Modifier = single digit (1 through 6); response = single ASCII digit, 0 if the
corresponding relay is inactive, 1 if active. See Example 1.
Modifier = B ; response = a byte of data with bits 0 through 5 set/clear according to
whether the corresponding relay is active/inactive. Bit 6 will always be set to
guarantee that the returned byte will not appear as a terminator byte.
See Example 2.
Modifier absent; response will be a string of 6 ASCII 0's and 1's separated by
commas giving the status of all six channels. See Example 3.
Examples: Assume that channels 1 - 3 are active, and 4 - 6 are inactive:
1. From computer: PCS 1 CRLF
From 370: 1CRLF
2. From computer: PCS B CRLF
From 370: GCRLF
(Note that ASCII “G” corresponds to the bit pattern 01000111 and represents the status of the
PC channels in bits 0 through 5).
3. 3.From computer: PCS CRLF
From 370: 1,1,1,0,0,0 CRLF
GTL
Definition: Send control back to the electrometer front panel settings.
Modifiers: None
Response: OK if command accepted, or INVALID if rejected.
LLO
Definition: Local lockout of the electrometer front panel gauge control settings.
Modifiers: None
Response: OK if command accepted, or INVALID if rejected.
Error Messages
If an error is found in the incoming message, the following messages will be returned in place of the
normal response.
OVERRUN ERROR - Returned if the incoming message overflows 370's buffer.
SYNTAX ERROR - Returned if the message fails to parse as a valid 370 command.
4.15 Gauge Serial Number Display and Channel Data Swapping
4.15.1 Stabil-Ion Gauge Serial Number Display and Channel Data Swapping
If there is a need to swap the data in the internal data tables due to a change in the location of the
Stabil-Ion Gauge with respect to cable or channel number, there is a provision to swap gauge
memory data into an area called TMP. This TMP area is also used to store data from the Memory
Module when a module has been plugged in for more than 15 seconds after power up. The TMP
area is cleared of data when the Controller is powered down and powered up. In the following
