2.1 Hardware Interconnection – RS232 Interface
2.1.1 Visilynx 3 Modular (V3M)
The V3M ‘T226-E’ CPU card incorporates an RS232 ‘test and config’ port which allows
Visilynx 3 Modular to be connected, via a 9-way to 9-way interface lead, to an external PC for
system set-up and testing. Please refer to Figure 1.
2.1.2 Visilynx 3 Integrated (V3i)
The V3i System Unit incorporates an RS232 Test/Config connector port on the rear panel
which allows connection, via a supplied 9-way to 9-way interface lead (Bewator Ltd. Part
Number VC-3CONFIG), to an external PC for system set-up and testing. Please refer to
Figure 2.
2.1.3 Interface Lead
If the serial port on your PC is a 25-way connection, you will need to purchase a suitable 9-
way to 25-way ‘D’ type pre-wired interface lead to connect to V3 system.
(V3 trainborne
racks use a special cable to connect the PC to the rack PTE port.)
Tables 1 and 2, shown below, are for reference and give details of the pin-outs used for
RS232 transmission.
Note that the 25 to 9-way option is wired differently to the 9-way to 9-way cable. If
attempting to manufacture this lead, these pin-outs must be observed.
