TPMC866-11 TEWS 8 Channel Serial Interface

The TPMC866 is a standard single-width 32 bit PMC module and has eight channels of high performance serial interface with front I/O and back I/O.
The TPMC866-10 offers an 8 channel RS232 interface and supports Receive Data (RxD), Transmit Data (TxD),
Ready-To-Send (RTS), Clear-To-Send (CTS) and GND for each channel. Additionally serial channel one and serial
channel two provide Data-Set-Ready (DSR), DataTerminal-Ready (DTR), Data-Carrier-Detect (DCD) and Ring-Detect-Indicator (RI).

TPMC866-11

The TPMC866-11 supports an 8 channel RS422 interface and offers RS422 signal levels by differential transmitters and receivers. The Transmit Data (TxD +/-), Receive Data
(RxD +/-) and GND are provided for each serial channel. The receiver signal termination (120ohms between RxD+ and RxD-) is provided on the TPMC866 per channel.
Each channel of the TPMC866-10/-11 has a 64 byte transmit FIFO and a 64 byte receive FIFO to significantly reduce the overhead required to provide data to and get
data from the transmitter and receivers. The FIFO trigger levels are programmable.

The TPMC866-12 provides an 8 channel of high performance serial interface. Each serial channel can be configured by a DIP switch to operate as an RS422,
RS485-FD-M (Full Duplex Master), RS485-FD-S (Full Duplex Slave) or RS485-HD (Half Duplex) interface. For
RS422 and RS485-FD a four wire interface (RX+, RX-, TX+, TX-) plus ground (GND) is offered. For RS485-HD a two wire interface (DX+, DX-) plus ground (GND) is
supported. For the front I/O a HD50 SCSI-2 type female connector is located in the front panel. For the back I/O the
P14 I/O connector is supported. Each channel of the TPMC866-12 has a 128 byte transmit FIFO and a 128 byte receive FIFO to significantly reduce the overhead
required to provide data to the transmitters and get data from the receivers. The FIFO trigger levels are programmable.
