The UNIV-TTLIN/IL Universal I/O module provides two TTL level inputs to the Event Generator. The input terminated can be set by a jumper to either 50 ohm to ground or 240 ohm to +5V. The inputs are 5V tolerant even when powered down.
Input specifications are following:
| parameter | value |
| connector type | LEMO EPK.00.250.NTN |
| input impedance | 50 ohm, 240 ohm or high impedance |
| VIH | > 2.3 V |
| VIL | < 1.0 V |
