NOTE: prox.pad plus RS 485 communications--Theprox.padplusunitcommunicateswith
the host computer via the IEI RS232-RS485 interface (part number IEI232-485). For additional
details see pages 16 and 17. For wire specifications, see page 23.
NOTE: Use with IEI Secured Series™ (Hub, Hub Max, Hub MiniMax) Networks--The RS
485 network characteristics for the prox.pad plus unit are different than those of IEI's Secured
Series access systems. This means the prox.pad plus unit can operate in the same system
as Secured Series controllers but not on the same physical network. Hub Manager Profes-
sional software (v5 or higher) can manage Secured Series doors and prox.pad plus doors
(and LS doors as well), but these door controllers cannot be “connected” to the same
network and network wires. Secured Series communication is RS-232; prox.pad plus
communication is RS-485. These communication protocols are different. However, the ability
of the Hub Manager Professional software to set up multiple local and LAN/WAN sites makes
this an advantage rather than a problem.
