** 8 mA for units manufactured prior to May 2006.
*** Absolute maximum ratings are ±20 VDC for the DTR line, and +20, -25 VDC for the TXD line. Full
EIT/TIA-232 and V.28/V.24 compliance requires that these lines withstand ±25 VDC. Absolute
maximum ratings for units manufactured prior to May 2006 are ±16 VDC for the DTR line, and +16,
-25 VDC for the TXD line.
† A note about “port-powered” readers –These readers operate off some combination of otherwise
unused RS-232 lines, DTR and TXD in this case. Per the RS-232 specification, these lines are
