Terminators are two terminators to be installed on the coaxial cable, one for each cable end. One terminator, instead of two, requires a ground connection.
The terminator must have a specific resistance value, depending on the network:
Network type numerical value Ethernet RG-58A/U (fine mesh) 50 ohms
Ethernet RG-59/U (coarse mesh) 75 ohms
ARCNETRG-62/U 93 Ohms
The terminator can tell the SCSI master controller where the whole bus ends, and send a reflection signal to the controller. It can only be used when a termination signal is made at two physical terminals SCSI bus 。 IDE interface It is very easy to use. It can be used as long as the master device and slave device are set, while SCSI is troublesome to use. You need to set the "termination" to use it. The so-called "termination" is to set one on the last SCSI device Jumper Or install a finalizer to notify SCSI controller The SCSI bus ends here.
