It uses a single-directionprotocol meaning that it can send commands out to the camera(s) but not receive any databack from the unit.The DVR is set by default for RS485 to be disabled for each channel. Therefore, PTZ settingsmust be enabled before PTZ cameras can be utilized. This system supports 26 of the mostcommon protocols including Pelco-D and Pelco-P.When connecting a PTZ camera, the following should be taken into account:• Ensure that the camera has the same grounding with the DVR otherwise you may not beable to control the PTZ. Shielded twisted wire is recommended with the shielded layer beingused to connect to the ground. Improper grounding may result in chip damage.• For excessively long wire runs, or if multiple PTZ cameras are connected to the DVR, 120Ωshould be parallel connected between the A and B lines on the far end to reduce reflectionand maintain the signal quality• The 485 port of this DVR cannot parallel connect with the 485 port of another device• The voltage between the A and B lines of the camera should be less than 5V.NO C1NO C21 2 3 4 5 6 7 8A BCNTRL12VRS-485STEP 1.
