1 Product Description
The TPMC866-TM-20 is a complete interface solution for all versions of the TPMC866: The
TPMC866-10 (8 serial channels RS232), the TPMC866-11 (8 serial channels RS422) and the
TPMC866-12 (8 serial channels RS422/RS485). The TPMC866-TM-20 comes with a TA105-10 cable
(0.8m ribbon cable with 50 pin ribbon cable connector and 50 pin SCSI-2 male connector).
The 8 serial ports of the TPMC866 are routed to 8 RJ45 connectors located in the 6U/4TE front panel
of the TPMC866-TM-20.
Jumper fields are provided for each channel to select the port configuration (DTE / DCE) for RS232
(Jn1 / Jn2) or RS422 (Jn3 / Jn4) and to select termination for the RS422 receiver (Jn5: 5-6, 7-8) or
RS485 (Jn5: 1-2, 3-4). Please refer to the notes in chapter “RJ45 Pin Assignment” !
A two pin screw terminal (X9) can be used to provide +5V to pin 1 of the RJ45 connectors of channel 3
to 8 and to supply the on board termination for RS422 and RS485. The +5V can be individually
selected by jumper for each of the channels 3 to 8 (Jn5: 9-10).
TXD, RXD, RTS, CTS and GND are supported for each of the 8 serial channels of the TPMC866-10
(RS232). Additionally DCD and DTR are supported for channel 1 and 2.
TXD+/-, RXD+/- and GND are supported for the TPMC866-11/12 (RS422) and DX+/- and GND are
supported for the TPMC866-12 (RS485).

Figure 6-1 : Jumper Field Jn5
Jumper Configuration Notes:
There are 5 jumper fields per serial channel n (Jn1 to Jn5) (n = Serial Channel 1 to 8).
Jn1 to Jn4 are used to select the desired RJ45 pin assignment and function as shown in the
RJ45 pin assignment tables.
Only one jumper field of Jn1 to Jn4 must be installed at a time. A jumper field Jn1 to Jn4 is
installed by plugging all jumpers of the jumper field. Remove all jumpers from the other jumper
fields of the Jn1 to Jn4 group.
Channel 1 and 2 of the TPMC866-TM-20 additionally support DCD and DTR for the TPMC866-10.
Default configuration for TPMC866-TM-20: all jumpers installed on Jn1 => RS232 DTE.
Jn5 is used for enabling an on board 120R termination resistor for the RS422 and RS485
modes.
If on board termination is desired, only one termination block of jumper field Jn5 must be
installed at a time. Either 1-2, 3-4 for the RS485 mode or 5-6, 7-8 for the RS422 modes. If RS232
modes are selected or on board termination is not desired, leave Jn5 1-2, 3-4, 5-6, 7-8 open.
Using the on board termination feature requires a +5V power supply at the X9 connector (2 pin
screw terminal).
Do not use the on board termination feature of the TPMC866-TM-20 when connecting a
TPMC866-11 (RS422) because there are termination resistors on the TPMC866-11 !
The TPMC866-12 provides jumper selectable on board termination for RS422 / RS485. If the on
board termination of the TPMC866-12 is enabled then do not use the termination jumper fields
of the TPMC866-TM-20 !
Support of +5V at pin 1 of the RJ45 connector for channel 3 to 8 is jumper selectable (Jn5: 9-
10) and requires a +5V power supply at the X9 connector (2 pin screw terminal).
