Description
Check link addressing, detected data rate, and transmit/receive bit states during relay commissioning or bench testing. Front-panel pushbuttons let technicians simulate transmitted bits, while the LCD and LEDs provide immediate link feedback. Battery operation supports work at the relay panel without a separate power supply.
