Omega Vehicle Security OMG-USB-DIO48 manual Pull Ups

Technical

Pull Ups

Ten pin bussed resistor packs are installed to provide pull-ups to the input ports. These are installed on all ports. The pull-up resistor packs are rated at 10K ohms. Figure 2 below provides the bussed resistor and corresponding port. The resistors insure that no line is floating which is not connected. This provides consistent biasing on all un-terminated lines.

Bussed	Corresponding
Resistor	Port
RP3	Port A1
RP2	Port B1
RP1	Port C1
RP6	Port A2
RP5	Port B2
RP4	Port C2
