1.8 J5 – RS-232 Communications Port & Serial Cables
1.8.1 Connecting the programmer to the PC COM port
The programmer communicates with a PC via the RS-232 Communications Port (J5). A suitable 9-
way to 9-way serial cable is supplied with the programmer.
The programmer is supplied with the following PC Serial Cables / Adaptors:
This cable should be connected between the 9-way D-connector on the programmer and a spare 9-
way RS-232 COM port on your PC.
9-9 way Serial Cable as shown in the diagram below.
1.8.2 Serial Cable Length
The serial cable supplied with the programmer is approximately 2m in length. If you wish to make your
own longer cable, please ensure that you connect all 9 pins at each end in a straight-through pin-to-
pin fashion. See fig. 1.7.3 for the pin-out specifications. The programmer features an ESD protected
full RS-232 specification driver chipset and so should operate reliably when driving serial cables up to
10m in length. However, it is recommended to keep the serial cable as short as possible to enhance
EMI immunity and reduce EMI emissions.
Important note:
The programmer uses ALL of the NINE pins of the COM port for different purposes. It is therefore
imperative that the cable used to connect between the programmer and the PC COM port has all
NINE cables connected. Failure to do this will result in the programmer not operating correctly.

If your PC has a 25-way D connector, you will need to plug the 9-25 way adapter onto the end of the
1. 9-way D (female) to 9-way D (Male) Serial Cable
2. 9-way D (female) to 25-way D (Female) adaptor
