INSTALLATION REQUIREMENTS/SPECIFICATIONS
JAM Output: | Collisions are propagated |
| through the network using the |
| JAM signal of an alternating |
| pattern of 1's and 0's in |
| accordance with 802.3 |
| specifications for a repeater unit. |
Fragment Extension: | Packet fragments are extended to |
| a minimum of 96 bits using the |
| JAM [1,0]. |
Fault Protection: | Each segment will disconnect |
| itself from the other segments if |
| 32 consecutive collisions occur, or |
| if the collision detector of a |
| segment is on for longer than |
| approximately 110 ∝s. This fault |
| protection will reset |
| automatically after one packet is |
| transmitted/received onto the |
| fault protected segment without |
| causing a collision. |
POWER SUPPLY REQUIREMENTS
Note: The SEHI has a universal power supply. This unit allows you to use an input power from 90 to 264 VAC,
The power supply has two outputs of +5 volts and +12 volts. The maximum output power is 40 watts and the minimum efficiency is 65% under all conditions of line at full load. The minimum and maximum load current from each output is shown below.
Output | Min. Load | Max. Load | Max Power |
+5 Volts | 0.75 Amps | 4 Amps | 20 Watts |
+12 Volts | 0.00 Amps | 2 Amps | 24 Watts |
