applications and has an adjustable
U-bracket for bench or wall
mounting. On the sealed keypad, the
user can perform complex functions
with the push of a button. The
WM7600 has time/date battery
backup and audit trail accountability.
Both models feature bidirectional
RS232, RS485, RS422, and current­loop communications.
