The V680-CHUD, V680-CH1D and V680-CH1D-PSI are handheld devices that read and write V680-series RF tags. The V680-CHUD has a USB 1.1 connection and is offered with a 0.8 m or 1.9 m cable. The V680-CH1D has an IBM PC/AT-compatible RS-232C (9-pin D-SUB) connection and a 2.5 m cable; the V600-A22 AC adapter is ordered separately. The V680-CH1D-PSI is designed for a Zebra Technologies handheld terminal; its built-in RS-232C interface communicates with the recommended handheld terminal through the included USB conversion cable. The devices work with 1 KB, 2 KB and 8 KB V680 tags.
The devices are powered from 5 V DC ±5% and draw 500 mA max. Operating temperature during communication is 0 to 40 °C, storage temperature −25 to 65 °C and operating humidity 35–85%. Degree of protection is IP63 excluding the connector section; the main unit is not resistant to chemicals or oils. Weights, including connector and cable, are approx. 110 g for CHUD 0.8M, approx. 140 g for CHUD 1.9M, approx. 170 g for CH1D and approx. 120 g for CH1D-PSI. Insulation resistance between connector and case is 50 MΩ min.
