On the top side panel of the electronic unit (Fig. 7) there are the following sockets and
connectors:
1. USB cable for connection to USB port of PC, USB hub or USB/LAN hub.
2. Connector for PhS-1 LED photic stimulator or adapter for standard pattern stimu-
lator or TU-1 trigger unit.
3. Trigger socket (trig-in/trig-out) to attach equipment of third-party manufacturers
(see Annex 3): directly or via TU-1 trigger unit.
