Notes |
| 1 |
VeeT |
Transmitter Ground |
The module signal grounds are isolated from the module case |
| 2 |
TX_Fault |
Transmitter Fault (LVTTL-O) - High indicates a fault condition |
This is an open collector/drain output that on the host board requires a 4.7KΩ to 10KΩ pull-up resistor to VccHost. |
| 3 |
TX_Disable |
Transmitter Disable (LVTTL-I) – High or open disables the transmitter |
This input is internally biased high with a 4.7KΩ to 10KΩ pull-up resistor to VccT |
| 4 |
SDA |
Two wire serial interface Data Line (LVCMOS-I/O) (MOD-DEF2) |
Two-Wire Serial interface clock and data lines require an external pull-up resistor dependent on the capacitance load. |
| 5 |
SCL |
Two wire serial interface Clock Line (LVCMOS-I/O) (MOD-DEF1) |
Two-Wire Serial interface clock and data lines require an external pull-up resistor dependent on the capacitance load. |
| 6 |
MOD_ABS |
Module Absent (Output), connected to VeeT or VeeR in the module |
This is a ground return that on the host board requires a 4.7KΩ to 10KΩ pull-up resistor to VccHost |
| 7 |
RS0 |
Rate Select 0 – Not used, Presents high input impedance |
- |
| 8 |
RX_LOS |
Receiver Loss of Signal (LVTTL-O) |
This is an open collector/drain output that on the host board requires a 4.7KΩ to 10KΩ pull-up resistor to VccHost |
| 9 |
RS1 |
Rate Select 1 – Not used, Presents high input impedance |
