Section 2 - Communication Card Identification and Physical Port
Characteristics
The communication connector at the front of the unit (near the target LED’s) communicates to the ECP or
WINECP configuration program. This communication port is referred to as COM 0 and is common to both the
TPU2000, and TPU2000R.The protocol emulated through this front port is an addressable emulation of
STANDARD 10 BYTE PROTOCOL. With the addition of a communication card option, the unit emulates the
protocols described in Table 1-1. The inclusion of optional communication boards enables the rear ports (as
shown in Figure 2-2) of their respective units.

Figure 2-2. Physical Optional Communication Card Port Locations
The TPU2000 and TPU2000R differ in physical appearance. The communication cards inserted within the unit
also differ in form, fit and construction. A typical TPU2000 and TPU2000R’s communication card is illustrated in
Figure 2-3 of this document. As shown, the TPU2000R has two physical interface connectors built onto the card.
The form factor of these connectors are industry common DB 9 and “PHOENIX 10 POSITION” connectors. The
“PHOENIX 10 POSITION” connector has a capacity to land two 18 wire gauge conductors at each position. The
TPU2000 has the communication port connectors fixed as part of the chassis. The physical card slot for housing
the communication card is marked on the chassis as “COM”. The communication card mates with internal
connectors allowing electrical and physical connections for the communication card and chassis mounted
physical connectors.
