2.2.3 Elevator Control Terminals

The elevator control terminals are used when the 2348-010 elevator control board is connected to the system to enable elevator control. Do not connect any other devices to these terminals.

Maximum wire run for weigand data is 500 feet using Belden 9931, Consolidated 5324-CL, or equivalent six (6) conductor shielded wire. Do not use twisted pair with weigand format. Float the shield at the elevator control board. Do not connect the shield to the elevator board common.

If elevator control boards (2348-010) are being used with this system, refer to the Elevator Control Installation and Wiring manual that came with the elevator control boards, for detailed information on wiring these boards to the PC programmable telephone entry system.

The PC programmable telephone entry system may be programmed using the RS-232 serial communication terminal. This terminal allows a direct connection to a computer using a standard DB- 9 serial connector on one end, and loose wires on the other that connect to the RS-232 terminals on the board. You can order a 6-foot cable from DoorKing (P/N 1818-040), or make your own using the wiring scheme shown below. A cross reference is also provided for a DB-25 connector.
