Connect Multiple Keyless Entry Systems to One Computer

Before You Begin

This scenario requires that all Keyless Entry Systems will use the same set of codes. You connect each Keyless Entry System, one at a time, to the computer and Transmit Codes to each keypad in sequence. First you’ll need to perform these steps:

1. Install the Keyless Entry System Hardware
2. Install the keyless Entry System Software Program on your computer.
3. Assign Codes in the Keyless Entry System program.

Note: If you want to have different sets of codes transmitted to separate Keyless Entry System keypads, you will need to Install the Keyless Entry System Program on separate computers and maintain codes and separate cable connections on each computer.

Transmitting and Monitoring Codes

The Keyless Entry System is only required to be connected to your computer to Transmit Codes, or to actively Monitor Codes as they are entered. In this scenario you can Monitor Codes on only one KES system at a time which is attached to your computer. However, because the codes are actually stored in the Keypad, you may Transmit Codes to one Keyless Entry System keypad, then disconnect the first system and connect the next system and Transmit Codes again, and so on to store the codes on any number of Keyless Entry Systems keypads.

Attaching the Communications Cable

The communications cable from each Keyless Entry System relay box is the same as a standard 4-wire telephone cord. This cord plugs into an RJ-11 port (looks like a telephone wall jack) on the supplied small putty-colored adapter that has a DB-9 (9 pins) connector on the opposite end. The DB-9 end connects to either 1) a Blue USBGear adapter (the USB end connects to computer’s USB port) OR 2) directly to the computer’s Serial port (DB-9 Female end of RJ-11-to-Serial Adapter connects to COM1 or COM2 on the computer).

Note: If using the supplied Blue USBGear adapter, see also: Installing USBGear Drivers.

If your Computer has only one physical serial port or only one USBGear adapter is used:

Connect the telephone cable from the first Keyless Entry System to the RJ-11 jack of the putty-colored adapter and Transmit Codes. Remove the first telephone cable and connect the 2nd cable to the same RJ-11 jack and Transmit Codes again, and so on.

If your computer has a permanent COM or USB port for each Keyless Entry System:

In this case, each connection is permanent, so you do not need to swap cables. Instead, change which port you are using to Transmit Codes each time by going into the KES program Options and change the COM port assignment (step 2b) when you need to transmit codes. For example if you have two Keyless Entry Systems, one connected to COM1 and one connected to COM5, you would choose COM1 first, Transmit Codes, then switch the port assignment to COM5 and Transmit Codes again.
