An extended working range dataform reader (10) having a camera assembly (26) and a circuit board including gain and exposure control circuitry (56) which sets an initial gain value and exposure period from a previous data form reading session. If necessary, the gain and exposure are adjusted from their initial settings using image data from successive image fields in an open loop feedback scheme. The latency period for realizing the correct values and resultant power consumption is thereby reduced. Additionally, the readermodule (10) realized on the control circuit board (56) has an output port (53) which emulates the output of a laser scan module in order to readily integrate with and communicate with existing laser based dataform reading systems and devices.
