Step 1 – Setting the cable length jumpers/switch

(PC, SUN, PC-Serial/Audio models. See Figure 5.)

There are three jumpers labeled JP3, JP4, and JP5, located on the Remote Units PCB. These three jumpers set the correct level of video equalization for different cable lengths. Jumpers JP3, JP4, and JP5 are all factory set to a default of 0 – 300 feet. For cable lengths less than 300 feet, no jumper setting changes should be needed.

For cable lengths over 300 feet these jumpers may need to be set to compensate for the longer cable length. To set these jumpers, first carefully remove the Remote Units case by unscrewing the two side screws and the top screw and lift off the top case exposing the CrystalViews PCB. Orient the PCB with the cable connections away from you and the front panel towards you. Set jumpers JP3, JP4, and JP5 depending on the CAT-5 cable length between the Remote Unit and the Local Unit as show in Figure 5.

If you are unsure about opening the case and setting the jumpers, please consult technical support at Rose Electronics.

TIP: If you are using a CAT-5 cable that is close to the top end of the cable length range and a video resolution of 1024 x 768 or higher, you may achieve better video quality by selecting the jumper settings for the next higher cable length range. For example, if your CAT-5 cable length is 250 feet, you might achieve better video quality if you set jumpers JP3, JP4, and JP5 to the 301 – 600 setting.

(PC-Serial/Audio model only. See Figure 5.)

If you are using a non-powered microphone on the Remote Unit, install the “MIC” jumper on the daughterboard. This provides additional amplification.

DO NOT INSTALL THE “MIC” JUMPER IF USING A POWERED MICROPHONE.

(MINI model See Figure 5.)

The CrystalView MINI model has two Dipswitches located on the bottom of the Remote Unit. Set Dipswitch 1 according to the CAT-5 cable length used between the Local Unit and the Remote Unit. Maximum cable length for the CrystalView MINI is 150 feet. For normal scroll lock key operation set Dipswitch 2 to “ON”.
