number = number of the module + system bus constant
