er. Note that the Source Bypass for Arm Layer 2 and the Trigger Layer also loops around the
Delay.
If programmed for another pass through the specified layer (count >1), the bypass loop will not
be in effect even though it will still be enabled. The bypass loop will be in effect if operation
first goes back into the previous layer (or idle).
Enabling the Source Bypass for Arm Layer 1 and Arm Layer 2 also enables their Output Trig-
gers. When operation leaves Arm Layer 1 or Arm Layer 2, the appropriate output trigger pulse
will occur. If the Trigger Link (TLINk) control source is selected, the output trigger will be
available on the programmed Trigger Link output line. For all other control source selections,
the output trigger pulse will be available at the CHANNEL READY Output connector. The Out-
put Trigger in these two layers is disabled when the Source Bypass is disabled.
The Output Trigger in the Trigger Layer is always enabled and occurs after the Device Action.
With ACCeptor selected, the bypass is disabled. Operation will not proceed through the speci-
fied layer until the appropriate event occurs.

Line 10 Enables the Source Bypass for the Trigger Layer and then queries the state of the
Source Bypass.
Line 20 Addresses the 7001 to talk.
Line 30 Displays the state of the Source Bypass (SOUR; enabled).
