Data Metering Option (SW1-5)

When the data metering option is disabled (SW1-5 set to "OFF"), the transfer speed of the 7400B Data Module will adjust to match the transfer speed of the remote system. The C0NNECT xxxx message displayed when a connection is completed will always indicate the far end speed.

When this option is enabled (SW1-5 set to "ON"), it allows the user to set-up a call to a remote end device that is running at a lower speed than the local data module. The CONNECT xxxx message will always indicate the speed of the local data transfer. The data module performs the speed conversion and uses the CTS lead to flow-control the user’s terminal if it is sending too much data too fast. During the data transfer, the DATA METERING LED indicates the state of the CTS lead.

Note: If you are using a PC with a data communications package, or a dedicated terminal that does not support CTS control, you cannot make file transfers with the data metering option enabled.

A change in the setting of this option becomes effective immediately when the data module is in the idle mode or as soon as it is returned to the idle mode. The data module is in idle mode any time that it is not in test mode or connected to an active data call.

Make Busy on Local Loop Option (SW1-8)

This option controls the make-busy feature of the 7400B Data Module. When the option is enabled (SW1-8 set to "ON"), the data module will busyout the DCP line when either the Local Loopback or Local Loopback/Self-Test mode is entered. The busyout condition is released when the test ends.

idle mode any time that it is not connected to an active data

 

call.
