TS-7180 Multitech Socket

From embeddedTS Manuals

The Multitech socket supports Multitech's Socketmodem modules to provide cell connectivity.

This header is compatible with the USB or serial based modules. The Multitech header supports up to 64 pins, but the TS-7180 only connects the pins it needs to support the modules.

Turn on a cell modem with: 

gpioset 5 17=1

25 USB_VBUS / CELL_MODEM_5V
26 GND
27 USB_MULTI_P
28 USB_MULTI_N
33 N/C
34 RXD_MODEM_5V [2] [3]
35 TXD_MODEM [3]

  1. ↑ Connected to the FPGA, but presently not supported. Sampled datasheet does not require this to be driven and will default out of reset.
  2. ↑ This is a 5V tolerant TTL UART input.
  3. ↑ 3.0 3.1 By default, no uart is mapped here. These are remapped through fpga reg 307. For example, to remap UART3(/dev/ttymxc2) run "tshwctl --addr 308 --poke 1"
  4. ↑ Turn on power with "gpioset 5 17=1"
