1 Product Description
The TIP866-TM-20 is a complete interface solution for the TIP866-10 (8 serial channels RS232), the
TIP866-20 (8 serial channels RS422) and the TIP867-10 (8 serial channels RS485). The TIP866-TM-
20 comes with a TA106-10 cable (0.8m ribbon cable with 50 pin ribbon cable connectors).
The 8 serial ports of the TIP866-10/-20 or the TIP867-10 are routed to 8 RJ45 connectors located in
the 6U/4TE front panel of the TIP866-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).
A two pin screw terminal (X9) can be used to p5V 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 TIP866-10
(RS232). Additionally DCD and DTR are supported for channel 1 and 2.
TXD+/-, RXD+/- and GND are supported for the TIP866-20 (RS422) and DX+/- and GND are
supported for the TIP867-10 (RS485).
This transition module can also be used with the IP-Octals. If the TIP866-TM-20 is used with the IP-
Octal RS232: do not connect jumpers on J11, J12, J21, J22: 9-10 and 11-12 because the IP-Octal
RS232 does not support DCD and DTR on serial channel 1 and 2.
