Keyscan Inc. A Member of the Kaba Group – CA8WL-AL Rev. B Installation Guide (07.15)
22
The total number of CA8WL-AL / PIM400-485 kits installed for operation with Aurora is limited by one of the
following factors:
Serial/USB communication - the number of available server/workstation communication ports
Network communication - the number of IP connections supported by the server’s operating system
Reverse network communication – the number of RN licensed IP connections
Keyscan RS-232 Data Cable
If using Keyscan’s RS-232 data cable, it has multiple applications for various Keyscan products and as such
has a generic configuration for the loose wires. When it is used in applications where the shield must be
connected to the metal enclosure ground lug, Keyscan suggests one of following wiring options:
Option A – trim back the shield wire to approximately 0.5” (1.5 cm) then solder an appropriate length of
green # 20 AWG wire to the shield and terminate the shield at the ground lug
Option B – remove sufficient cable jacketing allowing the shield wire to return to the ground lug from the
communication connector. Trim the 5 communication wires to a length of 2.5” (6.5 cm) and strip the ends
Insulate the shield wire with a length of tubing to prevent it from shorting. Terminate the shield.
Configure a 9-pin RS-232 Data Cable
In the event that you are establishing a serial connection from the PC to the control board and you have to
make a 9 pin, RS-232, data cable, ensure that you follow the pin to wire colour assignments on the following
diagram. It is strongly recommended that you use a Keyscan 9 pin, RS-232 data cable (Keyscan part # 40-
2322) which is manufactured specifically for Keyscan serial data connections.

Installation Notes
Typically, the black wire of the RS-232 cable from the PC, which is the receive data input of the PC, is
connected to the serial port TD pin of most Keyscan products.
Typically, the red wire of the RS-232 cable, which is the transmit data output of the PC, is connected to
the RD pin of most Keyscan products.
