SW1-SW4: switches for video input high/low impedance con-
nection setting.If one video input is connected to a terminal
equipment suchas monitor with high impedance, the switch
bit to this video input sho uld be set as ON with a 75 o hm
impedance load; if the terminal equipment such as monitor
has already been connected to a 75 ohm impedance, the
switch bitto this video input should be set as OFF and this is to
reach high impedance status. Refer to the following form for
the sw itch bit num ber to each video input. Factory default
setting are all as ON.
2)
SW5: this gro up o f sw itc he s are fo r sy ste m se tting.
Switch bit 1, switch bit 2 are for system reset setting. If the two
bits are all set as ON, the system is reset and all data in the
memory are cleared. Switch bit 3, switch bit 4 are for factory
reserved.
NO TE: A fte r c o m ple ting sy ste m re se t using the tw o
bits (and self- te sting is no rm al afte r sw itc hing po w e r
o n), use r sho uld se t the thre e bits as O FF again.
Sw itch bit 5, bit6, bit7 & bit 8 are for wo rk m ode se tting.

SW6: this switch is for c ommunication matching impedance
setting. In the communication process, when the communi-
cation distance is too long or the internal resistance of trans-
mitting line is too large, abnormal communication will arise.
Now user should connect the matching impedance to the
communication equipments.
Switch bit 1, bit 2 & bit 3 are not in use now and should be set
as OFF.
Switch bit 4 is set as ON, the expansion communication port
is connected to matching impedance (default setting is OFF).
If switch bit 5is set as ON, the RS485 communication port 1 is
connected to matching impedance (default setting is OFF).
If switch bit 6is set as ON, the RS485 communication port 2 is
connected to matching impedance (default setting is OFF).
If switch bit 7is set as ON, the RS485 communication port 3 is
connected to matching impedance (default setting is OFF).
If switch bit 8is set as ON, the RS485 communication port 4 is
connected to matching impedance (default setting is OFF).

If switch bit 1is set as ON, the RS485 communication port 3 is
connected to matching impedance (default setting is OFF).
If switch bit 2is set as ON, the RS485 communication port 4 is
connected to matching impedance (default setting is OFF).
If switch bit 3is set as ON, the RS485 communication port 2 is
connected to matching impedance (default setting is OFF).
If switch bit 4is set as ON, the RS485 communication port 1 is
connected to matching impedance (default setting is OFF).
If switch bit 5is set as ON, the RS485 communication port 5 is
connected to matching impedance (default setting is OFF).
If switch bit 6is set as ON, the RS485 communication port 6 is
connected to matching impedance (default setting is OFF).
If switch bit 7is set as ON, the RS485 communication port 7 is
connected to matching impedance (default setting is OFF).
If switch bit 8is set as ON, the RS485 communication port 8 is
connected to matching impedance (default setting is OFF).
