MODULAR SMART SWITCH

Timeout Period

When a user has sent no data for the timeout period, the Modular Smart Switch is able to switch to another user. The default timeout setting of 16 seconds is suitable for most applications. If printouts are ever merged, increase the timeout period. Switches 1 and 2 on the base board control the global default timeout period used by all the ports. Individual port timeouts can be set using the software (see Chapter 6) or by sending software commands (see Chapter 9).
