C
External
Reference
Type
Sets the type of External Analog Reference connected to
the VTS. If set High, then sync input is selected (4 V
sync); if set Low, then composite input is selected (300
mV).
Composite
D
Test mode
Toggle On to enable the
Test
mode. If an RS-232 port is
connected to J1, then debug messages will be transmitted
from the VTS to the RS-232 port. Set the computer
terminal interface to no stop bits, 8 bits, and 1 parity bit
(N81). This mode is meant for debugging purposes and
should not be accessed during normal operation.

Serial Time
Delay
Replace Serial Time Delay works only if Replace Serial
(
SW1
position 3) is enabled. If Insert Black (
SW1
position
B) is set for “Output other PGM Input”, the Time Delay is
set to X value other than 0 sec (0 to 15 sec in 0.5 sec
increments).
When either output is replaced by Serial Input on PGM 1 IN
or PGM 2 IN due to signal loss or noisy signal, it will take X
amount of time to recover from the moment when the
original Input signal is fed back to PGM 1 IN/PGM 2 IN.
Example:
• When PGM 1 IN is lost, PGM 2 IN is fed to PGM 1
OUT until PGM 1 IN becomes continuously valid
throughout the delay time.
• Once valid and delay time has passed, it will switch
back to PGM 1 IN to PGM 1 OUT.
• The process is identical for PGM 2 IN.
