4 TMC-6700/1000 Series RS-232C Control

4.1 RS-232C Control Introduction

The TMC-1000’s DSP parameters and operation mode can be controlled by an external RS-232C

interface. The camera features four memory banks that store camera configuration parameters such as

shutter speed, color matrix, white balance, gain, and edge enhancement. The first two banks, Bank1 and

Bank2, can be selected via the Bank Switch on the back panel of the camera. Bank3 and Bank4 can be

selected via RS-232C control. This feature allows easy switching between different camera-control

parameters as application needs change. Each time the camera is turned on, saved data is loaded from

EEPROM to RAM Bank1.

The RS-232C control software does not have direct access to the EEPROM. Users can program the

EEPROM via the RAM banks. For instance, in order to change the gain value, it is necessary to access

the RAM address that holds the gain parameter to send new data to it. The RAM address is shown in

Section 6.3, “TMC-6700/1000 Series Control Parameter Address Map,” on page 36. Section 4.1.3

through Section 4.2.4 explains the following:

• how to set the RAM bank

• how to get the current RAM bank number

• how to save into and load from EEPROM.

Section 4.2.5 and Section 4.3.10 show how to write and read new camera parameters to and from the

RAM bank.

4.1.1 RS-232C Communication Defaults

Parity : None

Data : 8-bit

Stop : 1-bit

Baud rate : 9600 bps

If other communication conditions are required, please contact PULNiX.

4.1.2 RS-232C Command

The TMC-6700/1000 series command packet is in 8-bit binary code. When a packet is received by the

TMC-1000, it reads the internal packet of the received buffer. If it is the correct packet, then it processes

the parameters based on the commands detailed in Section 4.2.

4.1.3 RAM Memory Map

Each of four user’s RAM banks is mapped in the Appendix, Section 6.3, “TMC-6700/1000 Series

Control Parameter Address Map,” on page 36.
