UPGRADING RAM AND FLASH EEPROM
5.
Remove the unit from its mounted position by removing the four user-supplied screw assemblies from
the mounting flanges.
6.
Remove the top end cap on the power supply end of the M4RTU/M4 I/O base unit by removing the two
screws at the top corners of the end cap.
7.
Grasp the edge of the I/O and processor boards and pull firmly until the two boards disengage from the
M4BUS and slide completely out of the M4RTU/M4 I/O enclosure.
8.
Gently pull the I/O board up and away from the processor board to separate the two boards. (The I/O
board is parallel and on top of the processor board.) Carefully set the I/O board aside.
9.
Using a chip puller, carefully remove the U13 and U15 chips for a RAM upgrade or the U12 and U14
chips for a flash EEPROM upgrade.
10. When upgrading flash EEPROM, install each chip in its correct position (U12 or U14). Each will be
marked with its position. (See Figure E-1.)
When upgrading RAM, you may install either chip in either position (U13 or U15).
Note:
Ensure that the chips are correctly oriented; the notch on the chip should line up with the notch on the
silk screen on the board.
11. After correctly positioning each chip, make sure it is securely seated; however, do not attempt to force
or bend the chip in place!
12. Once all chips are physically installed, set the jumpers located on the processor board to correspond to
the new RAM or flash EEPROM size. See “Setting Configuration Jumpers and Switches” in Chapter 3
and refer to Table 3-2 for proper jumper settings.
13. To put the unit back together, undo steps 1–8 in reverse order.
