Condition: Used
This Sytek 2502 broadband network modem has been inspected and appears to be in good used condition. The chassis shows the light yellowing and surface wear typical of equipment from this era. The rear panel shows some oxidation on the metal plate around the connectors, but all ports — Port 0 and Port 1 (DB25), the RF coaxial connector, the Reset button, and the 9-pin DC power connector — appear intact and undamaged. The front-panel Power and Status indicator LEDs are visible and the lens covers are present. No power supply is included — the unit requires an external DC supply per the specifications on the bottom label (+5V at 3.0A, +12V at 0.65A, -12V at 0.15A, 25W total).
