HSU Card HSU Card User Screens and Settings
On the HSU-T V11 and HSU-T 35 Cards, the CTS settings are used only if the port Mode is
set to dce. The default setting in that mode is perm. For a dte port, the only available setting
is n/a.
CTS DELAY
The Clear To Send (CTS) Delay setting delays changes in the CTS signal in the local mode.
Enter the value you need in milliseconds. The available options are 0, 30, 60, and 100 ms. If
you do not know what value you need, start with 0 (zero) ms and increase the value gradually
until you no longer experience problems. The CTS option above must be set to locl before the
CTS DELAY setting has any effect.
On the HSU-T V11 and HSU-T 35 Cards, the CTS Delay settings are used only if the port
Mode is set to dce. The default setting in that mode is 0 (zero). For a dte port, the only
available setting is n/a.
LOCAL LB
The Local Loopback (LOCAL LB) option activates a loopback on the selected card port.
Choose the dte setting to loop the outgoing data from the external DTE device back to the
DTE receiver. This loopback (see Figure 14-7
7
) allows you to check the local cabling and
most of the circuitry in the HSU Card. It also disconnects the incoming data from the far end.
