3.3 WIRING – UNSHIELDED TWISTED PAIR (UTP) OPTION, CONTINUED
3.3.2 HD6 Rugged Housing Installation
1. If this is the last dome in a daisy-chain wiring loop, the receive and transmit
communication must be terminated. All intermediate domes must be unterminated.
If this is the only dome on a data line, the receive and transmit lines must be
terminated. Install Jumper W1 on pins 1 and 2 (terminated) to terminate the data.
Install Jumper W1 on pins 2 and 3 (unterminated) to unterminated the data. Install
Jumpers W2 on pins 2 and 3 on all domes.
NOTE: UTP video cannot be daisy-chained.
2. Jumpers W3 and W4 define the type of cabling being used for video and data.
Refer to the jumper table in Figure 17 .
3. If the UTP option is used, DIP Switch SW1 must be set. The switch setting is
determined by the cable length between the control output port and the HD6. Use
the lowest switch setting possible for the cable distance. For example, if the UTP
cable run is 900 feet, set switch SW1-2 (600-900 feet) ON.
NOTE: Make sure only one switch is set to ON. Refer to the table in Figure 17 .
NOTE: If an active video receiver (e.g., NVT Model NV-652R)
is used at the monitor end, set all the switches to OFF.
If the video compensation is not strong enough at this setting,
set switch S1-1 to ON. Ensure that all other switches are OFF.
