RS232 Serial Port

To interface the MAXPage with a third party paging system that is outputting the

TAP, COMP or SCOPE protocols, use the female DB9 on the rear of the MAXPage

unit.

1. The pin-outs for this serial connector on MAXPage are shown below:

2. When connecting the device to an IBM PC with the MAXPage Windows® software

installed, a straight through cable is used. See the Windows® MAXPage Software section

for more information regarding this.

3. Depending on the type of third party paging system you are connecting to you may need

either :

• A straight through cable where each pin is wired straight through with TX-TX,

RX-RX and so on.

• A null modem crossover cable that has all pins wired straight through except for

the transmit and receive lines which are crossed (TX-RX and RX-TX).

The section below explains how to make each type of cable if required. Alternatively they

can be purchased at a local computer or electronics store.
