The Mega_Link part number is in the format 7600-a b c d

The choice of in-built power supply is defined by the suffix ‘a’ in the part number:

• a = 1: 12Vdc nominal (4….16Vdc)
• a = 2: 24Vdc nominal (12…36Vdc)
• a = A: AC mains (85…240Vac)
• a = B: Alkaline battery pack (4 x D cells)

The choice of communication interface modules built into COM1 is defined by the suffix ‘b’ in the part number:

• b = 0: None fitted
• b = 4: 458MHz Radio
• b = 8: 869MHz Radio
• b = G: GPRS radio modem

There is a similar choice of optional second communication interface module built into COM2, defined by the suffix ‘c’ in the part number.

Suffix ‘d’ of the part number defines whether or not the LCD colour display and joystick are fitted:

• d = 0: No display
• d = D: Display fitted

COM3 provides an RS232 or RS485 interface and these can be easily connected to third party equipment by using our DB9 – RJ45 Adaptors.
